The essential servioe water system （SEC） is the DC water heat transport system from nuclear island to sea. SEC is the safety related system, which must operate in long- term stability, security and reliable status. The pump-stop water hammer of SEC system is calculated with numerical simttlation and the applicabiliW of water hammer protection measures, such as air valve, one--way surge tank and slow close check valve, is analyzed in SEC system.
