Lol russia.

Check out the troy2c us nuclear ramjet engine from the 60s. That thing looks legit... ran at 500MW for 5 mins in a ground test. Its a shame humanity started wasting our rocket and nuclear engineer level minds after the 70s or so. I blame hippies. We could be cruising around in mach 10 nuclear business jets.

According to my math... its the most badass jet engine ever made. Its thrust to weight ratio blows away anything i have ever seen. Like a380 level thrust(all 4 engines and then some) from a core the mass of an auto engine.

>>A generalized tendency towards violence and general high risk behavior. You just made a thread about it expounding on your driving skillz.

That was always my argument. Your reframing it is blatantly dishonest, trumptard.<<

No. The thread and my posts were about violent crimes. Your personal opinions about what the ”optimal” amount of risk taking in general is and your unhealthy relationship with ”violence” broadly are utterly uninteresting - they certainly don’t form a basis for ”rational decisions” in general. Explained this for you in the thread. Taking risks is a good thing in general, needed to survive and for progress.

You are welcome to live your pacified existence a stones thrown from the hut your grandfather skinned seals in. Never take risks and live to be a 100. I will not judge you.

Wow. The thread title is nuclear propulsion, not nuclear family.

The closer we come to clinical immortality, the higher the premium paid for risk behavior and premature death.

From a parental perspective: If best medical practices allow for the choice between an offspring prone to risk behavior and premature death or an offspring not prone to risk behavior and premature death...

Well, what is the rational choice and how will chosing rationally impact on gender ratios?

Jergul:

That nuclear family line made me snigger.

But seriously - the sodium would be a needless complication. By definition, it can only cool the reactor before it's combusted, but the reactor can't do much useful until the sodium is combusted. You also introduce a bunch more engineering challenges and two more mode transitions which are where things tend to go wrong.

You just don't need sodium to run a fast reactor if you have an open cooling cycle.

Plus liquid sodium is a pain to handle, especially when H20 is a combustion product of other stages.

It would be far simpler just to remove the control elements from the fast reactor a few minutes before transition to supersonic. It'll heat up really fast. No need for the coolant. Then open the intake for the scram jet (maybe use the scram jet with conventional fuel for a couple of minutes).

As for boiling kerosene being a problem - it's going to be combusted!

Hot liquid sodium isn't really using any of that nuclear power - the thermal energy isn't released until the working fluid expands. All you'd be doing is slowing down the reactor reaching the temperature need to heat the airstream and adding a really crap intermediate stage rocket. Meanwhile you've put a horribly corrosive, explosive, difficult to handle substance around your nuclear reactor which is going to complicate fuelling and maintenance.

NaK isn't needed here - the coolant is the working fluid.

>>The closer we come to clinical immortality, the higher the premium paid for risk behavior and premature death.<<

We will cross that bridge when we get there. In the mean time, mortality related to risky behavior is on the decline. It declines with age, technological progress etc.

>>From a parental perspective<<

From your* perspective.

>>If best medical practices allow for the choice between an offspring prone to risk behavior and premature death or an offspring not prone to risk behavior and premature death...<<

You have a very flat understanding of "risk" or what the spectrum of risky behavior entails. Risk is what every pioneer and entrepenuer engages in. The astronauts that burned to death in the Apollo capsule, they took risks. When Colombus sailed across the Atlantic, he and his crew took risks. When Gallileo told to pope to suck it, he took a risk. There is no future scenario where taking risks isn't part of the equation. Normally people take these risks when they are young. Some lose, but enough win to spread the risky genes. We all gain for those men taking those risks. Your welcome BTW.

>>Well, what is the rational choice and how will chosing rationally impact on gender ratios?<<

To have many sons, taking calculated risks and procreating with the help of artificial wombs.

From a societal perspective, what have women achieved that the rest of society has gained from?

You have to face it, once we have artificial wombs and sex dolls, there really are no rational reasons to keep women around.

The is nothing "nuclear" about men and artificial sex dolls, unless these sex dolls are powered by nuclear isotopes. Which is probably a bad idea.

Best medical practices will never involve selective abortions.

With technology we can project now, it would involve eggs harvested and frozen when women are 28 or so and gender sorted semen. Also stored for invitero placement at a later date.

