4. NINE MILE REQUIREMENTS (dynamic loads, functional requirements)

This motor-operated valve is located in the reactor building closed loop cooling water system (CCP). The functional requirement of this valve is to permit isolation of CCP flow from the spent fuel - fuel pool cooling and cleanup (SFC) heat exchanger EIA.

This valve assembly is required to withstand an acceleration value of approximately 1.5 g for SSE and 1.4 g for OBE conditions along each of the three axes together with the deadweight and valve operating loads (i.e., pressure, temperature, and torque).

5. QUALIFICATION RATIONALE The operability and structural integrity of the valve assembly was assured through an evaluation of all the parameters affecting its function. These include the temperature, pressure, deadweight, operating loads, fluid flow, piping end loads, seismic loads, and the normal and accident environmental parameters. The effects of each of these loads are discussed below.

The thermal effects are considered to be insignificant since the operating temperature range is only between 40*F and 160*F. A conservative design pressure of 720 psi was used in the analysis, which is more than the specification requirement of 200 psi. The fluid flow is 2250 gpm, i.e., about 6.5 ft/see through a 12 in.

diameter pipe, which is small and is not expected to have any effect on the ability of the valve to close. The stresses in the valve body due to the piping end loads were shown to be very small C3/12177/244/5YH

l Spic. No. P30%R (13,000 psi due to SSE) and are not considered sign:.ficant in demonstrating operability of the valve assembly.

The normal and accident environmental parameters are evalsated for all valve body nonmetallic components and the electrical motor operator, and were found acceptable.

Based on the above, it was concluded that the significant loads to be considered for operability are the deadweight, operating and seismic loads. These loads were addressed through a combination of analysis and testing.

The structural adequacy of the valve assembly was ensured through a static analysis (Reference 8).

The functional adequacy of the valve assembly is demonstrated through a combination of tests. The description of each test is as follows:

1. Static Deflection Test: This test demonstrated that there was no bending of the valve stem or any other internal components to jeopardize operability. An identical valve assembly wais also statically deflected up to 11.6 g for further ansurance of operability (References 10, 11, and 12).

2. Valve Operator Test: The motor operator's functional adequacy was demonstrated through an extensive dynamic .

testing program of similar operators. These tests con-sisted of aging, which simulated the normal plant vibra-tion, a series of single frequency tests in the seismic frequency range, and a series of random multifrequency, multiaxis, dynamic tests (References 13, 14, and 14a).

3. Preoperational and Performance Tests: These tests consist of seat leakage, hydrostatic shell, and cyclic tests of the valve assembly (References 15 and 19).

6. QUALIFICATION RESULTS The static stress analysis demonstrated the valve assembly's adequacy to a level of 5.83 g for seismic loading together with the deadweight and operating loads. The static deflection tests of the valve assembly established operability within the specified time and leakage requirements to an acceleration load of 11.6 g. The valve operator's dynamic testing program successfully demonstrated the adequacy of the operator to function to a level of 14.0 g (Reference 14a).

The valve operator's testing program indicated that modifications are required for tightening of screws within the limit switch housing and gap adjustment proceduren. These modifications are being addressed by the implementation of Reference 20 I

7. FIELD VS. QUALIFICATION MOUNTING (LATER)

REVIEWER'S CONCLUSIONS:

Based on the evaluation of all the applicable parameters, the valve's structural adequacy and functional operability were demon-strated.

The results of the seismic analysis, the valve operability tests, and the motor-operator dynamic tests show that the functional capability of the valve will be maintained during and after the seismic test.

The following programs will also be implemented to ensure oper-ability of the valve assembly:

1. As-built verification of all loading values.

2. Modifications to Limitorque operators Reference 20.

3. In-situ testing of valve assembly.
