SUMMARY
OF CIIANGES, TESTS, AND EXPERIMENTS FOR TIIE I1 OPE CREEK GENERATING STATION MONTH JANUARY 1996 The following items have been evaluated to determine:
- 1. If the probability of occurrence or the consequences of an accident or malfunction of equipment important to safety previously evaluated in the safety analysis report may be increased; or
- 2. If a possibility for an accident or malfunction of a different type than any evaluated previously in the safety analysis report may be created; or
- 3. If the margin of safety as defined in the basis for any technical specification is reduced.
The 10CFR50.59 Safety Evaluations showed that these items did not create a new safety hazard to the plant nor did they affect the safe shutdown of the reactor. These items did not change the plant effluent releases and did not alter the existing emitonmental impact. The 10CFR50.59 Safety Evaluations determined that no unreviewed safety or environmental questions are involved.
l Test Summary of Safety Evaluation e 4EX-3510: PACKAGE 1. INSTALLATION OF EXPERIMENTAL FILLS IN COOLING TOWER This test installed several new modular plastic fills and structural supports in the Hope Creek Cooling Tower. Fills were placed where there was suflicient space for installation without removing existing structural supports or asbestos cement board fill sheets. The new modular plastic fills were installed to evaluate their performance and susceptibility to biological fouling during power operation. The cooling capability of the Hope Creek Circulating Water system will not be affected because of the ,
small amour.t cf fill mstalled. The cooling tower is described only in a general sense in the '
Hope Creek UFSAR. This test does not change that description or the Design Parameters listed in UFSAR Table 10.4-4, therefore there is no change to the plant as described in the UFSAR. However, a test to accumulate data concerning bio-fouling is not described in j the UFSAR. There are no previously anticipated operational transients or design basis accidents affected by this proposal. The Circulating Water System is not considered in the Accident Analysis because it is not required to be operational during the events described in Chapter 15 of the UFSAR.
Therefore, this test does not increase the probability or consequences of an accident I previously described in the UFSAR and does not involve an Unreviewed Safety Question. !
Design Changes Summary of Safety Evaluations e 4EC-3411: PACKAGE 3. RHR LOOP 'D' TO LOOP 'B' CROSS-TIE This design change will allow RHR pump 'D"to be aligned to utilize the heat removal capacity of Heat Exchanger 'B." This is a change to the facility as described in the UFSAR Sections 5.4.7.1,5.4.7.2.1, and 7.3.1.1.4 and Figures 5.4-13 and 6.3-12. This package changes the position of valve 1BCV-571 from normally open (as stated in package 2 of this Design Change) to normally closed and maintains valve 1BCV-570 as normally closed during power operation, when the cross-tie is not inservice. This change does not affect the 4
performance or capability of the RHR System or any other system required to automatically actuate and mitigate the consequences of antici3ated operational transients or aostulated design basis accidents previously evaluated in t7e UFSAR. This change adc s interconnecting piping and two manual isolation valves between RHk pumps' B and ;
D discharge headers. Both valves will be normally closed. Installation of the proposed modification will not affect the failure mode or failure probability of any equipment important to safety.
Therefore, this design change does not increase the probability or consequences of an accident previously described in the UFSAR and does not involve an Unreviewed Safety Question.
e 4EC-3463: PACKAGES 1,2 & 3. EXTRACTION STEC.1 REPLACEMENT This design change replaces 71 ain carbon steel pipe in portions of the low pressure feedwater heater extraction steam mes with carbon steel pipe that has a metallurgically bonded alloy cladding. This is being done as part of the Hope Creek iron reduction program. The new
- material was selected because ofits high corrosion and erosion resistance. The piping insulation will be changed from calcium silicate to blanket type Fiberglas. This is bemg done to increase reusability and ease reinstallation. The piping is designed to the same )
criteria as the original installation and, therefore. there is no afTect on failure modes, l operational transients, design basis accidents and equipment malfunctions. The extraction l steam system is not a high energy fluid system. The change does not affect the pipe break I accident scenarios described ? . UFSAR Sections 3.6 and 15.6.5.
Therefore, this de.6ge chan; . does not increase the probability or consequences of an
. accident previously described in the UFSAR and does not involve an Unreviewed Safety )
Question.
. 4EC-3485: PACKAGE 1 ADDITION OF REACTOR VESSEL CAVITY FLOOD-UP TRANSMITTER This design change adds a new transmitter and relocates an indicator on the "A" Channel instrument rack shown on UFSAR Figure 5.4-4. Both devices are located downstream of excess flow check valves, therefore, there is no impact on the Reactor coolant and Primary Containment pressure boundaries. The new transmitter will be used when the reactor vessel head is removed and the cavity is flooded.
This transmitter provides a means for Control Room Operators to trend the reactor cavity water level when the N027 transmitter is made inoperable by removal of the reactor head.
The new indicator is electrically, environmentally, and seismically equivalent to the N027 transmitter. This Design Change does not affect the seismic qualification, fire protection, electrical separation er interaction studies of the instrument rack. The addition of a qualified transmitter to a qualified instrument rack does not affect the probability or consequences of an accident, or malfunction of equipment important to safety. Nor does it introduce any new accidents or malfunctions Therefore, this design change does not increase the probability or consequences of an accident previously described in the UFSAR and does not involve an Unreviewed Safety Question.

