SER No. SPCN 85-0837 Description of Change Add NOTE to allow certain steps in the transverse incore probe (TIP) system cold checkout to be performed in test condition heatup with the reactor in cold shutdown.
Summary I. No. This procedure does not increase the probability of occurrence or the consequences of an accident or malfunction of equipment important to safety, as previously evaluated in the SAR.
II. No. See I above.
III. No. The margin of safety, as defined in the basis for any Technical Specification, is not reduced.
SER No. SPCN 85-1206 Description of Change Perform tests to determine a cause for Reactor Water Cleanup (RWCU) isolations.
Summary i I. No. The referenced test which is performed while the reactor is in Condition 4 (cold shutdown), does not cause or affect an accident which exceeds those already analyzed in the SAR.
II. No. This procedure does not create a possibility for an accident or malfunction of a different type than evaluated previously in the SAR.
III. No. The margin of safety, as defined in the basis for any Technical Specification, is not reduced.
SER No. SPCN 85-1269 Description of Change Revise criteria for reactor water cleanup tests to ensure that the cleanup return temperature is less than or equal to 436 F when the heat exchanger bypass valve is open.
Summary I. No. The probability of occurrence or the consequence of an accident or malfunction of safety related equipment as previously evaluated in the SAR is not increased by this procedure change.
II. No. See I above.
III. No. The margin of safety, as defined in the basis for any Technical Specification, is not reduced.
SER No. SPCN 85-1275 Description of Change Provide instructions to station / operating personnel for the main turbine generator initial roll and synchronization below 5% core thermal power.
Summary I. No. The operation of the turbine at low loads is a routine plant function during startups and does not affect any SAR evaluation.
II. No. See I above.
! III. No. The margin of safety, as defined in the basis for any Technical Specification, is not reduced. This is a routine operation and does not affect the margin described in the Technical Specification.

SER No. SPCN 85-1419 Description of Change Create a temporary procedure to perform an integrity test of the main generator stator cooling system.
Summary I. No. The development of this temporary procedure and the performance of this test does not affect any SAR evaluation.
II. No. Performing this test does not create a possibility for an accident of a different type than previously evaluated in the SAR.
III. No. The margin of safety, as defined in the basis for any Technical Specification, is not reduced.
SER No. SPCN 85-1532 Description of Change Add two valves to the valve lineup checklist for performing pressure testing of the Fuel Oil Transfer System piping for Emergency Diesel Generator 101.
Summary I. No. This procedure change does not increase the probability of occurrence or the consequence of an accident i
or malfunction of safety related equipment as previously
[
evaluated in the SAR.
II. No. The addition of two valves to the valve lineup l checklist does not create a possibility for an accident or malfunction of a different type than previously evaluated in the SAR.

SER Nos. SPCN 85-1540 through 85-1545 Description of Change Incorporate some of the recommendations from Revision 3lof the BWR Owners' Group Emergency Procedures Guidelines into the following plant emergency operating procedures:
SPCN No. 85-1540 Level Control 85-1541 Reactor Pressure Vessel Flooding 85-1542 Emergency Reactor Pressure Vessel Depressurization 85-1543 Level Restoration 85-1544 Containment Control 85-1545 Cooldown Summary I. No. The probability of occurrence or the consequences of an accident or malfunction of equipment important to safety, previously evaluated in the safety analysis, is not increased. These revisions deal with highly improbable event sequences which are not within the scope of the SAR.
II. No. See I above.
III. No. See I above.
SER No. SPCN 85-1667 Description of Change Incorporate changes to Test Specification 22A5727, "GE Startup Test Specification" and Mark III Program "TIPSYM".
