  • e Surry Monthly Operating Report No. 98-10 Page 10 of 18 FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR:

October, 1998 UFSAR Change Request (Safety Evaluation 98-095) 10/01/98 UFSAR Change Request FS98-022 contains numerous editorial changes that correct inaccuracies and clarify or enhance sections of the UFSAR pertaining to the Emergency Diesel Generation and Electrical Power systems. These changes were needed as a result of the Integrated Configuration Management Project and consist of editorial and technical changes/corrections.

Design Change Package (Safety Evaluation 98-096) 10/01/98 Design Change Package 98-040, "Recovery of RS System Spray Flows," changes the normal position, from normally open to normally closed, of various vent and drain valves associated with the Inside and Outside Recirculation Spray Heat Exchanger shell side level switches and shell side drains. The calculated flows lost through the valve created short falls in the delivered flows to the Recirculation Spray System spray rings. Although the short falls were evaluated and found acceptable, they do decrease the available flow margins for each of the Recirculation Spray System pump delivered flows. By closing the identified valves the short falls will be eliminated and the margins increased.

Design Change Package (Safety Evaluation 98-097) 10/01/98 Design Change Package 98-043, "Auxiliary Feedwater Pumps Steam Supply PCVS," modifies the Turbine Driven Auxiliary Feedwater System (TDAFWP) circuit logic so that when the pump is started by an automatic signal and then the initiating signal is cleared, the steam flow can only be stopped after the circuit is manually reset. The modification consist of installing two new auxiliary relays for each TDAFWP solenoid operating valve circuit. Design Change Package (Safety Evaluation 98-100) 10/08/98 Design Change Package 98-025, "Fuel Assembly Repair," describes the reconstitution of fuel assemblies following Unit 1 Refueling Outage. The reconstitution will allow suspect fuel assemblies to be considered for subsequent core reload designs and potentially aid in the determination of the root cause failure mechanism of the assemblies.

Safety Evaluation 10/14/98 Safety Evaluation 98-103 was performed to evaluate the Reload Safety Evaluation Technical Report and the Reload Safety Analysis Checklist for the refueling and operation of Surry Unit 1 Cycle 16. Cycle 16 will use higher enrichment (up to 4.3 w/o) reload fuel in accordance with Technical Specification Amendment Number 214. UFSAR Change Request (Safety Evaluation 98-104) 10/16/98 UFSAR Change Request FS98-040 modifies the refueling reassembly sequence as currently stated in the UFSAR to allow for easier deconning and ease of access of the reactor cavity when retensioning the reactor head studs. The new method of operation is to install the transfer tube blank flange, remove the cavity seal strong backs, and then retention the reactor vessel head studs. The UFSAR currently states that the head studs are retensioned, the cavity seal is removed, and the fuel transfer tube blank flange is then replaced.

October, 1998 Safety Evaluation 10/16/98 Safety Evaluation 98-105 evaluates the 1998 Unit 1 Refueling Outage against current industry guidelines and Virginia power administrative requirements for shutdown risk management including NUMARC 91-06 and NE Technical Report 865, Rev.3. The schedule provides a plan for safely and efficiently accomplishing refueling, maintenance, modification, and testing activities.

Temporary Modification (Safety Evaluation 98-109) 10/22/98 Temporary Modification S1-98-017 will be used to install a temporary air supply. The air supply will be used to enable the replacement of an instrument air valve without causing a sample system valve to fail closed thus preventing the ability to pump the contents of the containment sump out of containment.

The temporary air line will be installed from an instrument air valve to the inlet of a solenoid operated valve thereby enabling the valve to operate normally.

Temporary Modification (Safety Evaluation 98-110) 10/26/98 The purpose of Temporary Modification S1-98-018 is to facilitate the use of Valve Operator Testing and Evaluation System (VOTES) on a Condensate Polishing valve. The modification involves the installation of a jumper and lifting of an electrical lead. Without the modification the valve would remain open due to detection of low feedwater suction pressure.

The valve needs to be cycled as part of the VOTES testing that will be performed at cold shutdown.