Design Channes Summary of Safety Evaluations (continued) e 4EC-3517: PACKAGE 1. REPLACEMENT OF HPCI/RCIC DRAIN LINE This design change replaced the carbon steel line and fittings from the ' Tee" joining the Main Steam and HPCI/RCIC drains to the condenser with a corrosion / erosion resistant material.
No parameters are affected by this change. The piping is designed to the same criteria as the original installation and, therefore, there is no affect on failure modes, operational transients, design basis accidents and equipment malfunctions.
Therefore, this design change does not increase the probability or consequences of an accident previously described in the UFSAR and does not involve an Unreviewed Safety Question.
e 4EC-3579 DRILL A WEEP HOLE IN SELECTED FLEXIBLE WEDGE AND DOUBLE DISC GATE VALVES This design change drills weep holes in the reactor side of valve discs to provide a relief path for the bonnet to prevent pressure locking.
Industry documents describe events where flexible wedge or double disc gate valves have failed to open due to pressure locking. This occurs when a closed flexible wedge or double disc gate valve has high ? ressure fluid trapped in the valve bonnet cavity followed ,
by system depressurization or wn,. :he bonnet is pressurized due to thermal expansion of l the entrapped fluid. Under these conditions the opening capability of the motor operator may not be sufficient to overcome the force on the valve disc. This change modifies valves at Hope Creek with active safety functions identified as susceptible to pressure locking. Packages will be prepared to implement the modification on the each susceptible valve or group of valves and will be reported when complete.
The weep holes enhance valve operability since they preclude pressure locking. The vendor has confirmed the structural adequacy of the valves is not affected by drilling a weep hole. Valve function is unchanged and remains as described in the UFSAR and the Technical Specifications. No new failure modes from those considered in the UFSAR are Aded. Abihty of the valves to open under accident conditions is enhanced. The weep holes will not prevent the valves from performing their primary containment isolation function. Post-modification testing willinclude Appendix J, Type C Leak Rate testing. ,

Design Changes Summary of Safety Evaluations (continued) e 4H E-0300. REWORK CLOSED MOTOR OPERATED VALVE (MOV)
POSITION INDICATIONS ON VARIOUS MOVs This design change modifies the motor operators for various valves. A separate package will be prepared for each valve and reported when it is implemented.
In summary, limit switch LS-7 will be reset to provide unambiguous indication of MOV position by maintaining illumination of the valve open light until the valve has reached the full closed position. To allow the resetting of LS-7, limit switch LS-5, which is presently used to bypass torque switch WS-18 on imtial opening, will be jumpered to bypass WS-18 during normal operations. This is necessaiy because 1,S-5 and LS-7 are integral to the same rotor, R2. Since torque switch WS-18 will be bypassed, this change, also, eliminates the potential for the torque switch to prevent valve opening in response to remote-manual initiation. The jumper will be removed during testing and limit switch calibration to minimize the potential for mechanical damage to the valve, which is possible when conducting limit testing.
Discussion of torque switches in the UFSAR, Section 6.3.4.1, is part of a general discussion of testing performed on ECCS components, and does not establish criteria for determining when torque switches are required. However, most of these torque switches are shown on figures in the UFSAR and therefore, consequently these are changes that involve a change to the facility as described in the UFSAR.
The revision of the LS-7 setting and the deletion of the open torque feature do not adversely affect the design basis or operation cf the afTected MOV, impact its ability to 3erform required functions, or modify the MOV in such a manner as to cause the valve to se susceptible to failure modes different from those considered in the UFSAR.

. 411E-0258: PACKAGE 02 SW STRAINER SMALL BORE VENT AND DRAIN LI2'FsPIPING REPLACEM ENT This design change replaces the one and two inch SW strainer small bore vent and drain cement lined piping with 6% molybdenum austenitic stainless steel piping which meets the original design requirements and is of the same schedule as the original piping. This design change upgrades the existing small bore !
piping as part of PSE&G's Service Water piping upgrade effort. Galvanic corrosion of I dissimilar metals will be prevented through the use of Maloney insulating kits with l Garlock gaskets. Therefore, it does not introduce any new credible failure scenarios, or adversely impact the existing failure modes. The system P& ids in the UFSAR will have to be revised to reflect the new material. (NOTE - Completion of 4HE-0258, Package 01 was reported last month)
Therefore, this design change does not increase the probability or consequences of an accident previously described in the UFSAR and does not involve an Unreviewed Safety Question.

