INTRODUCTION

Salem Generating Station No. 1 Unit *is a four loop pressurized water reactor of.. 109 0 MWe Net Capacity, owned by Public Service Electric and Gas.Company,. Philadelphia Electric Company, Atlantic Electric Company,

and DelMarva Power and Light Company;. located in Lower Alloway Creek Township, Salem County, New Jersey. The nuclear steam supply system was supplied by Westinghouse. The architect/engineer was Public Ser-vice Electric and Gas Company, and the constructor was United Engineers

and Constructors., Inc. of .Philadelphia, Pennsylvania. The condenser cooling method is a once thru cooling system, and the Delaware River is the condenser cooling water source. The plant is subject to license DPR-70 ,. issued August 13, 1976 pursuant to Docket Number 50-272. The e date of initial reactor criticality was December 11, 1976, and genera-tion of power began December 25, 1976 .

HIGHLIGHTS

Operating License No. DPR-70 was issued for Salem No. l Unit on August 13, 1976. This was a limited operating license permitting 1% of rated thermal power (33.38 MWt) and provided for a sequential approach to power, taking into consideration various incomplete con-struction items, preoperational tests and startup tests.

The initial loading of the core was started on Atigust 17, 1976, and

required 55 hours6.365741e-4 days 0.0153 hours 9.093915e-5 weeks 2.09275e-5 months to complete.

On December 1, 1976, the operating license was amended to authorize operation of the reactor at 100% of rated core thermal power (3,338

MWt) with a sequential approach and NRC authorization required prior to proceeding to 20, 40, and 90% power stages.

Hot shutdown testing was completed on December 8, 1976 with initial

criticality being attained on December 11, 1976 and hot standby and zero physics power testing being completed on December 17, 1976.

- Authorization to proceed to Model (Power Operation), not to exceed 20% of rated core power (667.6 MWt), was received on December 17, 1976 *

The unit was synchronized to the electric system for the first time powered by nuclear heat on December 25. The 10% power level test program was in progress at the end of the report period.

SUMMARY

OF OPERATING EXPERIENCE The following is a chronological description of Plant Operations includ-ing other pertinent items of interest for the period August 13, 1976 to*

December 31, 1976. *

8-13 Operating license DPR-70 for No *. 1 Unit was issued by the Nuclear Regulatory Commission.

- 8-17 Initia*l Core Loading was. started. The first fuel assembly was placed. in position C-4* at 2226 hours0.0258 days 0.618 hours 0.00368 weeks 8.46993e-4 months .

9.,..21 Last fuel. assembly placed in core to complete the Initial Core Loading at 0456 hours0.00528 days 0.127 hours 7.539683e-4 weeks 1.73508e-4 months . The total core loading time was approxi-mately 79 hours9.143519e-4 days 0.0219 hours 1.306217e-4 weeks 3.00595e-5 months . o.f. this total, 24 hours2.777778e-4 days 0.00667 hours 3.968254e-5 weeks 9.132e-6 months were required for

repair. of two air-,motor failures on the transfer carriage, manipulator crane position selsyn failure, electrical noise interference with portable detectors and other minor difficulties.

Actual fuel movement. time was approximately 55 hours6.365741e-4 days 0.0153 hours 9.093915e-5 weeks 2.09275e-5 months .

9-23 Received authori-zation from the Nuclear Regulatory Commission to

proceed to Operational Mode 4 (Hot Shutdown) pursuant to Attach-ment l to License DPR-70. This permission was granted based on satisfactory completion of reactor coolant sys*tem primary sensors response. time testing.

11-25 Received authorization from the Nuclear Regulatory Comm:Lssion to

*.proceed. to Operational Mode 3 (Hot Standby) pursuant to Attach-ment 1 to License.DPR...,70 .. This permission was granted based on satisfactory completion of the following:

1) Testing operation of Residual He.;it Removal Pumps recirculation valves 11RH29 and 12RH29.

2) Testing motor winding temperatures of Residual Heat Removal Pump Motors Nos. 11 and 12.

3) Testing four specified snubbers on the Residual Heat Removal System.

'** 4) 5)

Testing of the Boron Recycle System.

Testing process radiation monitors, excluding those required for fuel loading.

6) Demonstration of beta dosimetry capability.