Temporary Modification (Safety Evaluation 98-111) 10/29/98 The purpose of Temporary Modification S1-98-016 is to install a temporary power supply to the level transmitter for the Component Cooling Surge Tank so that it will continue to provide Unit 1 and Unit 2 operators with level indication while work is being performed in the main board rack. The main board rack being worked provides level indication for both units. Temporary Modification (Safety Evaluation 98-113) 10/30/98 The purpose of Temporary Modification S1-98-019 is to bypass the Robertshaw Fire Detection System alarm and the placement of a jumper in the affected CO2 hazard zone panels which will clear the signal from the Robertshaw Fire Detector System. This will clear the "locked in" trouble annunciator window. The modification will include the installation of jumpers. It will eliminate an operator work around to verify operability of the Robert Shaw Detection System on an hourly basis due to the "locked in" annunciator window caused by the tagout of the low pressure CO2 Fire Suppression System for the turbine and generator.

  • e PROCEDURE OR METHOD OF OPERATION CHANGES THAT Dip NOT REQUIRE NRC APPROVAL MONTHNEAR:

October, 1998 Engineering Surveillance Procedures (Safety Evaluation 93-140, Rev. 1) Surry Monthly Operating Report No. 98-11 Page 12 of 18 10/24/98 Procedures 01-NSP-CC-001, "Performance Test of Component Cooling Heat Exchanger 1-CC-E-1 A," and 1-NSP-CC-002, "Performance Test of Component Cooling Heat Exchanger 1-CC-E-1 B," were modified to temporarily connect a Rosemount delta pressure transmitter in parallel with the existing pressure instrumentation to allow data collection on the component cooling heat exchangers.

The revision to the safety evaluation was to make administrative changes to correctly reference the procedures and to include reference to the pressure rating of the tubing used in the installation.

Maintenance Operating Procedures (Safety Evaluation 94-190, Rev. 2) 10/01/98 Procedures, 1/2-MOP-EP-030&031"Removing From Service and Returning to Service of Station Batteries 1A, 18, 2A, & 28," and l/2-MOP-EP-204,205,206, & 207, for the removal from service and return to service of 4160V bus 1 H & 1 J, 480V buses 1 H, 1 H-1, 1 J, & 1 J-1, and 480V MCC 1H1-1, 1H1-2, 1J1-1, & 1J1-2 are being modified.

The modification of the procedures is to describe the plant line-up that establishes the minimum equipment required for safe operation when the DC Buses are cross tied and one battery is disconnected from the DC Bus including the "H" and "J" Emergency Bus outages. Maintenance Operating Procedures Electrical Periodic Test Procedures Electrical Corrective Maintenance Procedure (Safety Evaluation 96-047, Rev 3) 10/01/98 Procedures, 1/2-MOP-EP-030&031, "Removing From Service and Returning to Service of Station Batteries 1A, 18, 2A, & 28," and l/2-EPT-0106-01, 02, 06, & 07 "Main Station Battery (IA, lB, 2A, 2B) Refueling Service/Performance Test, and O-ECM-0104-03, "Main Station & EOG Battery Freshing Charge," are being modified.

The modification of the procedures addresses the plant line-up during the interval that the Main Station Battery leads are disconnected and the DC cross tie is open. The modification also provides for the installation of the Main Station Battery test equipment and jumpering of weak cells, to ensure that the Main Station Batteries can be removed/returned to service within the design basis as stated in the UFSAR. The procedures provide for the installation of a jumper that removes a possible spark producing activity out of the vicinity of the Main Station Battery fill and sample ports. Temporary Operating Procedure (Safety Evaluation 98-094) 10/01/98 Procedure 1-TOP-BC-4087, "Bearing Cooling Water System Makeup," is being used to demonstrate that using condensate storage tank water as Bearing Cooling system make-up instead of gland steam will eliminate ammonia and high pH levels in the Bearing Cooling System. In the event that the alternate make-up is unable to be adequate, steps are included in the procedures to ensure proper make-up is obtained by returning to the original line-up. '

  • PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID Nor REQUIRE NRC APPROVAL MONTHNEAR:

