선진 핵연료주기 시설(AFC)의 부식건전성 조사, 분석

Abstract

(Received September 27, 2012; Revised December 12, 2012; Accepted December 12, 2012)The amount of spent fuel from nuclear power plants has been increasing. An effective management plan of thespent fuel becomes a critical issue, because the storage capacity of each plant will reach its storage limit ina few years. The volume of high toxic spent fuel can be reduced through a fuel processing. Advanced FuelCycle (AFC) system is considered to be one of the options to reduce the toxicity and volume of the spent fuel.It is necessary to set up a test facility to demonstrate the feasibility of the process at the engineering scale.The objective of the work is a development of the safety evaluation technology for the AFC system. The evaluationtechnology of the AFC structural integrity and processes were surveyed and reviewed. Key evaluation parametersfor the main processes such as electrolytic reduction, electrorefining, and electrowinning were obtained. The surveyresults may be used for the establishment of the AFC regulatory licensing procedure. The establishment of thelicensing criteria minimizes the trials and errors of the AFC facility design. Issues taken from the survey onthe regulatory procedure and design safety features for the AFC facility provide a chance to resolve potentialissues in advance.
