case. The primary reviewer will coordinate this review with other branches' areas of review as stated in subsection I. The primary reviewer obtains and uses such input as required to assure that this review procedure is complete. 1. The SAR is reviewed to determine that the system description delineates the main condenser system capabilities including the minimum system heat transfer and system flow requirements for normal plant and turbine bypass operation. Measures provided to prevent loss of vacuum, corrosion and/or erosion of MC tubes and components, and hydrogen buildup in the MC are 10.4.1-2 Rev. 2 - April 1981 reviewed, with particular emphasis on these measures for direct cycle (boiling water reactor) plants. System performance requirements are reviewed to determine that they satisfactorily limit possible system degra- dation conditions (e.g., leakage, partial loss of vacuum) and describe the procedures that are followed to detect and correct these conditions. The SAR is also reviewed to determine that any allowed MC system degraded operation does not have an adverse effect on the reactor primary system or secondary system in the case of pressurized water reactors. 2. The reviewer evaluates the MC system design to verify that: a. Means have been provided for detecting, controlling and correcting condenser cooling water leakage into the condensate. b. The permissible cooling water inleakage and time of operation with inleakage are provided to assure that condensate/feedwater quality can be maintained within safe limits. c. Measures have been provided to detect radioactive leakage into and out of the MC system and to preclude unacceptable accidental releases of radioactivity to the environment from the system. d. The system is provided with instrumentation and control features that determine and verify that the MC is operating in a correct mode. 3. The reviewer uses engineering judgment and the results of failure modes and effects analyses to determine that:
