Low Level Radwaste Management and processing in Maanshan NPP

摘要

Nuclear power plant like as the other power plant will generate technology waste. Owing to Nuclear still is a debatable topic for discussion, Nuclear radwaste including low level radwaste, high level spent fuel and nuclear operate safety become a focus point in Taiwan also in all world. Maanshan NPP is the only one PWR unit in Taiwan. In common understand, the Low Level radwaste generate from PWR unit is less than BWR. No matter what LLW generate quantity is reduced obviously, the government asks seriously restrain LLW quantity year by year. Maanshan NPP had reach a stable level in solidification waste, system spent resin, combustible and incombustible radwaste that generate from necessary maintenance. The further aim is keep waste generate under control, stable operate processing system and make a new processing technical to dispose spent resin. Maanshan NPP via technical cooperation to set HESS system with INER in one decade. Nowadays there are about 18 55gallon drums per year in Maanshan NPP. LLW incinerator equipment designed by Maanshan and install at 7 years ago, there almost burns up all the combustible LLW that generate from commercial operation. The new equipment, wet-oxidation solidification process for treatment of spent radioactive ion-exchange resins plan will cooperate with INER and complete in 2014. It is estimated that the generation of solidified wastes of the NPS will be reduced to about 1/3 volume of that currently generated.