7) Testing Service Water System .

8) Testing chilled: water portion o.f the Control Room Air Con-ditioning System.

9) Preparation of three specified radiochemistry procedures.

10) Replacement of existing standby charcoal filters in the Auxiliary Building Ventilation System with charcoal filters*

capable of removing 90 percent of.the organic iodines .

11-30 At 2239 hours0.0259 days 0.622 hours 0.0037 weeks 8.519395e-4 months , R_eactor Trip/Safety Injection was initiated due

... __ - to high steam line* flow in coincidence with low Tavg. Plant was

. in Hot Standby, 540°F Tavg and 2235 psig reactor coolant pressure.

Technicians were working. on No. 12 Steam Generator (SG) steam flow

-Channel 1 which was tripped. With reactor coolant temperature less than 543.°F, all four channels of low Tavg were tripped. A pre-mature - lifting of- a -No.. 14 safety valve resulted in a high steam flow. signal.". With No. 12 SG steam flow tripped and a high steam flow signal on No... 14 SG ,. the required two of four signals were available.. This: in coincidence with an actual low Tavg caused the

- - Reactor Trip/Safety Injection.

At 2301 hours0.0266 days 0.639 hours 0.0038 weeks 8.755305e-4 months , while recovering from the first inadvertent .safety injection actuation'" a second SI.actuation occurred. The condi-tions. prior to, cause, and duration of the second ECCS actuation were identical to the first event .

12-1 At 0238,- a Reactor Trip/Safety Injection was initiated due to high steam-line differential pressure P4. Prior to the event, the unit was in Hot Standby,. at 547°F and 22'35 psig* reactor coolant* pressure.

Based on a review of recorder traces,. a No. 14 SG safety valve again lifted prematurely causing the steam line differential pres-

sure P4 safety injection.

12:-3. At 0315, a safety injection _occurred. Prior to the event, the unit was in Hot Standby with 537°F Tavg and 2235 psig reactor coolant pressure. No indication of the cause of this event appeared on. the status- panel. The computer did not print out a sequence of

events but did print out "12 Steam Generator b.P Pressure Reactor Trip SI". Prior to the SI actuation, Technicians were working on No. 12 SG steam flow Channel II. They had hooked up a brush re-corder to the Channel II transmitter output, channel output, and steam pressure channel. When hooking up to No. 12 SG steam pres-

-* sure channel III, the SI took place. After the SI, it was discovered that the Technician mistakenly used grounded test leads

when.hooking up the brush.recorder to the various steam flow and steam pressure channels.

A special test was conducted in order to demonstrate and verify that the inadvertent Safety Injection that occurred was in fact caused.by a Technician mistakenly using grounded test leads when hooking up a brush recorder.

These test results coincide with the events that took place during the Safety Injection that occurred. Based on these results, the

inadvertent Safety .. Injection was caused by a Technician mistakenly using grounded. leads.

12-5 Received. authorization from the Nuclear Regulatory Commission to proceed to Operational Mode .. 2 (Startup) pursuant to Attachment 1 to License . DPR-70. This permission was granted based on satis-

factory completion of .the following:

PLANT OR PROCEDURE CHANGES, TESTS, EXPERIMENTS, AND SAFETY-RELATED MAINTENANCE Amendments to Facility License or Technical Specification Facility or Procedure Changes Requiring NRC Approval

Tests and Experiments Requiring NRC Approval Other Changes, Tests.and Experiments Corrective Maintenance. of Safety-Related Equipment

Amendments to Facility License or.Technical Specifications On September 10, 1976, the Nuclear Regulatory Commission issued Amendment No. 1 to the Facility Operating License for Salem Nuclear

Generating Station,. Uni.t No. 1 - DPR-70.

The amendment revises portions of Attachment 1 to License No. DPR-70 and consists* of (1) changing the sequence for conducting certain pre-operational tests . and. startup tests, and (2) deleting the requirement for testing the feedwater snubbers and (3) deleting the requirement for

completing certain maintenance _procedures for the limited operation for testing permitted by License DPR-70.

