This program provides centrols for~potentially explosive gas -
mixtures contained in the Main Condettser of fgas Treatment System. The program shall include the limit for hydrogen concentration in the Main condenser offgas Treatment system and a surveillance program to ensure the limit is maintained. Thi s limit shall be appropriate to the system's design criteria (i.e., whether or not the system is designed to withstand a hydrogen explosion) .
The provisions of sucveillance Requiremente 4.0.2 and 4.0.3 are applicable to the Explosive. Gas Monitoring Program surveillance frequencies.
