what is a typical day like working as a armed nuclear security officer? are officers issued weapons to take home and clean etc. anyone work 12 hr shifts and works at night? how is that? thanks for the help.
Although I am not a security guard, I can speak to what my company does. Hopefully we have some actual guards that can give better data around here, but I am not aware of any.
1) No, you don't get to take your gun home. You are issued your weapons as necessary when you take the shift. You then turn them in at the end.
2) I have worked 12 hour shift work and at night, and yes it can be boring, but you'd be surprised the kooks that come out at night around remote plants. IE at my last plant, we had a guy in our substation that thought poaching deer at 2am with a high powered rifle whilst in said substation was a good idea.
3) Typically, you will stand posts in towers..., at my place, you are in there no more than 2 hours. You move around the site throughout the shift. You can also be a "tour" guard..., meaning you rove a particular space every hour or so, IE through the conrol room, checking security doors, etc. You can also be "at the ready." I can't get too specific about that, because it is safeguards info that I am not privy to, but basically there is a cadre of guards in a room just waiting to jump into action. Seems pretty boring.

You will also do miscellaneous tasks such as stand guard at a gate that ops needs to open for whatever reason, for example, or the sally port checking in trucks and what not. You may also have to provide escorts for people that don't have unescorted access.
4) As far as pay, you are typically paid a particular rate while in training, then when you "weapon up" you get a bump in pay.
I hope that helps.