On September 29, 1976, the Nuclear Regulatory Commission issued Amendment No. 2 to the Facility Operating License for Sale:m Nuclear

Generating Station, Unit No. 1 - DPR-70. The amendment reads as follows:

"Amendment No. 2 to Facility Operating License No. DPR-70 has been issued to correct typographical errors and inadvertent omissions. The staff has concluded. that the changes are editorial corrections which

- resolve conflicting requirements involving the containment atmosphere radiation monitoring system. We have, therefore,. concluded that the changes (1) do not. increase the probability or consequences* of accidents

previously considered; (2) do not involve a decrease in safety margin nor do they involve new hazards considerations; and (3) that there is reason-able assuran.ce that the changes will not endanger the health and safety

of the public."

On December 1, 1976, the Nuclear Regulatory Commission issued Amendment- No. 3 to the Facility Operating License for Salem Nuclear

Generating Station, Unit No. 1 - DPR-70. The amendment reads as follows: * * *

"The Nuclear Regulatory Commission has issued the enclosed Amendment No. 3 to Facility Operating License No. DPR-70. Amendment No. 3 is effective .. as of the date of issuance~ Facility Operating License No. DPR-.70, as amended,. shall exp.ire at midnight~ September 25, 2008.

In accordance with the Commission's Supplemental Statement of General Policy of November .5, . 1976, (41 F.R*. 49898, November 11, 1976) ,. the staff has . determined. in the enclosed Environmental Assessment, that use of revised .values for reprocessing and waste management would not tilt the cost':"'"benefit balance for Salem Unit No. 1 against issuance of a full power operating license.. Accordingly, Amendment No. , 3 to License

No. DPR':"'"70 authorizes the Public Service Eiectric and Gas Company to operate the Salem Nuclear Generating Station, Unit No. 1 at a reactor core power level of 3338 megawatts thermal (one* hundred percent of the rated core thermal power). However, in accordance with Amendment No. 3 and the revised Attachment 1 to License DPR-70, the amended license is conditioned to provide a sequential approach to full power

which takes into account a series of incomplete construction i terns,.

preopera.tional tests, startup tests and other items, and provides for further Commission approval at various stages of these activities

Other changes include (1) the requirement for a long-term means of providing overpressure protection; (2) the temporary limitation of power operation to twenty percent of rated core power until the ECCS performance is.reevaluated by modeling the upper head temperature

as the hot .leg temperature; (3) the condition that Facility Operating License.No. DPR-70 is subject to the outcome of the proceedings in Natural Resources Defense Council. v. NRC (D.C. Circuit, July 21, 1976)

Nos .. 74,-1385 and 74-1586,, and (4) changes* to the Appendix A Technical Specifications, in response to your request dated November 81 1976.

Facility Operating License No. DPR-70 initially contained several conditions relating to environmental matters. Since these conditions

.are included in the Appendix B Technical Specifications, they have been deleted from the li~ense proper."

Facility or Procedure Changes Requiring NRC Approval There were no facility or procedure changes during the report year that required prior approval by the Nuclear Regulatory Commission .

Tests and Experiments Requiring NRC Approval During this reporting period, Public Service Electric and Gas Company received approval from the Nuclear Regulatory Commission to conduct

initial core loading and initial criticality, perform zero power physics

.testing, and. perform the power ascension program. A summary report of

the tests and. test results is contained in the following paragraphs.

1.. Initial. Core Loading

Core load. commenced at 2.226 hours0.00262 days 0.0628 hours 3.736772e-4 weeks 8.5993e-5 months on August 17, 1976 and was completed seventy-nine hours later at 0456, August 21, 1976. Though the overall loading.effort proceeded smoothly, several short duration delays occur-red. during the. loading... Failure of the transfer system air motor on two occasions caused suspension of loading for a total of 13 hours1.50463e-4 days 0.00361 hours 2.149471e-5 weeks 4.9465e-6 months , while loss of the.fuel handling bridge position indication caused an additional

3. hour delay.. During various phases of loading, failures of permanent

and temporary.source range-channels, difficulty with gripping a fuel assembly with: the manipulator crane mast, and loss of underwater lighting took. place with little effect on the total fuel loading time. On com-pletion of loading, a video core scan was performed to verify and document the correct location and orientation of all fuel assemblies .

