Technical Specification Change Reouest No. 24 (Appendix A)

Replace pages 3/4 6- 5,16,17,18,19, 20 and 21 with the attached revised pages 3/4 6-1;, 16, 17, 18, 19, 20 and 21.

Proposed Change Change Specification 3/4.6.3.1 to apply to containment automatic isolation valves.

Delete the wording "during the COLD SHUTDOWN or REFUELING MODE" in Specification 4.6.3.1.2.

Add asterisks to the valves in Table 3.6-1 that perform a containment automatic isolation function upon receipt of a contair. ment isolation or radiation-high signal and add a footnote to that effect.

Reason for Proposed Change Specification 3/4.5.3.1. applies only to containment automatic isolation valves as is reflected by the surveillance requirements and this change is to clarify that point.

The requirement to demonstrate the OPERABILITY of the containment auto-matic isolation valves only during COLD SHUTDOWN or REFUELING is overly restrictive. The ACTION statement of Specification 3.6.3.1 adequately protects the health and safety of the plant personnel and the public in the event that any of the containment automatic isolation valves is found to be inoperable. In addition, this Specification could force the

~

shutdown of Crystal River - Unit 3 to perform a surveillance that can be performed in the other OPERATIONAL MODES as well as COLD SHUTDOWN and REFUELING.

The addition of asterisks and footnote in Table 3.6-1 clarifies which valves should be surveilled per Specifications 4.6.3.1.2.a and b.

Of the 103 valves listed in Sections A and B of Table 3.6-1, sixteen are check valves, fifteen do not receive a containment isolation or radiation-high signal and eight open on a containment isolation signal. The remaining sixty-four close on a containment isolation or radiation-high signal and are asterisked.

The fifteen valves that don't receive a containment isolation or radiation-high signal are:

-DHV-4 MSV-414 DHV-41 SWV-35 DHV-42 SWV-37 DHV-43 SWV-39 DHV-91 SWV-41 MSV-411 SWV-43 M SWV-45 8003050 h These valves are verified OPERABLE per Specification 4.6.1.1. Valve

'DHV-4 is included in this group, even though FSAR Table R-4 (page 5-85,

m, s

Penetration No. 344) identifies both valves on the Decay Heat Coolant letdown line inside the containment (DHV-3 and 4) as valves receiving an Engineered Safeguards signal. The valves, as originally designed, do not receive a containment isolation signal. This was reflected in the original version of Table 5-4. The " Signal" column of the table for DHV-3 and 4 was changed from " Remote Manual" to "ES" in FSAR amendment 48 in order to reflect the fact that the Automatic Closure and Interlock System logic for closing DHV-3 and4 at an RC pressure of > 284 osig comes from the ES cabinets. This System is described starting on FSAR page 9-15.

The eight valves that open on a containment isolation signal are:

BSV-3 MUV-23 BSV-4 MUV-24 DHV-5 MUV-25 DHV-6 MUV-26 These valves are verified OPERABLE per Specification 4.5.2.d.l.

Safety Analysis of Proposed Change None of the requirements applicable to the safety analysis are diminished by the proposed changes and no unreviewed safety question is involved.

This change is proposed only to bring the Technical Specifications for Crystal River Unit 3 into agreement with actual plant conditions.

CONTAINMENT SYSTEMS 3/4.6.3 CONTAINMENT ISOLATION VALVES LIMITING CONDITION FOR OPERATION 3.6.3.1 The containment automatic isolation valves specified in Table 3.6-1 shall be OPERABLE with isolation times as shown in Table 3.6-1.

APPLICABILITv- MODES 1, 2, 3 and 4.

ACTION:

With one or more of the containment automatic isolation valves (s) specified in Table 3.6-1 inoperable, either:

a. Restore the inoperable valve (s) to OPERABLE status within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />, or
b. Isolate each affected penetration within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> by use of at least one deactivated containment automatic isolation valve secured in the isolation position, or
c. Isolate each affected penetration within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> by use of at least one closed manual valve or blind flange; or
d. Be in at least HOT STANDBY within the next 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and in COLD SHUTDOWN within the following 30 hours3.472222e-4 days <br />0.00833 hours <br />4.960317e-5 weeks <br />1.1415e-5 months <br />.

SURVEILLANCE REOUIREMENTS 4.6.3.1.1 The containment automatic isolation valves specified in Table 3.6-1 shall be demonstrated. OPERABLE prior to returning the valve to service after maintenance, repair or replacement work is performed on the valve or its associated actuator, contrcl or power circuit by performance of a cycling test and verification of isolation time.

a. Verifying that on a containment isolation test signal, each containment isolation valve actuates to its isolation position.
b. Verifying that on a containment radiation-high test signal, each containment purge and exhaust automatic isolation valve actuates to its isolation position.
