FACIUTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR OCTOBER 1988 TM Sl-88-145 TEMPORARY MODIFICATION 10/10/88 TOP-2043 2-0P-51.5.4 An air agitator was used in the place of the mechanical agitator for mixing boric acid in the Boric Acid Batch Tank.

This does not constitute an unreviewed safety question nor does it present any safety concerns since the use of the air agitation for mixing boric acid is an acceptable alternative to the mechanical agitation.

TEMPORARY OPERATING PROCEDURE 10/10/88 Exposed resin will be flushed to demineralizer l-CH-I-3A from pipe 3"-RW-111-152 while the spent resin catch tank l-LW-TK-1 is being modified. This is to reduce radiation levels.

The procedure was reviewed for the effect on accident analyses and associated equipment operability /function.

Since this will reduce radiation levels by removing the spent resin from the pipe, an unrevie.wed safety question will not be created.

OPERATING PROCEDURE 10/10/88 This procedure allows running a charging/high head safety injection pump with service water flow isolated to both intermediate seal coolers.

and with the charging pump component cooling pump either running or shutdown.

The charging pump may run without seal cooling if the refueling water storage tank or volume control tank is used as a suction, charging pump temperatures are monitored by the P250, and the charging pump component cooling system is filled with the intermediate seal coolers isolated at least on the service water side (R WST or VCT temperatures must be kept less than 115°F to function as a source of water.)

Both units will. be in cold shutdown.

Therefore, an unreviewed safety question does not exist.

SCAFFOLDING REQUEST 10/12/88 Erection of temporary scaffolding located in Unit 2 containment to repair lights.

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability/function. Conclusion is that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

e FACIIJTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR OCTOBER 1988 2-TMOP-2013 TEMPORARY MAINTENANCE OPERATING PROCEDURE 10/13/88 AC 88-10-13 EWR 88-390 l-OP-4.1 This temporary procedure includes measures to fill 'C' reactor coolant loop; remove interlocks which prevent the opening of MOV-2595; open MOV-2595; remove t.he modification to MOV-2595 interlocks and close MOV-2595.

This TMOP is to be performed to evaluate MOV-2595 which is presently leaking excessively.

This TMOP was reviewed for any effect on accident analyses and equipment operability/function. It was concluded that probabilities of accident analyses and equipment malfunctions are not affected.

because the hot leg loop stop valve will remain closed, the unit is shut down greater than 20% ~k/k and the 1C1 reactor coolant pump is disabled and cannot be started.

ADMINISTRATIVE CONTROL 10/13/88 Administrative control was placed on valve 3-EG-15 when the valve was opened. This valve is the cross-tie between the two air bottle banks.

Since administrative control of the emergency

  • diesel generator air start bottle banks will ensure air-start circuitry redundancy, an unreviewed safety question is not created.

ENGINEERING WORK REQUEST 10/14/88 This engineering work request details the re-location of the cap screws as required. In addition, concurrence from engineering shows which caps screws may be omitted to resolve fit-up problem.

There is no impact to

  • safety from this change request. The cavity seal ring assembly will continue to perform its design function.

PROCEDURE DEVIATION 10/15/88 The manipulator crane area radiation monitor (RM-RMS-162) will be turned off to allow restoration of the containment purge with high radiation levels. High radiation levels are due to the reactor head being

  • removed. No refueling operations will be performed in this mode. Containment particulate and gas radiation monitors are fully functional.

Refueling operations will be performed, containment particulate and gas radiation monitors are fully functional and area radiation levels will be monitored locally by Operations or Health Physics personnel. Therefore, an unreviewed safety question does not exist.

PAGE 11 F ACIIJTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR OCTOBER 1988 TM-Sl-88-149 TEMPORARY MODIFICATION 10/18/88 SP-88-llA EWR 88-240 PC-DB-E/Rl This temporary modification installed a flexibie hose from 1-DG-74 to 1-CH-413 maintaining the following valves shut: MOV-1381, 1-DG-TV-108B, HCV-I522A,B,C and HCV-1523.

Since the installation will be verified for leaktightness, and the design specifications for the hose used will exceed expected pressure and temperature, possible leakage paths will be contained and possible dilution paths will be isolated.

Therefore, no unreviewed safety question is created.

SETPOINT CHANGE 10/18/88 This change provides the specific setpoints for the low temperature overpressure protection.

  • The review consisted of a RETRAN Code analysis of the heatup and cooldown of the reactor coolant system and the cold overpressurization of the reactor to prevent non-ductile pressurization or overstressing of the reactor vessel. Based on the review, the revision to the heatup and cooldown and the cold
  • overpressurization setpoint does not constitute an unreviewed safety question.

ENGINEERING WORK REQUEST 10/19/88 This engineering work request to install temporary level indicators that will be periodically monitored (2-STP-25.2A) to check service water level in service water piping to unit 2 recirculation spray heat exchanger.

A new surveillance test will be implemented which will require two temporary level gauges to monitor service water levels in service water piping to recirculation spray heat exchangers. Therefore, an unreviewed safety question is not created.

ELECTRICAL PREVENTIVE MAINTENANCE SCHEDULE 10/28/88 This deviation allowed the defeat of the automatic reactor trips by jumpering out relay contacts affecting the closed reactor trip breakers.

While the change is in effect, all power to the control rods will be physically disconnected and control rods fully inserted.

While this jumper is installed, the reactor will remain at cold shutdown with all rods inserted and all sources of power. to the control rod drive mechanisms removed. The reactor trip breakers shall be opened upon the completion of the work.

There is no method for an uncontrolled rod withdrawal with all power removed from the control rod drive mechanisms.

Therefore, this change does not represent an unreviewed safety question.

2-0P-51.5.1 e

e PROCEDURE OR METHOD OF OPERATION THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR OCTOBER 1988 PAGE 12 The charging pump cooling system will be placed in service with only 12 gpm flow through the cooler instead of 30 gpm as directed in the procedure.

It has been previously determined that even without flow to the seal coolers, charging pump seals will not be adversely affected. Therefore, 12 gpm flow will not adversely affect charging pumps and no unreviewed safety question is created. The Technical Specifications does not require operable charging pumps with both units in cold shutdown.

PAGE 15 TESTS AND EXPERIMENTS THAT DID NOT REQUIRE NRC APPROVAL 2-ST-221 l/2-ST-220 l-ST-224 MONTH/YEAR OCTOBER 1988 SPECIAL TEST 09/23/88 This special test governed the movement and placement of a weight on the straddle ring surrounding the reactor. The ring is cantilevered by design. This test provided information on behavior under hydrostatic loads.

It was determined that an unreviewed safety question does not exist because the special test had no potential to affect safety related equipment. The cavity was not flooded during performance of this test.

SPECIAL TEST 09/28/88 The special test collected data associated with the control room envelope air conditioning system. The data will be used to evaluate system performance.

The test was conducted with the system operating as described in the UFSAR and Technical Specification. Therefore, an unreviewed safety question was not created or was a Technical Specification change required.

SPECIAL TEST 10/19/88 This special test was performed to demonstrate the leak limiting capabilities of the J-seal component of the reactor cavity seal assembly.

The leakage has been evaluated and determined to be acceptable.

The change has no effect on the probability of occurrence of the accidents evaluated in the UFSAR. The consequences of the accidents discussed are not significantly increased as a result of this change.

The possibility of an accident or equipment malfunction of a different type is not created. The margin of safety as described in the basis section of the UFSAR is not reduced.