"Remove the control elements from the fast reactor a few minutes before transition to supersonic. It'll heat up really fast."

If that is the timeline, then sure. The coolant is only needed if the nuclear reactor needs to be activate before launch.

"As for boiling kerosene being a problem - it's going to be combusted"

I was envisioning explosive expansion. Which would be a problem as well explosions. But that too would be an issue only if the reactor needed to start up pre-launch.

"the thermal energy isn't released until the working fluid expands"

NAK does burn nicely. So expansion would occur.

But as I said, if you are correct that the fast breeding nuclear reactor can go from cold start to working temperatures within a few minutes, then cooling is redundant.

I assumed that the reactor would have to start up before launch. And would for operational reasons need to be shut down capable before launch too.
Seb

Wed Aug 14 08:57:01
Jergul:

Oh I see. Well I think the reactor can't be on until it's some distance down range.

There's no mass or space for shielding, so it's going to give a massive dose of radiation to the launch vehicle and, if a fast reactor, irradiate it too.

Not ideal.

It should heat up pretty quickly, and assuming it's going from standstill, it'll need time to accelerate to scram jet speeds before the nuclear reactor is even useful.


Sure, the combusted Na will expand, but the heat of the reactor won't be meaningfully contributing to that. It'll go into the phase change of the sodium from solid to liquid and raising its temperature. I'm not sure hot liquid sodium Vs solid sodium will produce meaningfully different volume/temperature combustion products.

I'd use hydrogen.

Incidentally, I recall a decade or so ago reading that stone Russian agency was still into nuclear thermal space launch.

If I were to bet money on this, I think there's probably a couple of Russian Verner Von Braun's (Samsov Adamski perhaps) that have been trying to get their pet project funded and have convinced Putin to fund it as a weapon project when what they really want to do is go to orbit.

I'm not convinced this is a sensible weapon, and it's a bit of a nightmare to test for exactly the reasons we see.

I wonder what will happen when Putin realises this is a bit of liability?

If I was the US, I'd just ignore it until the Russians have tested it and provided verifiable telemetry. Either they'll need to breach international rules on nuclear pollution and get themselves excluded from IAEA, with the EU nations having more reasons to sanction them, or irradiate more bits of Russia.

NMD isn't aimed at Russia, Russia can defeat it without resorting to these cruise missiles, which can't be used conventionally.

So why should the US give up any capability to get them off the table?

Its ultimately not your problem. When you die, there will be no less than 98 men per 100 women on the planet.

It does not really even matter:

http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3222499/

"Men's risk of unintentional and violence-related injury overall is at least 2 and 3 times, respectively, that of women during each year of the last generation"

And you do realize that even full equality (1 fertilized male egg per female egg) would in itself dramatically change the gender balance as excess male mortality begins in the womb.

A 1:1 invitero placement ratio would give between 0.95 and 0.98 male per females at birth. Compared to today's 1.05.

I thought I was arguing that all men do not need to live at all.

But its otherwise just statistics. If group A dies faster than group B, then group A will become proportionately smaller as time passes.

It seems a rational decision for a parent to want their offspring to live as long as possible.

But even if we assume parents choose boy and girl fertilized egg implantation in equal measure, it would still cause a dramatic change in the gender ratios.

Because excess male mortality begins in the womb.

So, presumably the male excess death that starts in the womb can be solved by "advances in medicine".

Advances in behavioral genetics can solve detrimental violent behavior.

Advances in intelligence research can foster a new generation of strong, intelligently risk taking men and their lovely trophy wives.

Wishing that our children live for as long as possible seems to be a rational decision point.

When were you thinking men would adapt women's risk behavior? And if they did, would that not mean you lose no matter the chromosone composition? Men would for all practical purposes be women.

If risk behavior does not change, then men will always die quicker than women. Which means that there will be more women than men.

I am sure that there will always be natural births following natural conceptions. But as lifetimes expand, it will make more and more sense to delay childbirth by using eggs and semen gathered earlier in life.

Even an "I don't care" what gender approach would give an equal number of male and female egg implants.

I am actually suggesting an organic "advance in behavioural genetics to solve detrimental violent behavior" You seemed to have missed that.

