e e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: ~-F_EB_R_UA_R_Y~19_9_0~

DC-89-15 REPLACEMENT OF RADIATION MONITOR RM-SW-107 This design change installed an in-line detector in a well to detect radioactivity in the service water discharge from component cooling water heat exchanger 1 D1

  • This change was initiated due to maintenance problems with the existing off-line monitor, caused by river water fouling and the inability of the sample pump to draw a representative sample for monitoring.

SUMMARY

OF SAFETY ANALYSIS This modification is being done to improve the reliability of the monitor which is currently out of service. Seismic analysis of the detector well has been performed. Emergency bus requirements have been maintained. An unreviewed safety question does not exist since the new detector is an enhancement to the existing system.

Sl-89-2292 STATION DEVIATION 02/06/90 (Safety Evaluation #90-0024)

This deviation report is to document that the possibility exists that a 900# gasket was installed in the inlet of 1-RC-SS-1558 &C in lieu of the required 1500# gasket.

Gaskets are rated by the manufacturer to match the pipe/flange ratings as a guide. ASME specifically excludes gaskets as pressure boundary components. Therefore, no stress analysis is applicable to the gasket itself. The physical difference between the 900# and 1500# gaskets is that approximately 2 more coils are in the 1500# gasket. The gaskets have been seated and are pressurized. No increased leakage has been detected during the PT-10 daily testing. The gasket design precludes a catastrophic failure. During containment entries at normal operating pressure, no leakage from the gaskets was observed and any change would be identified via PT-10 or containment radiation monitors.

Therefore, an unreviewed safety question does not exist.

..... e FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: FEBRUARY 1990 TM-S2-90-001 TEMPORARY MODIFICATION 02/08/90 (Safety Evaluation #90-0027)

This temporary modification is to install electrical jumpers in train 1 8 1 safeguards rack from relay Fl-YB to F3-YB to maintain continuity thru circuit while replacing relay F2-YB.

The failure of the jumper would result in the loss of continuity to 1 8 1 train safety injection (SI) actuation relays. Since the 1

A1 train is unaffected and the jumper will be installed only for the time that relay F2-YB is being replaced, and 1 8 1 train SI relays will be unaffected unless jumper fails, an unreviewed safety question is not created. Redundant protection is provided by the train 1 A1 actuations. Backup protection is provided by manual actions to provide the necessary actuations. These actions are directed by the applicable ERG procedures (2-E-0, 2-ES-0, 1/2-FR-H-3). During placement of the jumper, adequate precautions must be taken to prevent inadvertent actuation of the feedwater isolation logic and/or a turbine/reactor trip.

Therefore, an unreviewed safety question is not created.

2-EWR-89-499 ENGINEERING WORK REQUEST 02/13/90 This Engineering Work Request is to evaluate components of the backup air supply system to 2-RC-PCV-2455C for damage due to the failure of the air regulator and subsequent pressure transient in the backup air supply system.

Redundancy provided by an additional power operated relief valve and three code safety valves ensured that no unreviewed safety question exists, and the provisions of the Technical Specifications were not violated.

SCAFFOLD REQUEST UNIT #1 02/13/90 (Safety Evaluation #90-0030)

This request is for the erection of a temporary scaffold to support the replacement of the reel and cable on the fuel handling crane 1-FH-BRDG-13 located in the fuel building (EL 45 1 10 11 ) , W0#076345.

The temporary scaffold is required for safe working.

Installation of scaffold constructed per SUADM-ADM-07 has a high confidence level against failure and was reviewed for effects on accident analyses and equipment operability/function. It is thus concluded that assumptions, bases and probabilities of accident analyses and equipment malfunctions are not affected.

FACILITY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR: FEBRUARY 1990 AC-Sl-90-0221 ADMINISTRATIVE CONTROL 02/22/90 (Safety Evaluation #90-0050)

This change is to place valve l-SW-263 (Appendix R) under administrative control while it is in the manual override position due to ongoing mechanical work in the Mechanical Equipment Room (MER) #3 and the 1/2-SW-P-lOA pump room to prevent spurious valve closure due to smoke created by welding and grinding operations.

The valve can be closed by operators within two minutes of notification by firewatches. Firewatches are located in MER #3 and, if the smoke detectors are inoperable, in the Service Water (SW) pump room. If the SW pump room smoke detectors are operable, operators will be alerted by the Main Control Room annunciator. Since adequate protection is still provided to meet the safe shutdown requirements of 10CFR50, Appendix R, an unreviewed safety question is not created.

