This was an administrative change that did not affect the control functions, data collection, or reporting requirements of the system. Therefore, an unreviewed safety question does not exist.
9my Monthly Operating Report No. 93-05 Page 12 of 19 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: May, 1993 TM S2-93-31 Temporary Modification 05-13-93 (Safety Evaluation No.93-113)
Temporary Modification S2-93-31 installed a temporary 120 volt AC power strip from the radiation monitor cabinet 2-1 power supply to radiation monitor cabinet 2-2.
This modification returned cabinet 2-2 to service following the failure of its Sola transformer. This alignment does not constitute any additional emergency bus loading since both cabinets are normally powered from the 2H1 -1 motor control center. Therefore, an unreviewed safety question does not exist.
TM S1-93-06 Temporary Modification 05-22-93 (Safety Evaluation No.93-115)
Temporary Modification S1-93-06 installed temporary blind flanges and pipe supports to facilitate the replacement of service water system strainer 1-VS-S-1A and valves 1-SW-301 and 1-SW-302.
The blind flanges met the criteria for the piping class for which they were used and an in-service leak test was performed to verify the adequacy of their installation. The applicable Technical Specification limiting conditions for operation were adhered to during this activity. Therefore, an unreviewed safety question does not exist.
TM S2-93-32 Temporary Modification 05-24-93 (Safety Evaluation No.93-117)
Temporary Modification S2-93-32 removed a control fuse to prevent a spurious Unit 2 Hi Hi Consequence Limiting Safeguards (CLS) train B signal while trouble shooting to identify a DC ground.

TM S2-93-33 Temporary Modification 05-24-93 (Safety Evaluation No.93-116)
Temporary Modification S2-93-32 de-terminated an electrical lead to prevent a spurious Unit 2 Hi Consequence Limiting Safeguards (CLS) train B safety injection (SI) actuation signal while trouble shooting to identify a DC ground.
This modification affected only the Hi CLS train B. The Hi CLS train A remained capable of performing its design function. Technical Specification action statements were adhered to during this activity. Therefore, an unreviewed safety question does not exist.
.urry Monthly Operating Report No. 93-05 Page 13 of 19 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: May, 1993 TM S1-93-07 Temporary Modification 05-25-93 (Safety Evaluation No.93-119)
Temporary Modification S1-93-07 installed a temporary ventilation duct and configured dampers to redirect cooling air from the Protective Clothing Issue and Dressing area to supply cooling air to the Health Physics Count Room. This modification will remain in place until repairs can be made to the air conditioner (1-VS-AC-3) that normally supplies the Health Physics Count Room.
This modification will improve the reliability of the radiation monitoring equipment used in post accident analysis (while 1-VS-AC-3 is out of service) and will not affect any safety-related systems or components. Therefore, an unreviewed safety question does not exist.
Engineering Work Request 90-275 installed a manually operate.d drain valve in Unit 1 waste gas system pipe spool 2"-GW-24-154.
This modification provides a means for draining accumulated condensate downstream of relief valve 01-RV-GW-103. This will improve the reliability of the relief valve since an accumulation of condensate could impair its operation (through corrosion) and increase the potential for water hammer upon valve actuation. This change does not affect the function or performance characteristics of the waste gas system. Therefore, an unreviewed safety question does not exist.
erry Monthly Operating Report No. 93-05 Page 14 of 19 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: May, 1993 SE 93-109 Safety Evaluation 05-04-93 Safety Evaluation 93-109 assessed continued operation of Units 1 and 2 with the containment sump sampling capability of the high radiation sampling sink (HRSS) out of service.
- The assessment concluded that the Emergency Response Procedures provide alternate methods for making core damage assessments. In addition, the HRSS containment sump sampling capability is not assumed in the basis for any Technical Specification. Therefore, an unreviewed safety question does not exist.
2-0P-5.1.5 Operating Procedure 05-05-93 (Safety Evaluation No.93-103)
Operating Procedure 2-0P-5.1.5, "Venting the PRT," was revised to provide direction for continuously venting the Unit 2 pressurizer relief tank (PRT) to the containment atmosphere via PRT pressure transmitter PT-2472. This change was made in order to maintain PRT pressure low and to allow stabilization of pressurizer safety and power operated relief valve tailpipe conditions.
The containment atmosphere will be monitored by the containment particulate and gaseous radiation monitors during the venting process. Activity samples will be obtained every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and weekly grab samples will be obtained on a weekly basis in the event these monitors become inoperable. The venting process will be performed at a slow rate and will be terminated if the containment radiation monitors alarm or if samples indicate adverse (explosive) gas concentrations. The release of the PRT contents to the containment atmosphere does not pose any design or operational concerns and has no impact on the UFSAR accident analyses. Therefore, an unreviewed safety question does not exist.
1-0P-5.1.5 Operating Procedure 05-11-93 (Safety Evaluation No.93-112)
Operating Procedure 1-0P-5.1.5, "Venting the PRT," was revised to provide direction for continuously venting the Unit 1 pressurizer relief tank (PRT) to the containment atmosphere via PRT pressure transmitter PT-1472. This change was made in order to maintain PRT pressure low and to allow stabilization of pressurizer safety and power operated relief valve tailpipe conditions.
The containment atmosphere will be monitored by the containment particulate and gaseous radiation monitors during the venting process. Activity samples will be obtained every 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> and weekly grab samples will be obtained on a weekly basis in the event these monitors become inoperable. The venting process will be performed at a slow rate and will be terminated if the containment radiation monitors alarm or if samples indicate adverse (explosive) gas concentrations. The release of the PRT contents to the containment atmosphere does not pose any design or operational concerns and has no impact on the UFSAR accident analyses. Therefore, an unreviewed safety question does not exist.
9my Monthly Operating Report No. 93-05 Page 15 of 19 PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/VEAR: May, 1993 1-PT-17.7 Periodic Test Procedure 05-14-93 (Safety Evaluation No.93-114)
Periodic Test Procedure 1-PT-17.7, "Recirculating Spray HX Service Water Radiation Monitor Pump Test," was temporarily changed to install electrical jumpers to allow the consequence limiting safeguards (CLS) automatic start features of Unit 1 recirculating spray heat exchanger service water radiation monitor sample pumps 1-SW-P-SA, 1-SW-P-58, 1-SW-P-SC, and 1-SW-P-5D to be tested.
Installation of the electrical jumpers will not affect other systems or components.
The applicable Emergency Operating Procedures (EOP) will be revised to require verification that the subject pumps have automatically started upon receipt of a Hi
.Hi CLS signal. The EOPs will also direct appropriate actions to minimize the potential for a radioactive release in the event the pumps do not start. Therefore, an unreviewed safety question does not exist.
O-ECM-1403-01 Electrical Corrective Maintenance Procedure 05-27-93 (Safety Evaluation No.93-121)
Electrical Corrective Maintenance Procedure O-ECM-1403-01, "RCP Motor Disconnect and Connect," was revised to provide instructions for implementing temporary modifications to defeat the Units 1 and 2 reactor coolant pump (RCP) breaker interlocks. These modifications are needed to facilitate the performance of an uncoupled RCP motor run without relying on bearing lift oil pressure switches and loop stop valve position.
The breaker interlocks that are defeated by this procedure are not needed during an uncoupled RCP motor run since there is no flow path requirements. The performance of this procedure will not affect the reactor coolant system and does not affect other accident mitigating equipment. Therefore, an unreviewed safety question does not exist.
