Further discussion on THINK GREEN BECAUSE NUCLEAR IS GREEN!

Allright folks, previous post got many comments, which made me so motivated to write a new post on asked questions. First of all I feel quite relieved that fellow future engineers from UNITEN agreed to the fact that NUCLEAR ENERGY is clean, green and beneficial.

There was one funny question, so the answer is, if we know an alternative source is green, why we wanna go and look into how green it is compared to other green alternatives. knowing that Nuclear Energy is green is very sufficient for us.

Talking about the safety features present in NPP which is austounding, we can see that they are protected layer by layer. Look at the pictures below, you can understand the whole safety structure of it.

Apart from this there few factors included while designing safety measures inside a NPP. They are redundancy and diversity. Redundancy means the safety system is designed such way so that safety measures or sensors placed repetatively such that if one fails, other will sense the problem and rectify it. Diversity in the other hand means, the plant does not depend only on source of solution but many. For example, if moderator inside the reactor begin to deplete, the system can supply water from normal water supply or else from spare water tank. If any one of this fails, the other can solve the problem.

Some interesting facts:

For current existing reactors: core meltdown can occur as much as 1 incident in 10,000 years.

(assuming the if the reactor works for 10000 years)

For future reactors: core meltdown can occur as much as 1 incident in 100,000 years.

(assuming the if the reactor works for 100000 years)

Aren't this facts are mindblowing? think about it!

Well, to talk about the duration of time taken for planning till commissioning takes around 9 to 10 years. to make it simple I post the picture below, it explains what was the effort by government to initiate the nuclear energy programme. Yet folks, it is subjected to changes. Take it as a reference!

I would like add something here, looking at the picture above we know that it takes nearly a decade to operate our own NPP. Talking about a decade of time, don't you feel that we have more than enough of time to learn and acquire more skills on operating a NPP? So my point here is, we don't have worry about our people's level of expertise, we just need to put trust on them, so that they learn and train themselves well enough before they are ready to operate a Nuclear Power Plant.

some quotes by 'some' people:

All the waste in a year from a nuclear power plant can be stored under a desk.
Ronald Reagan

Almost every way we make electricity today, except for the emerging renewables and nuclear, puts out CO2. And so, what we're going to have to do at a global scale, is create a new system. And so, we need energy miracles.
