SUBJECT:
TECHt;ICAL SPECIFICATI0tl CHANGES REGARDING LOW PRESSURE COOLANT If4JECTI0fi (LPCI) SYSTEM M03IFICATIO:.5 - BROWr;5 FERRY, UNITS 1 & 2 (TACS 12330 and 12331) In accordance with your request per TACS 12330 and 12331, we have reviewed the Tennessee Valley Authority's proposed changes to the Technical Specifi-cations for the Browns Ferry Nuclear Plant, Units 1 and 2, regarding the removal of the low pressure coolant injection (LPCI) loop selection logic. Since the logic has been removed, there is no longer the need for surveillance requirements relating to this logic nor the need to limit the variation in recirculation pump speeds for purposes associated with this logic. However, during our review, the RSB has advised us that there may be other factors which require limits placed on the variation of recirculation pump speeds such as unbalanced core flow and core and pump vibration. Further investigation into this area may be warranted. Based on our review, we find the Electrical, Instrumentation, and Control aspects of the proposed changes to the Technical Specifications to be acceptable. Our safety evaluation is enclosed. 0;YA-- G. Lainas, Chief j Plant Systems Branch Division of Operating Reactors
