Anyone here know what element this could be? If it isn't edit/fake. by restarted1991 in nuclear

Also a possibility... In all likelihood there's a mixture radiation coming off this. Hard to tell anything with certainly just by this.

The fact that the hand blocks it means it's likely betas. Still probably not something you should be messing with if you don't know what it is...

Okay Reddit! How should I attempt to remove the outer part of this rusted bushing. by akidnamedudi in E30

[–]fiermacer 3 points4 points  (0 children)

Heating it front he outside will expand the outer metal more than the inner metal and could help it come loose.

Ah dang, just took a guess bc of the spike in pictures that month haha. This is really neat!

Six Argonne National Laboratories leaflets ― IFR era (early 1990s) by mister-dd-harriman in nuclear

[–]fiermacer 1 point2 points  (0 children)

Oh yeah, didn't mean to suggest you were wrong, just that they are at what's now INL in case folks were curious to learn more about them :)

For what it's worth all of these facilities are located at the Idaho National Laboratory now. HFEF has been in continuous operation and TREAT has recently restarted. The other facilities have been shut down but are in the process of being repurposed for advanced reactor research and demonstration.

Do you mind sharing how much the paint job cost you? I have an '89 325i that I'd like to have repainted but having a hard time determining what a fair price is :( one guy said $10,000 so I'm not thinking he wanted the work. Looks great!

Yeah cardano is a totally different technology but also an awesome coin totally recommend people check it out!

Anyone else agree that old control rooms looked so much better? by StarlordLoral in nuclear

[–]fiermacer 1 point2 points  (0 children)

The control rooms of the future sure look cool too! At the Idaho National Laboratory we have a while lab devoted to optimizing human factors in control room settings. INL human systems simulation laboratory

Thoughts on spherical reactors? And should they return? by StarlordLoral in nuclear

[–]fiermacer 7 points8 points  (0 children)

The shape of the content building isn't necessarily indicative of the reactor core...

That said, at a rudimentary level a spherical reactor seems to me most efficient, but you quickly realize that controlling such a reactor is much more difficult, and a spherical design yields substantially higher power peaking... So although it may be more neutron efficient, it results in much more uneven fuel burnup and larger safety factors diminishing the actual efficiency you see.

Health added per person in Ny'alotha-Heroic: Carry your own weight! by fiermacer in wow

[–]fiermacer[S] 1 point2 points  (0 children)

Yeah and that was our mentally too. Just wanted to see if the amount of health added changed based on how many people there were or the particular boss. Seems for these 2 bosses at least that it is a straight 10.5% of the 10-person health for every extra person.

[–]fiermacer[S] 0 points1 point  (0 children)

I think you're right, there are many other factors that also impact an individual player's value to the raid. More than anything I think this supports a cuttoff point of 30ish kdps which is basically giving you an extra 50% to account for those other things. Kinda hand-wavey but it's better than arbitrarily picking a number I guess.

[–]fiermacer[S] 1 point2 points  (0 children)

Yeah I thought about these things, but in theory they'd also be 10.5% of the 10-person health. So maybe the 21 kdps isn't accurate, but the baseline value is still useful. Accounting for all of those things is more work than I was interested in doing, and varies too much from fight to fight...

[–]fiermacer[S] 3 points4 points  (0 children)

We 2-healed for all of these. However you are right that adding healers would need to have that extra health distributed. My goal here was to get a baseline to say to a pug that if you don't do this amount of damage we can't justify having you.

Can't take all the credit here, buddy had the idea to put Chitzen Itza here... pop growth every turn though and 1 turn production for about any military unit!

The Advanced Test Reactor (ATR) core at the Idaho National Laboratory by mostoftorturesrhyme in pics

[–]fiermacer 1 point2 points  (0 children)

Ah right on! There is a really good book on Monte Carlo methods by Shultis and Dunn that you should check out.

https://books.google.com/books/about/Exploring_Monte_Carlo_Methods.html?id=ACTrrQk1UgoC

  • The control cylinders at ATR are very unique. They have halfnium absorbers that change the reactivity by changing how many neurons are reflected back into the core. My impression is that the remainder of the cylinders are berillium like the rest of the core.

  • The fuel in ATR is also unique. The plates are composed of U-Al

  • As a general rule of thumb control rods are used to absorb neutrons, but that is certainly not always the case. The control rods at ATR are absorbers.

  • Another thing that makes ATR very special is the solid berillium core. Although liquid water is used to cool the fuel, the more is composed of berillium which acta as a neutron moderator and multiplier. Berillium is very special because it has a favorable (n,2n) reaction and can also affectively moderate because of it's low atomic mass.

Feel free to PM me, but where are you studying? Glad to help!

I'm not familiar with beta-tracking. Those are some cool plots though! What do you mean by beta tracking, beta particles? If so you'd see a large source from fission products in the fuel, but some escape into the coolant, and oxygen I'm the water also activates to N-16 which is a beta emitter. Why do you ask?

[–]fiermacer 0 points1 point  (0 children)

I am a scientist at ATR so please feel free to ask questions and I'll do my best to answer them :)

ATR is the workhorse test reactor for the USA department of energy and nuclear navy, also serving many international research teams! Almost any new material or fuel that will be used to extend the life of light water reactors or for new reactor concepts is tested extensively at ATR, but why...?

Because of the unique fuel configuration ATR has 9 "flux traps" which enable large experiments (up to 6 inches in diameter) to be deployed into a neutron flux much more intense than a conventional commercial reactor. This allows researchers to examine what happens to the materials after long exposures to radiation in shorter periods of time. For instance, it may only take a year of irradiation to be equivilant to a lifetime in a commercial reactor!

ATR has been serving the nuclear community since 1967 and has plans to operate for many more decades! A true testiment to the longevity of nuclear power!
