Aiming at new Constructing nuclear power plants,this paper points out some potential issues and provides recommendations in review qualification of first batch of senior operators at the time of first loading.

It can evaluate and quantify the behaviors of the operators in a main control room(MCR) to a certain degree.

Based on the several past researches, a set of training ways to improve nuclear power plant operators cognitive skills is proposed With such ways, first the cognitive skills needed in the routine operation and the emergency operation are listed.

It demands operators to have high cognitive ability and correct analysis skill.

Requirements for qualification of reactor operators in nuclear safety regulations were dis- cussed in this paper.

Mental and physical health of operators of nuclear power plants (NPPs) is directly related to normal and safe operation of NPPs.

Based on the quantitative research on nuclear power plant (NPP) operator spsychological characteristics and performance, the Borda s method of fuzzy mathematicscombined with the character of operator s task is used to evaluate their abilities.

This paper describes the Chinese operator reliability experiment during the NPP operator training, which was carried out on PWR full scale simulator at Tsinghua university.