AC-Sl-90-02218 ADMINISTRATIVE CONTROL 02/22/90 (Safety Evaluation #90-0052)

This change is to place administrative control over 2-SA-60 and 2-SA-62, service air supply isolation valves to #1 containment, to ensure that containment integrity can be maintained.

Administrative Control over l-SA-60/62 in accordance with SUADM-0-26 ensures that the ability to maintain containment integrity as defined in technical specifications (TS). The valves will be closed immediately upon notification by the Main Control Room (MCR). In addition, control over the valves will ensure the ability to maintain the containment partial pressure within the limits established by TS-3.8. Therefore, an unreviewed safety question is not created.

e e PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/VEAR: FEBRUARY 1990 l/2-TOP-3034 TEMPORARY OPERATING PROCEDURE 02/05/90 WO# 060544 WORK ORDER 02/05/90 WO# 060599 WORK ORDER 02/05/90 WO# 080158 WORK ORDER 02/05/90 (Safety Evaluation #90-0023)

This temporary operating procedure and work orders were to isolate the non-safety related fans, 1-VS-F-88, 9A and 98, from the vent vent system.

Fans and dampers, 1-VS-88 and 9A, need to be repaired to perform their design function. 1-VS-F-58A and B will remain available to run during blanking process. Either 1-VS-F-58A or B will run during the outage of 1-VS-F-9A and B. The work will be performed on non-safety related equipment and will not affect operability of the safety related fans. Therefore, an unreviewed safety question is not created.

l/2-COP-19.0 CHEMISTRY OPERATING PROCEDURE 02/08/90 (Safety Evaluation #90-0025)

A change was made to the procedure to assign administrative control when the underground fuel oil tank access plug is removed during tank sampling operations.

Since the redundant tank will be unaffected and administrative control will exist requiring the plug to be replaced upon issuance of a tornado or hurricane watch/warning, an unreviewed safety question is not created.

l-TOP-4021 TEMPORARY OPERATING PROCEDURE 02/08/90 (Safety Evaluation #90-0026)

This temporary operating procedure was written to identify a possible tube leak in component cooling water (CCW) heat exchanger (HX) 1-CC-E-lA. Helium will be injected into the shell side of the HX to pressurize it, and a helium leak detector will be used on the service water side (tube side) of the HX to identify possible leaking tubes. The HX will be drained and removed from service during the test. The other three CCW HXs will remain operable as required by Technical Specifications.

An unreviewed safety question does not exist because the leak check testing will be performed on an isolated HX which has been removed from service. In addition, the pressure of the helium injected into the HX will be less than the normal operating pressure of the CCW.

This procedure action request (PAR) is to document that the requirements of operating procedure OP-18.3 have been incorporated along with a North Anna escape lock a-ring inspection test into mechanical maintenance procedure MMP-C-G-96.

This procedure provides for inspection of the a-rings on the escape lock of the containment equipment hatch.

This procedure change ensures that containment integrity is met during the entrance into the escape lock of the hatch.

Procedural controls are such that at least one operable escape lock door will be closed during the evolution. Therefore, the health and safety of the public are not affected, and an unreviewed safety question is not created.

The change in the procedure provides for administrative control over the removal of missile protection for the canal low level trip circuitry during the performance of technical specification required surveillance testing.

An unreviewed safety question does not exist since the missile shield is installed to protect the circuitry from wind generated missiles and upon removal the shield can be replaced (if severe weather is forecast or threatening) utilizing the administrative controls.

1-PT-18.8 PERIODIC TEST (Safety Evaluation #90-0066) 02/27/90 2-PT-18.8 (Safety Evaluation #90-0058) 1-PT-18.8A (Safety Evaluation #90-0065) 2-PT-18.BA (Safety Evaluation #90-0067)

This procedure change documented that the differential pressure method.of testing the check valves for the charging pump service water and charging pump component cooling water subsystems is unnecessary and is being removed from the periodic test.

An unreviewed safety question does not exist since the check valves will still be tested in the closed position to ensure system operability. This change is in accordance with the ASME XI plan and will not affect the ability of the subject subsystems to mitigate the consequences of an accident.
