Yes friends, of course! Definitely we will venture into nuclear technology. Or else will be left out in the this nuclear renaissance era. I don't prefer my country to be left out. Do you?
Ok then let's look into the currentlty available GEN 3/3+ reactors. Below here is a table with the available reactors and their details:
Based on the table above, we can observe that there are ample of factors that can be considered to choose the suitable type and capacity of a reactor. As for a start I would short list the reactors based on one factor which is the reactor capacity factor. I would suggest we use nuclear reactor type with power capacity range of 1300 to 1400 MWe which are ABWR and APR 1400 (PWR).The reason behind the selection is the amount of load that will be connected through one of these reactors to the national grid system to power several areas. Whenener the Nuclear Power Plant (NPP) has to be shut down immediately, huge amount of load will be off the grid suddenly. These condition will lead many problems like damages to power equipments, tripping at many substations, and a possible situation for a blackout throughout the country. Thus the reasonable range of reactor capacity will be 1300 to 1400 MWe.

Secondly, looking into risks that present such as licensing, constructing and life-cycle costs; ABWR and APR 1400 (PWR) has relevant documents and costings. These reactors has been running currently in countries like Japan and Korea gives more advantages in term of exact amount of constructon cost and life-cycle cost. ABWR for instance provides overall good economics, where it has proven costs and scheludes in Asia and US.
Thridly, the safety measure taken to protect the NPP is high in both type of reactors. Both has 3 or 4 terrain safety system which makes breakdown and also radioactive leakage an impossible one. Besides that, upon consturction the major equipments installed on these type of NPP are made from factories and not asssembled at the construction site itself. These equipments from company has longer life and stronger compared to one which is assembled at the constuction site. Main reason behind the assembling of equipments at the site is because of unavailability of technology to commission the equipments once the containment chamber has been built. Now it is not a problem at all, these equipments can be installed using special gadjets inside the containment chamber (thick concrete wall).
Eventhough I have listed 3 advantages of these reactors, which is a Boiling Water Reactor (BWR) and a Pressurised Water Reactor (PWR), there many more areas such as the important ones; public acceptance, economic situation and future demand that we can look into before deciding the type of reactor that we are going to choose.
Although you have mention,all the advantages of the nuclear reactor,that planned to build in Malaysia,but we must also consider the bad effects,such as effect to the environment(flora and fauna).Besides that,i have a doubt on how the product of radoactive waste will be dispose,how can it be done??

hi Kesavan, it is a good and common question which arises inside everyone. kindly look at "Frequently asked questions" post. Details on radiactive wastes and how they affect the flora and fauna (in fact none) can be learned there. Thank you.
ReplyDeleteThe first (3rd generation) advanced reactors have been operating in Japan since 1996 and now they are working on the Late 3rd generation designs and they even had start to built it.But we(malaysian) are just in the first step thinking about GEN 3/3+ reactors as a suggested reactors for Malaysia.We should make a dramatic progress.vimalan me083663 vimalan_12@yahoo.com
ReplyDeleteFrom my opioan i'll agree with the pie chart. I'll choose ABWR. The ABWR is designed for a lifetime of at least 60 years, though operation beyond that 60 year point will certainly be possible unless safety limits within the expensive to replace reactor pressure vessel is reached. ABWR also not having expensive steam generators need to be replaced, either, decreasing total cost of operation. It also has design that is simpler, far more intuitive, and less costly to build, and less compact
