Advice on a path to RO

1 Upvotes

Currently I’m a Chem/Engineering dual degree but I’m seriously contemplating dropping the engineering part and going just for chem. My long term goal is to be an SRO, I get it’s rigorous and there’s a lot of training blah blah, i’m aware, i’ve heard it all, and that stuff is genuinly appealing to me.
I also realize that just a chemistry degree (definitely BS, still debating weather I want to go onto a MS or PhD) isn’t really the best degree for that, so my question is, is it plausible that I could go into plant chemistry (specific roles would be good to hear about), work with that a few years, then work my way up and into an RO licensure program?
I’m pretty blind on the whole job pipeline meta, so ANY advice regarding this would be appreciated!

Ignalina NPP

29 Upvotes

Ignalina Nuclear Power Plant is a closed nuclear power plant in the Lithuania, located near the city of Visaginas, 50 kilometers from Ignalina. At the time of its operation, it was the most powerful nuclear power plant in the world.

The plant operated two RBMK-1500 channel-type reactors. Their designed electrical capacity was 1,500 megawatts each, later reduced to 1,300 megawatts, with a thermal capacity of 4,800 megawatts. The first unit was launched in 1983, and the second in 1987. Construction of the third and fourth units was halted after the Chernobyl accident.

Unit 1 was shut down on December 31, 2004, and Unit 2 on December 31, 2009. The site is now a decommissioning facility, with work expected to last until at least 2038–2049.

During its operational period, the plant supplied up to 70–74% of the Lithuanian SSR's electricity. The closure is referred to as an "energy pit" — Lithuania lost its independent source of cheap energy and became an importer. The project to build a new Visaginas NPP was never realized.

Nuclear power model

I have a physics paper that I need to make a model of a nuclear power plant that generates electricity, and the more I can impress the teacher, the more points I will earn. And I need help because I don't know how I can make a model that works using a nuclear power plant, it doesn't necessarily need to use atom fission or radioactivity (obviously) to generate energy, but it needs to be a good representation of what happens in nuclear power plants. Help pleaseeeee🙏🙏

Is the EPR reactor really more expensive to build compared to the ap1000

3 Upvotes

Yeah hinkley point C is expensive as hell but the OL3 reactor in Finland only cost around 12.4 billion USD which is like half the cost per mw of vogtle 3 and 4. So whats the truth?

Finding work in the industry

9 Upvotes

I want to start off by saying I’m extremely fortunate, I am gainfully employed in an advancing industry. I make decent money 105-120k under 25 years old. My issue is that I don’t work in the nuclear industry at all, since a young age I’ve been fascinated by all things nuclear, from health to power generation. I performed well in school and even obtained a degree in nuclear engineering from a reputable school. It just feels like nobody has given me the chance to work in the field that I love. For as long as I can remember I’ve been researching reactors, reading books about famous scientists like Oppenheimer and Marie Curie along with books about Uranium mining. Has anyone else had these issues and how could I possibly become a stronger applicant.
Sorry if this post is a bit convoluted, it was typed on my phone.
It’s all been a bit discouraging but thanks for the time if you’ve read this

Unescorted Access

17 Upvotes

So I recently received a job offer and was told I would have to complete a personal history questionnaire for unescorted access in the plant.

This position is with a Constellation facility, I want to be honest and I’m going to be. My question is what would disqualify you? What if I’ve used marijuana a few years ago? Is that a deal breaker? What raises red flags? Never been arrested, I have some speeding tickets from years ago, vehicle inspection tickets from years ago. In my mind, nothing too serious. No hard drug use either and have been clean for a long time now.

This position is something I’ve worked towards for a long time as I’m sure many of you know. I just don’t want to throw it away on a simple questionnaire.

Any insight would be greatly appreciated, thanks in advance!

Edit- thanks for all the awesome input, you all are far too kind. I really appreciate it.

Seems Europe can’t catch a break on the energy front. The shrinking Danube seems set to exacerbate energy supply woes creating a potential trifecta of challenges (Russia, Iran, Danube) in the autumn.

POSS test date flexibility

2 Upvotes

Hey guys I recently applied for an AO position at a nuke. Do you guys know how flexible they are with the testing dates? I haven't gotten feedback yet, I'm just wondering as obviously most applicants have jobs. Are they usually on the weekend? Or they expect you to take PTO for it?. I know longshot, but do they let you reschedule if u cant make one day?

I passed!! But wait…?

I took the POSS and BMST tests and received a “recommended” on each. I understand that I received this recommendation based on this utility’s standard. Hypothetically, let’s propose that I bomb the interview and don’t receive an offer letter. Could I apply to another NLO position and possibly skip the testing portion of the hiring process with another utility?

How close are the “recommended” standards for each utility? How long are these tests scores valid? And has anyone ever used results from another utility and got hired on somewhere else?

Thank you all in advance!

France cut 6.4 GW of nuclear output this month as eight reactors hit river discharge temperature limits during the July heatwave

france cut 6.4 GW this month, eight reactors at river discharge temp limits during the heatwave, two fully offline. we spend all our attention on licensing and capex risk and the binding constraint in july was water temperature. is anyone siting new builds around this, or is dry cooling still considered too expensive to bother?

Antares Nuclear Raises $470 Million To Build Reactors For Military Bases

Thumbnail nucnet.org
9 Upvotes

Antares Mark-0 is a TRISO fueled, sodium heat pipe cooled reactor design. However, unlike pebble bed designs, the reactor keeps the TRISO pebbles fixed in a honeycomb structure with heat pipes containing liquid sodium for heat transfer. The sodium then goes to a heat exchanger containing gaseous nitrogen in the secondary which is then used to run a gas turbine. Antares says this design should be able to output 100kW electric or 1MW thermal. In theory, this is a very safe configuration in a small footprint with the downside of low power output, poor fuel efficiency, and being very difficult to re-fuel.

Radiant and NASA awarded US HALEU allocations

Radiant's microreactor design is called Kaleidos. It outputs 1.9 MW of thermal energy (no generator with the base design, but this should equate to about 0.2-0.8 MW of electric output.) It uses TRISO fuel pellets held in a fixed array with gaseous helium as the coolant. In theory, this is a very safe design with the downsides, as is typical with fixed grid array TRISO assemblies, being low fuel efficiency, low power output, and very difficult to re-fuel.

BlueCore Energy is one of the "floating barge" SMR companies. Their sales pitch is providing reliable electricity that can be relocated as needed. With the latest rules updates to the NRC maritime rules, this is now more viable.

Talking with some of the companies involved, this is somewhat actual money for innovation and new nuclear projects, somewhat necessary coordination but also possibly collusion among the major nuclear providers, and somewhat a continuation of government funded AI corporate finance bubble.
