TECHNICAL SPECIFICATION CHANGE REQUEST N0. 57 (APPENDIX A)
Replace pages 3/4 6-15, 3/4 6-17, 3/4 6-18, 3/4 6-19, 3/4 6-20 and 3/4 6-21 with the attached revised pages 3/46-15,3/46-17,3/46-18,3/46-19, 3/4 6-20, and 3/4 6-21.
Proposed Change A.
For ACTION statements b and c of Specification 3.6.3, add a footnote I to read:
"These valves may be reopened on an intermittent basis under administrative control for up to 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> in any 24-hour period as necessary for sampling or surveillance testing."
B.
Add ACTION statement e to read:
"The provisions of Specifica-tion 3.0.4 are not applicable to those valves in Table 3.6-1 annotated by double asterisks (**)."
Double asterisks have been added to appro-priate valves in Table 3.6-1.
C.
Add asterisk note to Table 3.6-1 to read:
"May be opened on an inter-mittent basis under administrative control." Asterisks have been ad-ded to appropriate valves in Table 3.6-1.
Reason for the Proposed Change A.
ACTION statements b and c of Specification 3.6.3.1 require penetra-tions with one or more inoperable isolation valves (s) to be isolated.
However, other specifications require cycling of the valves used to complete the isolation for either surveillance testing or to draw samples to complete required analyses.
It is for this reason that the footnote has been proposed.
B.
ACTION e has been proposed for Specification 3.6.3.1 for valves that, if they are inoperable and ACTION Statement b or e is in effect, are in their post-containment isolation configuration.
Since these valves are already in their post-containment isolation configuration they neither perform an emergency com cooling function, nor offer any hin-drance to normal plant operations while shut or isolated. There is no reason to restrain the entry into other OPERATIONAL MODES.
Therefore, the exception to the provisions of Specification 3.0.4 is proposed.
C.
The table note is being proposed to Table 3.6-1 because there are times in MODES 1, 2, 3 and 4 that it is necessary to cycle these manu-al valves to perfonn surveillance, draw samples, or support entry into the containment. Additionally, this note is currently included in B&W Standard (NUREG-0103, Rev. 3).
Safety Analysis of the Proposed Change A.
The footnote to ACTION statment b and c will allow the intermittent operation of the isolated valves for sampling or surveillance testing purposes under administrative control. This sampling and surveillance TSCRN57(DN89) 1749 157 80 011 50 b0
Safety Analysis of Proposed Change (Continued) testing is necessary to ensure the continued safe operation of Crystal River - Unit 3.
To prevent these activities would cause the unit to shutdown due to the failure to fulfill the other specifica-tions. This is not a reasonable course of action because the sampling and surveillance testing can be completed under administrative con-trol. This administrative control is sufficient to re-isolate these valves upon receipt of a containment isolation signal.
B.
Entry into an OPERTIONAL MODE is restricted in that the conditions of the Limiting Conditions for Operation (LCO) must be met without reli-ance on ACTION statements unless specifically excepted.
Specific ex-ceptions can be granted when the ACTION statement places the unit in a condition which is equivalent to meeting the LCO.
In this case, ACTION statement b or c will place the valves in their post-contain-ment isolation positions. Therefore, the entry into other OPERATIONAL MODES should not be prohibited because the valves will be in their isolation positions and would not contribute to an accident if con-tainment isolation was required.
C.
Intermittent operation of manual isolation valves under administrative control in MODES 1, 2, 3 and 4 is acceptable. The administrative con-trol is sufficient to re-isolate these valves upon the receipt of a containment isolation signal.
