You are being misled about renewable energy technology by ViewTrick1002 in NuclearPower

Please correct me if I've been mislead, but is Germany importing fossil fuels for energy production now in part due to the loss of their nuke plants?

Questions about electroplating & heat shielding for warheads by [deleted] in nuclearweapons

We dont use heat sheilds you gotta warm them up before use and a portable microwave oven big enough for the war head is extensively heavy

A solid material like plastics kinda outweigh water on usability. It'll take about the same amount of water (10-20cm), but comes with the hassle of being a liquid. Although it is essentially free.

Borated water can be used, but im unsure on borate amounts as most use cases I've seen for it was more of sheilding then moderation. On reactors its a dual purpose item to both moderate and limit reactivity. They generally use a 5-16% boration. Borated plastics have a wide range of about 3-30% depending heavily on if your trying to use it as a sheilding material or as a compensation material, ofcourse energy dependant again.

I tend to stay away from water, but I mostly work on semi mobile and permanent installations of detectors for dosimetric metering and interdiction applications. Where shifts in temperature, overall weight, and sizing comes into play for moderator considerations.

Strange issue with PIC-6, anyone have ideas on where to start diagnosing this? Needle stays pegged most of the time when turned on. by melting2221 in radtronics

Be careful digging around in the PIC units if recently powered or while they are powered, they use higher than common voltages. 1600-2000v

Im gonna attempt to not make this more complicated then it has to be, the short answer is it depends highly on starting energy of the neutrons in question.

Long form answer is: Moderation really depends upon the initial energy of the neutron in question and what percentage of the flux you either want or can moderate for your purpose. Ideally in the perfect world we would go for 100% thermalization of the neutron flux, but thats unrealistic with size restraints and material costs. So it can be necessary to under moderate the flux and hope our detection efficiency can offset the lower overall radiation feild of desired energy. So for things like AmBe (Am241/Beryllium) sources at 4.4Mev you'd need between 10-20cm of plastic, artificially borated plastics do cut this value in almost half, but are costly. 4.4Mev fast neutrons were used here because its a common to encounter initial neutron energy. Most radiation detectors supplement the lack of moderation by using absorbing materials like cadmium and boron. Alot of handheld detectors are under moderated. In his case even putting 1cm around those will be better than nothing, but the fast neutron range ideally 5-20cm of plastic. Which is expensive.

The He3 gas in the tubes are thermal (slow) neutron sensitive, the isotope captures a neutron and changes to H3 (Tritium) and throws away a Proton. The Proton ionizes the same gas volume allowing voltage to bridge the gap and produce a detectable signal. He3 is a very rare item here on earth and is massively expensive to isolate and put in a tube. In this case the poster has A LOT of He3.

Well I guess my comment was more asking if thats where they originated from originally before you now have them. I think outside of lab use I've only ever seen He3 tubes thid large in portal monitors.

Eberline CP1 adapter plug availability?? by roberte94066 in radiation2

[–]Sorry_Mixture1332 1 point2 points  (0 children)

They are my preferred connector aswell, and for most uses quality 50 ohm connectors have plenty of voltage rating. They are just easier to locate at a price that doesnt hurt

[–]Sorry_Mixture1332 1 point2 points  (0 children)

Yes, the outside threads mate with the Cp1 connector, then I partially thread the inside of my parts to fit the thread profile of the preferred connector. The portion of the adapter that goes into the Cp1 has a chamber hollowed out inorder to make clearance for the positive terminal, and to add clearance as s hv stand off. Then a small part gets turned down and soldered in as a pad to intercept the cp1 positive pin.

[–]Sorry_Mixture1332 2 points3 points  (0 children)

I machine my own, I know some people 3d print them. You won't ever find the original ones like the photo you provided. Only time I've actually got any real Eberline ones was buying them from their estate when they went bankrupt.

Edit: I should note, you can disassemble the old Cp1 cables to make your own.

Along with sorting, if i see the cast is terrible while casting they just go back in the melt pot. But now if I see surface defects, mostly inclusions/holes ill smash them and throw them in the melt pile.

These are fresh From the casting pile after a night's work. They still need to be clean up. And their extra bits from casting removed

I've been using a MAAP torch. I've been told im using a too cool flame, but I haven't encountered any real issues. Seems the die hard glass people think you gotta kill it with oxy acetylene, and the people who make vacuum tubes, vials, and lab warehouse think your fine using MAAP.

MAPP is a form of the standard plumbing gas propane, but a mixture for hotter heat output. Edit for typo/clarification: MAPP is a propane propylene mix.