UFSAR Change Notices Summary of Safety Evaluations e UFSAR CIIANGE NOTICE CN 95-49. TEMPERATURE AND HUMIDITY EXCURSIONS IN THE MAIN CONTROL ROOM (#5510) AND ASSOCIATED AREAS This change notice revises UFSAR Section 9.4.1.1.1, Control Room Supply System; D7.5, Environmental Design Criteria; D5.1, Design Criteria for Control Room; and D3.5, Control Area HVAC Specification to reflect a temperature range of 72 F i 6 F and a Relative Humidity range of 20% to 60% for the nominal expected environmental conditions in the control room area. These values accurately reflect the requirements for normal plant operation and will not introduce any new effects to the plant or system operation. These values are compatible with existing plant and equipment design. The currently listed environmental conditions for the Control Room were extracted from PNO-A61-4270-0015, the General Electric specification. GE has identified these values as the expected conditions as a result of calculations. They do not represent the limiting conditions for operation. The Control Room Emergency Filtration (CREF) charcoal absorbers are the most limiting components with respect to relative humidity requirements in the Control Room Area. The relative humidity requirement for the charcoal absorbers will be met a control room relative humidity of 60%. The operating parameters of the Control Room Supply (CRS) System or any other control room associated equipment will not be changed. This change mcorporates limits consistent with the original design. It does not alter or degrade the present operating modes of the system.
Therefore, this UFSAR change does not increase the probability or consequences of an accident previously described in the UFSAR and does not involve an Unreviewed Safety l
Question.
- UFSAR CIIANGE NOTICE CN 96-07. HOPE CREEK UFSAR SECTION 9.3.37.1 REVISION This change notice revises UFSAR Section 9.3.3.7.1, Instrumentation Application, to reflect the installed instrumentation. The text is being changed from 1ocal radiation ?rocessor" and ' processor" to ' programmable controller." The UFSAR currently cescribes the sump pumps as being controlled by a local radiation processor (LRP). However, the start and stop control functions described in UFSAR Section 9.3.3.7.1 are actually controlled by a programmable controller. There are no affects on the operational transients or postulated design basis accidents previously evaluated in the UFSAR because neither the Drywell Floor Drain nor Drywell Equipment Sump Pumps are credited in the Hope Creek UFSAR as mitigating the consequences of an accident. The plant drainage systems have no safety-related function. The failure of a programmable controller would have the same result as the failure of an LRP. This change does not affect the control scheme described in the UFSAR.
Therefore, this UFSAR change does not increase the probability or consequences of an .
accident previously described in the UFSAR and does not involve an Unreviewed Safety l Question.

UFSAR Change Notices Summary of Safety Evaluations (continued) e UFSAR CIIANGE NOTICE CN 96-08. EDG OPERATION - MANUAL MAKEUP TO TIIE DG LUBE OIL MAKEUP TANK This change will allow making up to the Emergency Diesel Generator (EDG) Lube Oil (LO) Makeup Tanks locally via the mstalled conservation vent fitting at the top of the tank. UFSAR Section 9.5.7 is being revised to allow filling of the Lube Oil Makeup Tank from other than the installed LO fill piping.
This procedure change will not introduce any new failure modes in relatien to the credible accidents / malfunctions described in the UFSAR. This proposal does not alter the operational or postulated design basis previously evaluated in the UFSAR. This procedure change does not degrade the performance of the EDGs nor does it affect any design specification of the EDGs and associated equipment. No physical changes are made to any system, structure or component.
Therefore, this UFSAR change does not increase the probability or consequences of an accident previously described in the UFSAR and does not involve an Unreviewed Safety Question.
e UFSAR CHANGE NOTICE IICR.80002, HOPE CREEK FUEL POOL COOLING AND CLEANUP SYSTEM UFSAR CHANGE This change will revise UFSAR Section 9.1.3 to add the faulted configuration of only one pump and one heat exchanger in service to the description. The current UFSAR Section 9.1.3 describes only the faulted configuration of one pump and two heat exchangers in service. Both these configurations were reviewed and approved by the NRC in the HCGS SER as part of the design bases for the Fuel Pool Cooling and Cleanup (FPCC) System. This failure results in a fuel pool temperature of 174 F. The change will not affect any plant configuration or procedures as described in the UFSAR. The failure associated with this change is the failure of one loop of the FPCC. This failure has been previously evaluated and accepted by the NRC. This change does not introduce any new failures. There are no transients or accidents previously evaluated in the UFSAR applicable to the FPCC. Malfunctions to the FPCC System which would cause a loss of one loop of FPCC are listed in UFSAR Table 9.1-3.
This change will, also, change the reference for the location of the decay heat information from Table 9.1-18 to Table 9.1-17 in the last paragraph of UFSAR Section 9.1.3.3. This second change is a typographical correction Therefore, this UFSAR change does not increase the probability or consequences of an accident previously described i:. the UFSAR and does not involve an Unreviewed Safety Question.