Any change that modifies risk behavior to decrease male mortality is fine with me. Though virtual women sort of seems to defeat your argument.

You are a bit late in democracies at least:

I wish my children to live happy and be prosperous and not live in 1 dimension. There are trade offs, risks and rewards.

>>When were you thinking men would adapt women's risk behavior?<<

I make no predictions I just know the direction we need to go.

>>If risk behavior does not change<<

I certainly hope not, stagnation of the species would follow. Can you make omelettes without breaking an egg? Taking intelligent risks is a good thing, right now we can't have the cake and eat it too. Female level risk taking is stagnation.

>>then men will always die quicker than women. Which means that there will be more women than men.<<

There will always be more old women then old men. Arbitrary metric, insignificance etc. Besides no one needs to die in the future at all, I refuse your arbitrary limit to medical progress. In the future every man will have an IQ of 150 and take very intelligent risks.

>>Even an "I don't care" what gender approach would give an equal number of male and female egg implants.<<

Incorrect, it produces more males. More males are born than females. Even without third world goat herders aborting their females as they do. "The natural state".

>>I am actually suggesting an organic "advance in behavioural genetics to solve detrimental violent behavior" You seemed to have missed that.<<

With a 95+% error rate. We have talked about this already.

My version of the future has many possibilities. Plan A, Plan B, Plan C etc. You only have 1 straight line and that straight line is ruined by a fart in the wrong direction.

Of course we want our children to be happy and all that. And live for as long as possible. Self-harm is a significant reason for why men succumb to injury at much higher rates than women. Not exactly an indicator of happiness to end yourself would you not agree?

"Female level risk taking is stagnation"

I disagree. In fact, is not your worry that a society formed by women would change significantly?

"Incorrect, it produces more males. More males are born than females."

Incorrect. One male egg inserted for every female would give fewer males at birth. Excess male mortality begins in the womb. The "natural state" is actually compensating for a genetic mix that simply is less viable at every point.

"More linearity"
It is not linear. More women than men vote. Voting habits are probably fundamentally linked to aspects of male risk taking.

>>I disagree. In fact, is not your worry that a society formed by women would change significantly?<<

If I play along with your one dimensional prediction, it most likely would. Women would becomes more like man in their behavior. Thereby rendering it all pointless. The answer resides in the question I asked "what have women achieved..." nothing. They are far too balanced in their approach, and they can afford this, because men willingly and unwittingly take all the risks.

>>Incorrect.<<

In-incorrect, without any medling. Not caring about gender. What you do in a tube does not qualify as not caring for me. I have no data on what happens in this process and outright reject your results as jergulological.

>>More women than men vote.<<

Not linear, so you put in another assumption of linearity. Nice. So the US population has gone up over this period. The percentages are the same, actually no, data indicates that liberals are more likely to not vote. Women are more liberal as you know. Specially after Trump, women take defeats much harder than men. Another inherent weakness associated with risk taking. Losers.

Or you are seeing precisely what I am talking about. If these loser men give up in enough numbers on the democratic process, sooner rather than later those chickens will come back and burn down the roost. I think we are already seeing the chickens trickle in and starting small fires. Stop taking democracy for granted in a linear fashion. The US is boiling over, the safety valve in the UK has gone off, keep a close eye on Sweden the next 20 years, that now thanks to migration has a significant surplus of "loser men".

"We have to assume that he also thinks being wrong 95% of the time is a good enough debating style. His view of reality correlates "good enough" with actual reality."

Anyway I don't have more time to school you and there are so many times one can point out flawed linear assumptions. We should let it rest so you can go dig up more stats and linear assumptions for next time.

Have a nice week end.

God, what is wrong with your mind? I also posted that gender balance shifts by about 0,003 a year. So yes, it took a while for 1,05 to decrease to parity.

The longer the life expectancy, the greater proportion of women. Men are simply less viable over time.

Tiny amounts of radioactive iodine in air measured in Finnmark
Back

Published 15.08.2019

Keywords: Preparedness
Tiny amounts of radioactive iodine has been measured in air at our air filter station in Svanhovd in Northern Norway. The level detected is very low and poses no harm to people nor the environment.