2. SUP 52 - Postponed Phase II Tests and Retests The following tests which were scheduled, but not performed, during hot functional testing, were performed as plant conditions permitted during the periods of cold and hot shutdown.testing. All results met

the specified acceptance criteria.

a. Pressurizer Relief Line High Temperature Alarm

b. Steam Generator Blowdown Flow Control

c. Operation o-f Nos. 11 and 12RH29 Valves d.. RHR Pµmp Motors Winding Temperatures

e.

f.

g.

No. 11 RCP No. 3 Seal Leakage RCS RTD Cross Calibration Pressurizer and Pressurizer.Spray Line Snubber Operation

h. Pressurizer Relief Line Operational Hydrostatic Test

i. Pressure Drop Across Nos. 11 and 12 Mixed Bed Demineralizers

-* 3. SUP 70.1 - Reactor Coolant Leakage Test Two Operating. Department Surveillance Procedures made up this test whereby RCS leak rate and RCP.controlled leakage was determined.

With the data accumulated over a three hour* period, the calculated RCS leak rate of 0 .. 35 gpm was obtained, well within the 1.0 gpm Technical Specification limit.for unknown leakage.

The first measurement of controlled leakage to the Reactor Coolant pumps resulted in an unacceptable value of 50.9 gpm (Technical Specification

limit of 40 gpm). After adjustment of the seal injection throttle valves,. an acceptable test was performed with controlled leakage cal-culated to be. 37. 05 gpm *

-12.-

4. SUP 70.2 RTD Bypass Flow Verification During conduct of.this test, it was determined that No. 14 hot leg RTD bypass loop flow did not meet the minimum flow requirements of 152.1

gpm, assuming a o.* 5 second transport time contribution to the overall RTD. response time.. Communication with Westinghouse revealed that the latest design assumptions. allotted 1.0 seconds, rather than 0.5* seconds, for by.pass loop coolant transport time. With this resolution, all test objectives* and. acceptance criteria were met *

5*. SUP 70 *.3 Reactor Coolant Flow Coastdown Measurements This.test verified* the validity of the safety analysis assumptions on the rate of reactor coolant flow changes due to various combinations of reactor coolant pump trips. Flow.coastdowns* were performed and analyzed

for 2/ 4, 4/ 4, 2/ 3 and 3/3 pump trip. conditions. In addition,. the delay times for low flow, undervoltage, and underfrequency trips, associated

.with the loss of flow accident, were measured. All testing results met the acceptan~e criteria. *

6. SUP 70.. 4 Pressurizer Spray and Heater Capability and Continuous e .Spray. Setting The spray and heater effectiveness tests proved function of the system as designed. *The temperature of.one of the two continuous spray lines could.not be increased above the low temperature alarm point. The alarm point was reset to reflect the lower temperature .

7.. SUP 70 .. 5 Reactor Coolant System Flow Measurement Flow measurements were performed with various combinations of pumps operating ...

With all pumps operating, loop flows were found to be 99,250, 97,AOO, 100,000 and 99,050 gpm for loops 11 thru 14 respectively,

which is above the design~_limit of 88,.500 gpm/loop.

8. SUP 70. 6 Rod Pos.i tion Indication System Ver.ification of satisfactory performance of indication, alarm and con-trol functions.for each control. rod was accomplished through this

procedure with acceptance criteria being met.

9. SUP* 70. 7 Roc;i Drive Mechanism Timing Mechanism timing tests were performed at both cold and hot conditions.

Test resul.ts. were as predicted except for the* stepp:ing traces of the

drive* mechanism.for rod 2D5 in core location H-8. This drive mechanism is an. "*add-on~',. the f.if.th. mechanism to be supplied power from a cabinet basically designed for four drive mechanisms.

Other Changes, Tests and Experiments

Plant Design Change ED-0004

Plant Design Change ED-0004 entitled "Chilled Water System -

Thermowells" has been completed * . The completion of this change resulted in the relocation, and a change in the type of thermo-wells used in three locations within the Chilled Water System .

As a result of this change, a reduced chilled water temperature lag time was realized .

.The safety evaluation for this change determined that there were*

no unresolved safety questions involved .

Plant Design Change ED-0008 Plant Design Change ED-0008 entitled "Replacement of RMS Valves 1VC7 Through 1VC14" has been completed. This change was required in order to allow the Radiation Monitoring System to operate

within it's design requirements. Specifically., the size of the containment sample valves was changed from 3/4" to l" thus improving sample flow.

