Title: Addressing electrical power supply continuity by enhance the reliability of auxiliary power system to reactor coolant pumps after grid collapse due to natural disaster or man-made threats

Biography:

Hello, Myself Md Shamsul Huda Sohel and have to Completed my graduation in Electrical and Electronics Engineering and post-graduation in Nuclear Engineering. Presently, I works as an Assistant Engineer at Ashuganj Power Station Company limited (APSCL), which is government own largest power station in Bangladesh Under Bangladesh Power Development Board (BPDB). My carrier goal becomes to develop myself on nuclear safety and security sites. Recently, I achieved two success. My two safety & security based paper published in year 2017, one is new idea based  focus on safety & security type at International Journal of Nuclear Security (IJNS) and another is safety of RPV crack analysis at Bangladesh Academy of Sciences.

Abstract

Today’s nuclear power generation is the right example for peaceful use of nuclear energy. Generates electricity through nuclear energy become similar as fossil fuel plant except it’s heat producing method. Reactor core is that device to produce heat through controlled nuclear chain reaction and transfer them by coolant pumps. Since decay heat is sufficient to meltdown reactor core, we must be ensure to serviceable the coolant pumps continuously for overlong period after the chain reaction stopped. So, at this article just focus on long-term uninterrupted power supply to the Reactor Coolant Pumps if, all the incoming and outgoing grid towers are collapse due to natural disaster or intentionally through terrorism threats. Lack of grid supply for long period might be concerning with nuclear safety- security issue, because of towers re-construction is lengthy process and sooth to say mobile generators, UPS, battery back-up are not sufficient for yearly continuous power supply without interruption. To overcome this situation, established a diesel based peak load plant nearby or very closely with NPP and has a double capacity of coolant pumps. This diesel engines are one-tenth in total capacity and assembled them parallel. It’s because, if trouble occurs at individual unit, rest of the engines are capable to maintain the supply continuity and, whole plant not shut down. Hence, additional peak load diesel plant obviously enhance the safety of electrical auxiliary power supply system and at any nuclear power plant, it’s safety is the highest priority.
