Particle accelerator isotope separation and nova6! what has it got to do with the BOCW story

As there is a possiblilty to be links with the missions and locations from the black ops 1 campaign to the story i would like to start constructing a theory why.

Check this thread below why i think the locations and mission intel are part of the zombie story.

https://www.reddit.com/r/CODZombies/comments/j4837j/map_locations_from_thes_screens/

Currently i am looking at the project intel from mission wmd.

SUBJECT: UPDATE ON GKM ANALYSIS

Analysis of operational intelligence has shown that the Gorki-Korolev medical (GKM) Company based in Prague is being used to funnel the Soviet Chemical weapon NOVA 6 into North Vietnam and Laos using commercial cargo planes. We believe GKM to be the front company that supplied the NOVA 6 to suspected agents within U.S borders.

GKM is registered to one PAVEL GORKI, a cousin of Colonel Lev Krevchenko. The team is constructing a profile on Gorki, but we have confirmed that, following the end of WW2, he was involved in the massacre at Der Reise and the resulting standoff with American forces.

Also from the project nova intel.

(HIGH PRIORITY) Analysis of the "Uranium Club", a German nuclear energy project whose purpose was to weaponize nuclear fission technology (this project was disbanded in 1942 as a means of diverting more funds to the German war effort).

(LOW PRIORITY) Analysis of the rumored Die Glocke device (heretofore known as "The Bell") purported to be anything from an anti-gravity propulsion system to a time machine. Nothing yet can be confirmed; however a statement from Agency case office Chase Rettland details his interrogation of a low-level research assistant who claims he saw a "mirror device that allowed the viewing of images from the past". The subject of the interrogation died of unknown causes shortly after providing his statement.

Before i continue i would like to here any ideas or reasons why i maybe venturing to areas that are not worth investigating.

Thermo-plasma technology for selective 14C isotope extraction from irradiated reactor graphite - Can anyone provide a layman overview of how challenging it really is to harvest C-14? I thought isotopic separation was almost always a big challenge. Can someone contrast C-14 with Uranium enrichment? aip.scitation.org/doi/10.…

[EVENT] Laser Isotope Separation Technology

The following is a proposal submitted to the Columbian federal government by the Integrated Technical Consulting, Inc, based in Anchorage, Alaska. This proposal has been officially adopted.

A key problem for nuclear fuel reprocessing is that it inherently creates a nuclear proliferation risk. Approaches like PUREX have plutonium production baked in as a fundamental part of their design, a relic of their development during the Manhattan project.

At the direction of ITC, Inc, the Pacific Atomic Energy Agency (PAEA) will contract with Lawrence Livermore National Laboratories to develop a novel technology to solve this problem. The solution saught is based in an older idea - Atomic Vapor Laser Isotope Separation, originally designed for uranium enrichment.

ALVIS works by energizing atoms in a gas (or molecules, in the related SILEX process) with a carefully tuned laser, selectively ionizing only the desired atoms and allowing them to be redirected electrically in a traditional spectrometer-like fashion with high probability. The new technique, Advanced Laser Extraction for Nuclear waste (ALEN), applies this technique to nuclear reprocessing.

ALEN is designed to avoid reprocessing by providing no means to extract plutonium from the waste stream, instead leaving the plutonium mixed in with the other fission products from the reactor and unsuitable for use in a nuclear weapon. This can be achieved though a "black box" boosted laser system, carefully tuned to extract only uranium-235 and 238, while leaving behind all other products.

The process starts by conversion of the spent fuel into a gaseous hexaflouride mix, minimizing risk of criticality, which is then passed through a ALEN laser system several times, extracting more than 95% of the leftover uranium from the waste stream. The Uranium is then recrystallized for further use, while the fission product stream is vitrified for long term storage.

While this approach is somewhat less efficient in terms of nuclear waste required for a given mass of output fuel than a PUREX based one, as it cannot use plutonium in the output fuel, it is considerably more proliferation resistant. Development of the ALEN approach and construction of a pilot plant is expected to take 3 years, due to the existing basis in ALVIS, and is expected to cost $400 million (with an additional $300,000 going to ITC, Inc, as management overhead), with the pilot

Should the isotope separation chain in my reactor mod be done in multiple machines?

theres been a discussion about magic blocks that do everything.

my processing chain works like this:

uranium dust+pyrotheum->uranium gas

uranium gas+ aerotheum/glowstone gas+centrifuge->isotopes

should i do this with one machine, or use a separate machine for each step? or should i use a complete different chain? should i add a different fluid for each one or use nbt to distinguish?

What specific isotopic enrichment method is used to separate Pu-238 from other isotopes after U-238 decay?

I can't find a source that mentions an enrichment method used for Pu-238 from it's other isotopes. I'm not sure if i'm searching the wrong thing so any clarifications about what i should search for would be helpful. Also is molybdenum-99 enriched using the same process as Pu-238? Because i know that Mo-99 is produced is a similar manner to Pu-238 but i can't find documentation about it.

Any help will be appreciated.

Do isotope diastereoisomers actually separate on a column?

A diastereoisomer has 2 chiral centres. One has 4 different substituents (standard chiral centre), the second chiral centre has two different substituents and a deuterium and a hydrogen. Formally this centre is also a chiral centre and thus the molecule can exist as 2 diastereoisomers, but would the difference between D and H creating the second centre be enough to actually separate the diastereoisomers on a column?

Friend says absolutely yes, I say no way.

Thoughts?

(hope this question was clear, let me know if I need to explain better)
