e e PAGE 9 FACIUTY CHANGES'THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR SEPTEMBER 1988 SCAFFOLD REQUEST 09/02/88 Erection of temporary scaffolding located in Unit 2 safeguards to work NRV-MS-201A/B/C.

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.

SCAFFOLD REQUEST 09/06/88 Erection of temporary scaffolding located in the Unit 1 Turbine Building Basement to work piping for bowser.

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.

AC S2-88-0906 ADMINISTRATIVE CONTROL 09/06/88 Administrative control will be maintained while the charging pump component cooling pump drain valve is open to feed and to bleed the system to increase chromate concentration; an operator will be stationed at the drain valve to close it immediately should the head tank level drop to~ 30%.

Feeding and bleeding the charging pump component cooling system by opening its pump's drain valve will not affect the operability of the charging system. It will enhance corrosion control by the addition of chromates. Therefore, this change does not constitute an unreviewed safety question.

SCAFFOLD REQUEST 09/08/88 Erection of temporary scaffolding located in Unit 2 Safeguards to work IS! Inspections for NOE.

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.

PAGE 10 e e FACIUTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR SEPTEMBER 1988 TM S2-88-069 TEMPORARY MODIFICATION 09/09/88 This modification removed check valve internals from 2-BD-558 and installed adapter and jumper hose to Condensate Polishing waste neutralization or low conductivity sumps.

The steam generators will be at atmospheric pressure during implementation of this jumper. Therefore, the probability of a steam generator tube rupture is not credible. If leakage on the jumper should occur, the release can be terminated immediately by securing the R & T pump. Therefore, no unreviewed safety question exists.

AC Sl-88-0911 ADMINISTRATIVE CONTROL 09/10/88 Administrative control will be maintained at the emergency switchgear room door while it is temporarily removed by establishing flood watch at the door and turbine building pit areas. The dike will be reinstalled in the event of a flood.

The removal of this dike will not adversely affect any safety related equipment, therefore does not create an. unreviewed safety question.

AC S2-88-0909 ADMINISTRATIVE CONTROL 09/10/88 Valve 2-CC-104, manual isolation valve downstream of TV-CC-209A will be used while under administrative control in accordance with SUADM-0-026 to ensure containment integrity.

Administrative control of 2-CC-l 04 does not constitute an unreviewed safety question, since it will ensure that containment integrity is maintained. *

  • SCAFFOLD REQUEST 09/12/88 Erection of temporary scaffolding located in Unit 2

Installation of this temporary scaffolding was reviewed for effect on accident analyses and equipment operability/function.

.' e e FACIIJTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR SEPTEMBER 1988 SCAFFOLD REQUEST 09/12/88 Erection of temporary scaffolding located in Unit 2 containment to work IS! inspection in the vicinity of RHR piping.

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 maifunctions are not affected. Scaffolding to be removed prior to reactor coolant system exceeding 200°F.

SCAFFOLD REQUEST 09/12/88 Erection of temporary scaffolding located in the Unit 2 containment RHR flats to work IS! inspections in the vicinity of both RHR pumps and associated piping.

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. Scaffolding will be removed prior to reactor coolant system >200°F.

AC-Sl-88-0912 ADMINISTRATIVE CONTROL 09/12/88 Administrative control is required to close the door between the emergency switchgear room and the turbine building when necessary.

The door is blocked open to allow access for an exhaust duct for maintenance work.

The design basis accident was reviewed and it was determined that the emergency switchgear door will be closed by the dedicated continuous fire watch when the control room is required to be pressurized.

Therefore, no unreviewed safety question exist.

TM-S2-88-075 TEMPORARY MODIFICATION 09/12/88 This change installed pressure gauges on 2-RH-38/39 and the suction lines for 2-RH-P-lA/lB while performing 2-PT-30.1.

Since the probability of the temporary fittings and/or gauges chance of failing is minimum, the bases, assumptions and probabilities of accident analyses and equipment malfunctions are not affected.

e e PAGE 13 FACIIJTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR EWR-88-039 ENGINEERING WORK REQUEST 09/12/88 This request was to document that the auxiliary feedwater control switch lights (green, amber, red) would extinguish with the switch in "pull-to-lock" position. A white light (added above the red light) would illuminate when the pump breaker was in the "connected" position and the breaker closing control power was available.*

The added white light enhances operator's awareness of the breaker status. Changing to lights extinguishing on "pull-to-lock" complies with human factors concerns. There is no other effect on plant operation. Therefore, no unreviewed safety question exists **

EWR-88-296 ENGINEERING WORK REQUEST 09/12/88 This request was to evaluate operation with the emergency diesel generators (EDG) main air intake louvers failed open.