Temporary Modifications Summary of Safety Evaluations e TM# 95-060, SSWS LOOP "A" & LOOP "B" TEMPORARY DISCIIARGE PIPING TO Mil 50 & MII51 This Temporary Modification diverts Service Water l normally flowing to the Cooling Tower Basin or the Tower Bypass Line to manholes in the yard during operational conditions 4 or 5. This Modification will permit maintenance on yard piping for the service Water System. The SSWS emergency bypass line has been designed to facilitate the passage of the required SSWS flow through each of the SSWS/ !
SACS loops in the event of a failure of the yard discharge piping. Based on an analysis of l the piping geometry in the temporary piping, piping stresses as a result of a dynamic event )
will not exceed allowable stresses. The margms of safety as discussed in the Technical Specifications will not be impacted by the utilization of the temporary piping.
Therefore, this temporary modification does not increase the probability or consequences of an accident previously described in the UFSAR and does not involve an Unreviewed Safety Question.
. TM# 96-001, INSTALLATION OF TEMPORARY SERVICE WATER STRAINER HACKWASit DISCIIARGE LINES This Temporary Modification removes the Service Water strainer eflluent discharge from the normal flow path shown on UFSAR Figure 9.2-2 and diverts the flow back to the river via two of the Unit Il spare bays. This is being done to allow replacement of piping on the traveling screens and strainers in accordance with Design Change 4HE-0207. There are no operational transients or postulated design bases accidents that are applicable to this proposal. The backwash function is not altered by this proposal. The backwash function does not impact any radiological system. There are no malfunctions of equipment important to safety that are considered applicable to this proposal. A complete failure of this temporary modification will not cause an accident or change single failure criteria for any safety-related component or system.
Therefore, this temporary modification does not increase the probability or consequences of an accident previously described in the UFSAR and does not involve an Unreviewed Safety Question.
Deficiency Report Summary of Safety Evaluation e DEFICIENCY REPORT 960115095, DIESEL GENERATOR JACKET WATER COOLING llEADER, I A-G-400 ORIFICE EROSION - ORIFICE SIZE EVALUATION AND TESTING PORTION ONLY This Deficiency Report disposition results in re-installation of orifices in the Diesel Generator "A"(A EDG)
- Jacket Water Cooling system that are at variance with the design documentation for testing and evaluation. This test will verify their acceptability with the design criteria. The orifices represent the sizes found installed in the EDG during maintenance. The parameters affected are the relative cooling water flows to the EDG engine and inlet turbocharger. Failure of the orifices to provide the required flow (orifice too small) could result in inadequate cooling. Failure of the orifice to properly restrict flow (orifice too large) could result in pump failure from runout. The activity will be performed while the a EDG is considered inoperable for maintenance. While the unit is in Operational Condition 4 or 5, only two of four diesels are required to be operable. The functional performance of the Jacket Water Cooling System will not be altered by this re-installation.
Therefore, this deficiency report disposition does not increase the probability or conseguences of an accident previously described in the UFSAR and does not involve an i Unreviewed Safety Question. )

Other Summary of Safety Evaluation e IICR.8-0003, HOPE CREEK RELOAD SAFETY EVALUATION FOR CYCLE 7 This safety evaluation addresses the impact of Hope Creek reload core design on the cycle 6 operation.
There will be a discharge of 232 fuel assembhes at end of cycle 5 operation. The safety analyses for the reload are reviewed.
The limiting transients previously evaluated in Chapter 15 of the UFSAR have been re-analyzed for the Hope Creek cycle 6 / reload 5 design. A new set of core operating limits is generated and documented in the Core Operating Limits Report which is referenced in the Technical Specification. This analysis was performed with methods previously reviewed and approved by the NRC staff for reload design and analysis purposes.
The replaced fuel bundles have the same nuclear design and minor axial zoning change. The minor axial zoning change has economical benefits while maintaining the same nuclear and thermal-hydraulic characteristics. The zoning change takes advantage of the large shutdown margin available for cycle 6 and therefore relax the zoning requirement for shutdown consideration.
Based on the GE projected cycle performance, all aspects of the fuel thermal-mechanical bases have been reviewed. The projected cycle 6 core design and operation will not violate any fuel thermal-mechanical design criteria.
Therefore, this Safety Evaluation does not increase the probability or consequences of an accident previously described in the UFSAR and does not involve an Unreviewed Safety Question.
