Defended my PhD in nuclear engineering
A picture of two people in front of a projector screen, which is showing the first slide of a PhD defense titled "State-Level Nuclear Fuel Cycle Simulations for International Safeguards Applications". On the right is Katie, wearing a suit and the smile of relief that comes with finishing your defense, and next to her is her advisor Paul Wilson A picture from the audience of Katie mid-presentation, pointing at the screen. On the screen is a slide showing the new nuclear material packaging capability and how it allows simulations to track individual nuclear materials of different types

Men would rather lose access to nuclear secrets than go to therapy

Hahaha yes absolutely we will!!

I think by saying "lose access to nuclear secrets" 404 was just simplifying the notion of a Q clearance. I don't think we know what he worked on or had access to specifically

Yes!! You will win a security investigation by people who don't understand silly little jokes on the internet 🤗

This is why we have to give you all regular CI awareness briefings. And some people still just don't get it.

Yeah I've heard it a bunch (from other nuclear engineers!) when people speak generically about reprocessing and reusing fuel for advanced reactors. Or even sometimes when talking about reprocessing for a specific design, e.g. Oklo which is definitely not oxide fuel

"These facts and the record convince me that the Individual is able to communicate effectively and that he is quite capable of understanding and interpreting DOE security’s rules and regulations."

Frightening thing is that it could be any one of us.

Also the clearance appeals are sometimes a wild read in general, I think my favorite is the unnamed senior official who had a decade long extramarital affair with a sensitive country foreign national and didn't bother to tell anyone

"The Individual also admitted that he had entered a Vault Type Room with his cell phone on several occasions and had failed to inform his supervisor of these breaches, as required by security procedures, because he didn't think these security breaches were important."

Not all isotopes of those elements are fissile

Before you say this doesn't matter, counterpoint: yes it does

I personally use mixed actinide as a generic form, but this isn't perfect because the acronym MA also means minor actinides (neptunium, americium, curium). Its probably better to explicitly say U-Pu or U-TRU as applicable, and the chemical form as necessary

Pedantic nuclear opinion: we need a better term for uranium-plutonium fuel than MOX, aka mixed oxide fuel. Many advanced reactor designs don't have fuel in an oxide form!

Man if the government is about to pull your clearance and ruin your livelihood bc you accidentally uploaded an enormous porn stash onto govt servers during your severe depressive episode, I would think you would at least talk to a therapist to show you're trying to get a handle on the situation????