The safety evaluation for this change considered it not to be an unreviewed safety question.pursuant to Section 10CFR50.59

Plant Design Change ED-0017 entitled "1RH26 Extension Yoke" has been completed. This change was made in order to raise the 1RH26 valve operator above the LOCA "flood~level" within the

reactor containment. A yoke ex~ension was added to raise the valve operator.

The safety evaluation for this change, pursuant to Section 10CFR50.59, did not involve an unreviewed safety question.

e

p1*a*nt Desig*n: Cha*n*g*e En-0*018

,Plant Design Change ED-0018 entitled "Movement of Reactor Vessel Head Access Platform" has been completed. The movement of this platform was only a minor arrangement change. Primarily, the change was made in order to avoid interference with the storage e position of the upper internals removal tripod.

The engineering safety evaluation made for this change determined that there was no unreviewed safety question involved.

Pl'ant Design: Cha*nge* ED-0019

Plant Design Change ED-0019 entitled "Service Water Piping -

Reactor Containment" has been completed. This change required

~16-

the replacement of flexible metal service water connections to the Containment Fan Coil Unit Motor Coolers with* a rigid con-

tinuous pipe. Replacement of these connection pipes to the motor coolers was made in order to minimize the possibility of rupturing the flexible service water lines, due to pressure transients from a dynamic water hammer observed during certain control valve manipulations.

I As this Design Change does not functionally alter the service water piping system, it does not present an unreviewed safety question as defined in 10CFR50.59.

Plant Design Chan*ge ED-0020

Plant Design Change ED-0020 entitled "Nuclear Instrumentation -

Instrument Power Feed" has been completed. This change replaced a 0.5 KVA type LVR Solatron regulator with a 0.25 KVA Solatron CVS regulator in the power feed for Channel IV nuclear instru-mentation. As a result, the interaction between the regulator and the output stage of the nuclear instrument was reduced *

LICENSEE EVENT REPORTS

During this reporting period, a total of thirty-one (31) events occurred which resulted in Licensee Event Reports. Each of these events occurred at a reactor power level of less than 20% design power and are not applicable to or included in this report .

OTHER EVENTS OF INTEREST

Main. Steam Generator Safety Valves - Setpoint Change Following certain Unit #1 Startup Tests, there were indications

that several Main Stearn Generator safety valves were weeping.

In order to correct this problem, the vendor was requested to lap the valve seat for each safety valve. In addition, the vendor was queried as to whether or not seat lapping would affect the lift pressure. The vendor's response was that this action

would not affect the lift setpoint

Upon the completion of seat lapping, Unit #1 was again brought

. to normal operating temperature. During the subsequent heatup, several Main Stearn Generator safety valves lifted at a below normal pressure. Accordingly, all steam generator safety valves

were tested pursuant to Maintenance Department Procedure M9E, "Stearn Generator Safety Valve Testing". After testing, nine (9) out of twenty (20) safety valves were found to have needed minor lift setpoint adjustments.

Fuel Perf orrnance

,. During the receipt of the initial 193 fuel assemblies (October 1975 -

January 1976), a small percentage*o"f assemblies showed minor discolora-tion, which was termed rust, on the top nozzles. After an on-site inspection and subs.equent investigation by Westinghouse, it was concluded that the rust was cosmetic in nature and there was no opera-tional impact. The vendor hand cleaned all observable discolorations.

Initial criticality was achieved on 12-11-76. As of 12-31-76, the

core had a total exposure of 1600 MWD (18 MWD/MTU) .

During hot zero power physics testing, a core quadrant tilt of 2.5 to 4.5%, depending on control rod position, was measured. The tilt appears to be centered about.fuel assembly locations defined by the intersections of columns B, M, N and rows 13 and 14. These assemblies

are running 10 to .15 per.cent above the predicted relative power

Technical specifications do not address radial power tilts below 50%

power. Hot channel factors are monitored above 5% power for Technical Specification comp'Iiance. The effect of the tilt on F and F liH will be rnoni to red. . xy

At higher power levels, the leveling effect of xenon and doppler will tend to minimize the tilt. Core exposure will also aid in flattening the flux