The sample was taken in the period 9-12 August 2019. The measurement result is comparable to earlier measurements. Norwegian monitoring stations detect radioactive iodine about 6-8 times a year and the source is usually unknown. When no other radioactive substances than iodine is detected, the source is most likely releases from production facilities for radioactive pharmaceuticals containing iodine.

At present it is not possible to determine if the last iodine detection is linked to the accident in Arkhangelsk last week. DSA continues more frequent sampling and analysis.

"Check out the troy2c us nuclear ramjet engine from the 60s. That thing looks legit... ran at 500MW for 5 mins in a ground test. Its a shame humanity started wasting our rocket and nuclear engineer level minds after the 70s or so. I blame hippies. We could be cruising around in mach 10 nuclear business jets. "

>> let me take a wild guess.

german tech?

LOL KAPOWNED

More Russian Nuclear Monitoring Stations Went Silent Days After Blast, Test-Ban Official Says
Michael R. Gordon


The number of Russian nuclear-monitoring stations that have gone silent has doubled to four, an international arms-control official said, heightening concerns among observers that Russia is attempting to conceal evidence from an explosion at a missile-test site this month.

Russia monitoring stations designed to detect nuclear radiation at the towns of Bilibino and Zalesovo stopped transmitting data on Aug. 13, Lassina Zerbo, the executive director of the Comprehensive Nuclear Test Ban Organization, told The Wall Street Journal on Monday.

Those data disruptions occurred three days after two other monitoring stations, at Dubna and Kirov, which were closer to the site of the Aug. 8 accident, went silent, as the Journal reported on Sunday.

“Experts continue to reach out to our collaborators in Russia to resume operations as expediently as possible,” Mr. Zerbo wrote in an email.


The U.S. and other world powers have a variety of means to monitor military tests in Russia as well as Moscow’s compliance with the Comprehensive Nuclear Test Ban Treaty, which prohibits nuclear tests globally.

In addition to American spy satellites and the ability to intercept communications, there are hundreds of monitoring stations around the world that measure seismic shifts, sound waves and radioactive particles.

But nuclear experts widely see the interruption in the data from the four monitoring stations as the Kremlin’s attempt to minimize information about the weapon that was being tested, which President Trump has said is a nuclear-powered cruise missile. Experts said they don’t believe the device was carrying a nuclear warhead or that Russia’s aim in suspending the data transmissions was to hide any clandestine nuclear-weapons test.

Russia may also be trying to minimize publicity about the extent of the plume from the missile-test explosion and the radioactive elements it contains.

Mr. Zerbo’s organization, which receives data from monitoring stations around the world, has projected the potential path of the plume, which it depicts as moving toward western Russia before shifting south and then spreading to the east.

Russian President Vladimir Putin asserted on Monday that there has been no spike in radiation following the incident and that experts are monitoring the situation. “There is no threat and no rise in the radiation level there,” Mr. Putin said during a press conference with French President Emmanuel Macron in France. “Preventive measures are taken so nothing unexpected happens.”

Following the blast, Russian authorities were slow in releasing information about it. A local authority briefly reported a spike in radiation levels before removing the information from its website.

Residents of the city of Severodvinsk near the blast site rushed to pharmacies after news of the incident to stock up on iodine, which protects the thyroid gland against absorbing radiation. A Russian news outlet, Baza, published a video showing ambulances said to be transporting victims to Moscow, with the vehicles’ doors sealed in film and drivers wearing hazmat suits.

The four Russian monitoring stations that have stopped transmitting data are what Mr. Zerbo’s organization calls radionuclide sites that detect radioactive particles. They extend from Dubna, which is north of Moscow, to Zalesovo in Siberia to Bilibino in the Russian northeastern region of Chukotka, near Alaska.

Russian officials initially told the Comprehensive Nuclear Test Ban Treaty Organization that the sites that stopped transmitting were hampered by “communication and network issues.” They haven’t told the group when they expect them to be operational again.

Officials at the Russian Embassy in Washington referred questions to authorities in Moscow, who didn’t respond.

A Russian monitoring station that detects radiation at Ussuriysk—located in Russia’s Far East near Vladivostok—still transmits data, said Mr. Zerbo, who has declined to speculate on the reasons for the interruption.