This change does not affect the operation of the EDGs because the louvers are open while they are in operation. Leaving the louvers open will help to enhance air displacement (in the event of a fire) if the carbon dioxide system is actuated. Therefore, an unreviewed safety question does not exist.

TM-Sl-88-136 TEMPORARY MODIFICATION 09/14/88 This change removed the check valve internals from 1-BD-558 and installed adaptor and jumper hose to condensate polishing waste neutralization or low conductivity sumps.

The steam generators will be at atmospheric pressure during implementation. The probability of a steam generator tube rupture is not credible. If leakage on the jumper should occur the release can be terminated immediately by securing the RT pump. Therefore no unreviewed safety question exists.

TM-S2-88-082 TEMPORARY MODIFICATION 09/19/88 This change installed a flexible hose from 2-DG-74 to 2-CH-443. In addition, valves MOV-2381, 2-DG-TV-208B, HCV-2522A/B/C and HCV-2523 were closed.

Installation of a hose allowing the primary drains tank to be pumped to the volume control tank was reviewed for effect on accident analyses and equipment operability/function. Conclusion is that assumption_s, bases and probabiliti~s of accident analyses* and equipment malfunctions are not affected.

PAGE 14

  • . e e FACIIJTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR SEPTEMBER 1988 TM-Sl-88-141 TEMPORARY MODIFICATION 09/19/88 This change installed pressure gauges on l-RH-38/39 and the suction lines for 1-RH-P-lA/lB while performing l-PT-30.1 Since the probability of the temporary fittings and/or gauges chance of failing is minimum, the bases, assumptions and probabilities of accident analyses and .equipment malfunctions are not affected.

TM-S2-88-084 TEMPORARY MODIFICATION 09/22/88 This change blocked open the pressurizer power operated relief valves (PORVs) prior to initiation of maintenance to ensure that overpressure protection is available.

Technical specification 3.1.G requires a relief path equivalent to one open PORV. This change ensures two relief paths, one through each PORV and therefore, provides adequate overpressure protection. No unreviewed safety question is created.

TM-S2-88-087 TEMPORARY MODIFICATION 09/24/88 This change removed the PORVs for the pressurizer and a piece of one-eighth inch garlock gasket material will be placed over the PORVs flanges using four of the eight bolts to hand tighten. The gasket of material will not hold pressure but will keep dirt out of the pressurizer PORV lines.

With the PORVs removed at cold shutdown, a pressure relief path is assured. The material placed over the valve flange will not interfere With the relief flow thru the lines. Therefore, no unreviewed safety question is created.

TM-S2-88-088 TEMPORARY MODIFICATION 09/24/88 The safety valves *for the pressurizer will be removed and a piece of one-eighth inch garlock gasket material will be placed over the three safety valve flanges using four of the eight bolts hand tightened. The gasket material will not hold pressure but will keep dirt out of the safety valve lines.

With the safety valves removed at cold shutdown, a pressure relief path is assured. The material placed over the valve flange will not interfere with the relief flow thru the lines. Therefore, no unreviewed safety question is created.

PAGE 15 e e FACIIJTY CHANGES THAT DID NOT REQUIRE NRC APPROVAL MONTH/YEAR SEPTEMBER 1988 TM-S2-88-089 TEMPORARY MODIFICATION 09/25/88 This change was to defeat the automatic reactor trips by jumpering out relays affecting the closed reactor trip breakers. While the change is in effect all power to control and shutdown rods will be physically disconnected and the rods will be fully inserted.

While this temporary modification is in effect the reactor will remain at cold shutdown with all rods inserted and all sources of power to the rod drive mechanisms removed. Reactor trip breakers shall be opened each night upon completion of the work. No method exists for uncontrolled rod withdrawal with all power removed from rod drive mechanisms. Therefore, there is no possibility of this accident and an unreviewed safety question is not created.

PAGE 16 e e PROCEDURE OR METHOD OF OPERATION CHANGES THAT DID NOT REQUIRE NRG APPROVAL MONTH/YEAR SEPTEMBER 1988 FS-88-055 FINAL SAFETY ANALYSIS REPORT 09/06/88 This revision to section 9.9 is a general revision to clarify and update the data within the UFSAR with present operational and design information.

This review determined that no unreviewed safety question exists since this revision has not altered the basic function of the affected systems.

. EWR-88-319 ENGINEERING WORK REQUEST 09/12/88 This request justified the operation of Surry Unit 2 with RV-2209 in an untested condition per ASME XI.

No unreviewed safety question exists as calculations have been performed which show even if the relief valve does not lift and piping pressurization occurs. No unsafe malfunction of equipment will occur.
