just to write out some of my own opinion here.

building a nuclear reactor is costly, and have to train the employees and engineer in different section in operating the plant, even a slight flaw and something unimaginable will happen.

and i dont think we really need that much power from a nuclear reactor, even a small one, maybe is one of the reason why malaysia does not have a nuclear reactor power plant.

furthermore, the area requires to build a nuclear reactor is very big, you need to isolate the nuclear plant from the residential area, so far as i know, most of the lan in malaysia are still forest, and they are protected forest, and there are many mountain area in malaysia, so i dont think it will be an ideal place for building a nuclear reactor.

IF a nuclear reactor were built in malaysia, i bet some people will held protest about the nuclear plant and said that it is dangerous bla bla bla, and the endless debate will start
