Abstract

The possible influences to Chemical and Volume Control System design caused by coolant pump seal water distribution are discussed.The essential reason is picked out in this paper.The temperature drop of charging flow at the regenerative heat exchanger outlet is calculated,and the feasible retrofits of the Chemical and Volume Control System are illustrated.The thermal hydraulic software Flowmaster 7.5 is employed to numerically investigate the possible capability of charging pump with different coolant pump seal requirements.
