2nereeney Technical Scecification Change Recuest No. 59, knendment A The licensee requests that the attached revised page replace page 3-22 of the Technical Specifications, Appendix A.
Reasons for Protosed Chance Amend =ent A to Technical Specification Change Request No. 59 vill delete the Section 3.3.2 expiration date of the proposed change and vill revise those portions of the TMI-1 Technical Specifications, Section 3.3.2, to allow an ECCS component to be removed from service such that the affected system train may be inoperable for 72 consecutive hours. This change is recuested in order to perform the necessary Decay Heat Removal Pump inspections and subsequent repairs, if needed, during power operatien.
Safety Evaluation Justifying Chance This change request does not increase the probability of any accident analyzed in the FSAR in that the time limits for maintenance of these ec=ponents as stated in the bases, has always been 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />.
This change could not increase the consequences of the only accident of concern namely a Loss of Coolant Accident (LOCA) since at least ene LPI system is demonstrated operable prior to taking the back up LPI system out of service. The operabity demonstration assure that a single failure will not affect the remaining LPI system during the 72 hour8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> exposure period.
This change does not create the possibility of occurrence of any unanalyzed accidents since no new mode of operation is contemplated or permitted. Only the exposure period with reduced redundancy is extended.
The bases for TMI-1 Technical Specification, Section 3.3, states, "An allowable maintenance period of up to 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br /> may be utilized if the operability of equipment recundant to that removed from service is demonstrated i= mediately prior to removal".
Because this change is consistent with the existing bases it does not reduce the margin of safety defined in the technical specification bases.
For the reasons given above, this change does not represent any undue risk to the health and safety of the public or an unreviewed safety question.