The loss of data comes as the future of arms control agreements is in flux, including that of the Comprehensive Nuclear Test Ban Treaty.

That accord has been signed by 184 nations. It has yet to formally take effect because the required number of nations haven’t ratified it.

Russia, which has signed and ratified the accord, insists it is rigorously adhering to the treaty. The U.S. signed the treaty during the Clinton administration. The accord was never approved by the Senate, but the U.S. hasn’t conducted a nuclear test since 1992.

While the accord isn’t legally in force, the global network of monitoring stations, which would be used to verify compliance, is functioning and funneling data to Mr. Zerbo’s organization, which shares it with signatories to the treaty.

Steve Andreasen, who was the top National Security Council official on arms control during the Clinton administration, said that the system for monitoring adherence consisted of four different technologies, was international in scope and didn’t depend on the “good faith” of an individual country to continuously provide data.

“In the case of the Russia nuclear accident in August, two of these four technologies—seismic and infrasound—reportedly detected the explosion and reported it promptly,” he said.

Opponents of the treaty complained that the loss of data meant that Russia had simply switched off the monitoring stations. They noted that U.S. intelligence has previously alleged Moscow had violated its commitment by conducting nuclear tests with very low explosive power.

“The Comprehensive Nuclear Test Ban Treaty doesn’t serve U.S. national interests,” Sen. Tom Cotton (R., Ark.) said. “President Trump should unsign the treaty and end this charade.”

So apparently the doctors treating three of the victims were contaminated with caesium 137 - that's a fission product. So the reactor might have been active or at least have previously been active.

This is why I would generally expect these missiles to fly down range before activating in real circumstances.

It seems to indicate that the current reactor does have an on-off function.

Over to something completely different:

On/off would be pretty easy - just control rod - and makes sense for a test unit.

The real one you'd only need to turn on. Preferably at some distance :-)

I guess from this we can conclude it's actually very similar to the American design.

If I was going totally blue skies, I'd use a molten salt reactor which you could arrange to go critical only when operating at high speed and temp.

But then I guess building an entirely new reactor concept is longer than making a solid state fast reactor but small.

Well, you would need shielding for on-off. It make sense if the heat-up time is longer than the booster burn-off time.

The US design was Raver type (Serenity reference).

A totally new reactor fits the pet project theory. But we may not be seeing a new reactor right now as the design is in testing and could be using a placeholder reactor.

Not necessarily - and a fast reactor wouldn't have a time much longer than fossil fuel world keep it aloft.

I think the pet project is nuclear engine for space launch. The fallout becomes less of an issue then as if you can get the time to orbit below the degradation time of the fuel elements you might keep leakage to acceptable levels.

Any cruise missile will be a reaver type weapon just because there's no military value in increasing design constraints, cost and complexity to get safety features for the enemy population you are targeting with nukes.


Anyway, this is interesting:

Do physics allow? An airbreathing engine of any type would need a lot of momentum to push through to leo.

I am firmly convinced its a pet project. I am just not sure what kind of pet project it is.

A fission core carrying shielding and propelant only has an Isp a little better than chemical i think. Using it for only early boost phase helps... but not decisively.

Get up up high speed and altitude (that's where most energy is lost), then use onboard reaction mass, either rocket or maybe you can use chemically inert reaction mass heated by the nuclear engine.

No shielding at all. At least unless it's humongous. This would be unmanned until the technology matured (if it ever did).

The benefit of a nuclear air breathing first stage is that for the hardest part (launch to upper atmosphere) where air resistance is greatest, you don't need to carry all that fuel. The gearing on the rocket equation is brutal, so if you look at an rocket destined for LEO, something like 50-70% (I forget the exact figure but in sure it can be googled) of the fuel and weight on the launchpad is consumed just there to get the thing to the kinds of speeds and altitudes you might reach with an air breathing scram jet.

Hence things like skylon/sabre engine.

You get much better payload fraction than the rocket equation would normally allow.

Even better if you can use the nuclear core plus reaction mass instead of a chemical rocket as you don't need to carry oxidant and the extra hardware another engine entails.

It's a compelling idea, were it not for the fact it is pretty lethal and vet hard to build safely.
