s been designed to function as required for all modes of operation. The results of failure modes and effects analyses presented in the SAR, if any, are used in making this determination. 2. The system piping is designed to preclude hydraulic instabilities from occurring in the piping for all modes of operation. As appropriate, the reviewer evaluates the results of model tests and analyses that are relied on to verify that water hammer will not occur, or proposed tests of the installed system that are intended to verify design adequacy. Steam generators are reviewed in accordance with Branch Technical Position ASB 10-2. The feedwater control valve and controller design shall be verified to be stable and to be compatible with system(s), imposed operating conditions (e.g., control functions required, range of control and pressure drop characteristics, valve stroke, trim, etc.). Test data or operating 10.4.7-4 Rev. 3 - April 1984 experience data shall be used where available. In addition, the applicant has committed to review plant operating and maintenance procedures to assure that precautions for avoidance of steam/water hammer and water hammer occurrences have been provided. 3. The outermost containment isolation valves and all downstream piping to the nuclear steam supply system are designed in accordance with seismic Category I requirements. The review for seismic design is performed by SGEB and the review for seismic and quality group classification is per- formed by MEB as indicated in subsection I of this SRP section. 4. The CFS design is such that the plant can be safely shut down using the auxiliary feedwater system or the reactor core isolation cooling system, if required. 5. The CFS design, or other plant systems, provide the capability to detect and control leakage from the system. 6. The reviewer verifies that the essential portion of the system has been designed so that system function will be maintained as required in the event of adverse environmental
