Steam Generator Secondary Side Chemical Cleaning at Point Lepreau using the Siemens High Temperature Process

Abstract

The secondary sides of all four steam generators at junction with the Electric Power Research Institute the Point Lepreau Nuclear Generating Station were (EPRI). The Siemans high temperature process was cleaned during the 1995 annual outage run-down applied for the first time in North America. using the Siemans high Temperature chemical Cleaning process. Traditionally all secondary side The paper discusses experiences related to the pre chemical cleaning exercises as well as all the other and post award chemical cleaning activities, chemi-nuclear power plant stations in North America have cal cleaning application, post cleaning inspection been conducted using processes developed in con- results and waste handling activities.
