'EACTOR COOLANT SYSTEM BASES 3.4.4.11 RELIEP VALVES The power operated relief valves (PORVs) operate to relieve RCS pressure below the setting of the pressurizer code safety valves
~
These relief valves have remotely operated block valves to provide a positive shutoff capability should the relief valve become inoperable.
The electrical power for both the relief valves and the block valves is supplied from an emergency power source to ensure the ability to seal this possible RCS leakage path.
3.4.4.12 REACTOR COOLANT VENT SYSTEM The Reactor Coolant Vent System is provided to exhaust noncondensible gases and/or steam from the primary system that could inhibit natural circulation core cooling. It has been designed to vent a volume of Hydrogen approximately equal to one-half of the Reactor Coolant System volume in one hour at system design pressure and temperature.
The Reactor Coolant Vent System is comprised of the Reactor Vessel head vent system and the pressurizer steam space vent system.
Each of these subsystems consists of a single line containing a comaon manual isolation valve inside containment, splitting into two parallel flow paths.
Each flow path provides the design basis venting capacity and contains two IE DC powered solenoid isolation valves, which willfail closed'his valve configuration/redundancy serves to minimize the probability of inadvertent or irreversible actuation while ensuring that a single failure of a reaately-operated vent valve, power supply, or control system does not prevent isolation of the vent path.
The pressurizer steam space vent is independent of the PORVs and safety valves and is specifically designed to exhaust gases from the pressurizer in a very high radiation enviroaaent.
In addition, the OPERABILITY of one Reactor Vessel head vent path and one Pressurizer steam space vent path will ensure that the capability exists to perform this venting function.
The function, capabilities, and testing requirements of the Reactor Coolant Vent System are consistent with the requirements of Item II.B.1 of NUREG&737, "Clarification of TMI Action Plan Requirement,"
November 1980.
The minimum required systems to meet the Specification and not enter into an action statement are one vent path from the Reactor Vessel head and one vent path from the Pressurizer steam space.
