#Didyouknow... the nuclear energy industry is one of the few industries with a security program that's regulated by the federal government.
The @NRCgov 🇺🇸holds nuclear power plants to the highest security standards of any American industry.
#NuclearPowerPlants are very robust structures that are very difficult to penetrate. The combination of these structures, a well-armed professional security force, strict access controls, & multiple backup safety systems provides layer-upon layer of safety and security.
Security measures are based on three concentric circles, with the level of security increasing as one gets closer to the reactor.
Check it out! 👇
The “owner-controlled area,” is far enough from the reactor that only minimal security is needed. Other than signs, the security measures in place aren't always visible to the public.
The “protected area” is fenced and protected by sophisticated security systems and armed security officers.
Also, at this point plant personnel must be determined to be fit for duty before they are allowed into the protected area. 👇
The innermost circle is called the “vital area.” It contains the reactor & associated safety systems, the control room, the used fuel pool, and the main security alarm stations.
Access to the vital area is limited and protected by locked and alarmed security doors.
Have you ever visited a nuclear power plant?
Let me know which one and what was your impression😀👇

Chornobyl (1986) & Fukushima (2011) are very well-known #nuclear disasters… but have you ever heard about Three Mile Island incident?
This coming May 4th many people will be talking about this event (thanks, @netflix), so let’s inform ourselves to know the FACTS about it.
Long story short:
In 1979 at Three Mile Island nuclear power plant in the USA, a cooling malfunction caused part of the core to melt in the #2 reactor. The TMI-2 reactor was destroyed.
Here’s what happened 👇
The Three Mile Island (TMI) Generating Station is a closed nuclear power plant located in Pennsylvania, USA 🇺🇸
It’s composed of 2 pressurized water reactors, TMI-1 & TMI-2, that started generating electricity in 1974 and 1978, respectively.
We know that #NuclearEnergy is one of the largest sources of zero-emissions power in the 🌎, but as any other energy-generation industry, it generates a "waste".
And I got some news for you: It is actually consider a valuable resource, not a waste!
Do you know how many bananas you need to eat to die of radiation? 😱
That's right, you can die of radiation by eating 🍌. But don't worry! I don’t actually think anyone would dare to do it.
So, here is a guide on: What to know before you go bananas about #NuclearRadiation?
In 2017 the @UofCalifornia read our minds by answering a question that we all have:
How much #radiation is too much radiation? And well, the answer is more simple than we thought 👉it’s just a bunch of bananas.
But first, we need to get familiar and understand some terms. Are you ready?
Everything is composed of atoms (Yep, the periodic table). Some of these atoms are unstable & decay or break apart, & when this happens it emits what we call #Radiation.
First of all, fuel assemblies remain submerged during all handling operations. The minimum shielding requirement is ~3m of water for a high burn-up, & they use special cranes for handling operations
Check out one of the main differences between #BWRs and #PWRs spent fuel pools👇
BWR pools are filled with demineralized water, and PWR pools are normally filled with a dilute (~0.2M) boric acid solution💧
The role of boric acid in nuclear power plant is basically to control nuclear fission rate (among other uses)