October, 1998 Periodic Test Procedure (Safety Evaluation 98-098) Surry Monthly Operating Report No. 98-11 Page 13 of 18 10/06/98 Periodic Test Procedures 1/2-PT-36, "Instrument Surveillance," are being revised to provide instructions that if the Recirculation Spray (RS) sump level is less that five inches, it should be filled to greater than six inches by placing both containment sump pumps in off and overflowing the containment sump into the RS sump. The evaluation was required because the UFSAR states that one containment sump pump is in automatic and the other is in standby. Operations Periodic Test Procedure (Safety Evaluation 98-101) 10/08/98 Operations Periodic Test Procedure O-OPT-VS-005, "Control Room Leak Test," was revised to act as a procedurally controlled temporary modification to allow the attachment and removal of an orifice plate on the ventilation duct so that the Main Control Room pressure boundary test can be run using the fan. Operations Periodic Test Procedures (Safety Evaluation 98-102) 10/08/98 Operations Periodic Test Procedures 1/2-0PT-ZZ-002, "ESF Actuation With Undervoltage and Degraded Voltage 1 J/2J Bus," were revised to allow functional testing of the auxiliary ventilation fan not connected to the shutdown unit by actually testing the fan controls originating in the shutdown unit. Previous testing of controls was done with the power supply swapped from the operating unit to "J" bus of the shutdown unit. Maintenance Operating Procedures (Safety Evaluation 98-106) 10/16/98 Maintenance Operating Procedures 1-MOP-SW-002 "Alignment of Alternate Discharge for Recirc Spray Service Water Rad Monitor Pumps," and 2-MOP-SW-002 "Alignment of Alternate Discharge for Recirc Spray Service Water Rad Monitor Pumps," were developed to include controlled temporary modifications to route the discharge of the Unit 1 or Unit 2 Recirculation Spray (RS) Heat Exchanger Service Water Radiation Monitor Pumps to a RS Service Water discharge pipe which will remain in service. This activity is necessary to support various outage activities/work involving the RS Service Water discharge pipe. Operations Procedures (Safety Evaluation 98-107) 10/16/98 Operations Procedures 1-0P-RC-006 "Isolation and Drain of One Reactor Coolant Loop," and 1-0P-RC-007 "Isolation and Drain of All Reactor Coolant Loops With RHR in Service," were revised to allow exercising the Reactor Coolant System (RCS) loop stop motor operated valves one time prior to isolating a RCS loop for outage maintenance.

Exercising the valves once before closure has proven to reduce seat leakage. The cold leg isolation valve interlocks will be defeated, the valve electrically closed, then reopened.

The same evolution will follow with the hot leg isolation valve.

\ e PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTHNEAR:

October, 1998 Operations Surveillance Procedures (Safety Evaluation 98-108) Surry Monthly Operating Report No. 98-11 Page 14 of 18 10/22/98 Operations Surveillance Procedures 1/2-0SP-TM-003 "Functional Check of Turbine Valves and Limit Switch Operation," are being used as a procedurally controlled temporary modification to test the turbine inlet valves during refueling.

The electric overspeed will be de-energized to open the governor and intercept valves that could be energized due to conditions likely to be present during the period in which the test is performed.

The fuses for this overspeed solenoid will be pulled to clear the condition to allow opening all required turbine valves. Operations Surveillance Procedure (Safety Evaluation 98-112) 10/29/98 Operations Surveillance Procedure 1-0SP-Sl-002 "Charging Pump Head Curve Verification," is being use to control the installation of a temporary flow meter on a Charging pump suction line. The temporary flow meter is needed to gather additional data on the "B" charging pump. The existing flow meter span is too low for the flow conditions required by procedure 1-0SP-Sl-002 which flows the pump on the high end of the pump curve. Operations Surveillance Procedures Periodic Tests Operations Periodic Tests Electrical Periodic Test (Safety Evaluation 93-029, Rev. 2) 10/30/98 The procedurally controlled Temporary Modification used various periodic tests and surveillance procedures to lift leads and install jumpers to allow placing charging pump and feedwater breakers in the test position f9r Engineered Safequards Function (ESF) and undervoltage testing including; the defeat of the transfer bus backup trip from emergency bus undervoltage; the defeat of "C" normal charging pump trip from "B" racked out condition; defeat of charging pump low header pressure and start; defeat of charging pump close circuit bypass from a racked out condition; defeat of feed water pump bearing oil and normal suction header pressure permissive; simulation of safety injection for an under voltage safety injection; and defeat of charging pump damper opening. The actions prevent an unwanted bus transfer .trip while testing unit response to an under voltage safety injection signal. Revision 2 was issued to clarify that fuel movement within the Fuel Building is not restricted.
