SUMMARY

OF CHANGES, TESTS, AND EXPERIMENTS FOR THE HOPE CREEK GENERATING STATION November 1994 f

The following items have been evaluated to determine:-

-5 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 - 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.

l The 10CFR50.59 Safety Evaluations showed'that these items did not create a new safety hazard to the plant nor did they' affect the i

safe shutdo.n of the reactor.

These items did not' change the.

1 plant affluent releases and did not alter the existing environmental impact.

The 10CFR50.59 Safety Evaluations determined that no unreviewed safety or environmental questions are involved.

m Desian Chances Summary 21 Safety Evaluation 4$C-00032 Pkg 3 & 4:

These Design Change Packages included the replacement of the non safety Reactor Protection System (RPS) alternate feed BUS transformers with "ISOREG" 25 KVA Regulating Transformers.

The "ISOREG" Regulating Transformer will improve the stability of the 120VAC power supplied to the Electrical Protection Assemblies (EPA's) and ri '.uce noise in the system.

These installations do involve changing the EPA's existing UV/OV setpoints.

The RPS alternate feed power with "ISOREG" Regulating Transformer will improve the reliability of the 120VAC power supplied to the EPA's and prevent their tripping due to spurious undervoltage, overvoltage, and frequency swings.

The system noise is also reduced.

Therefore there are no credible failure modes created as a result of these change packages.

Therefore, this DCP does not increase the probability or consequences of an accident previously described in the SAR and does not involve any Unreviewed Safety Question.

Procedure Summary 91 Safety Evaluation Procedure NC.NA-AP.ZZ-0065(Z) Rev 2:

This procedure which governed Nuclear Department Resource Allocation has been deleted as a Nuclear Department Administrative Procedure.

A new Nuclear Department Business Procedure was created to cover this information.

The Operational Quality Assurance Program does not apply to this procedure.

Although this procedure is briefly mentioned in the UFSAR (Sect 13.5.1) it performs no function relative to the safe operation of Hope Creek Station.

Therefore, this Procedure revision does not increase the probability or consequences of an accident previously described in the SAR and does not involve an Unreviewed Safety Question.

Other gummary 91 Ea f ety Evaluation UFSAR Change 94-43:

These UFSAR Changes are the result of the UFSAR Change 94-25 wherein the terms Type "A" and Containment Intergrated Leakage Rate Test (CILRT) were redefined and removes the ambiguity as to whether these actions are acceptable.

This change allows the Type "A" test to be completed in 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br />.

It provides for leakage monitoring of the CRD lines anytime during the CILRT as long as the reactor vessel and non-seismic portion of the system is vented and containment is pressurized, not just during the Type "A"

test.

It identifies the purpose of the Type "A" test as the measurement of air leakage from the containment.

It requires the Type "C" testing of penetrations isolated from the Type "A" test be used to adjust the Type "A" measured leakage rate.

It removes the requirement to operate drywell chilled water during the Type "A" test, but requires that it be maintained available if needed which will allow more options to maintain a stable containment atmosphere.

The dFSAR changes do not revise limits or acceptance criteria contained in the Technical Specifications (TS).

Margins of safety as defined in the basis for TS's remained unchanged.

The Type "A"

test and supplemental test acceptance criteria remained unchanged.

The Wpe "A" test will continue to ensure that the primary containment atmosphere (air) leakage rate does not exceed 0.375 percent per day which provides 6 margin for operational degradation.

Therefore, this UFSAR Change does not increase the probability or consequences of an accident previously described in the SAR and does not involve an Unreviewed Safety Question.

Safety Evaluation 1C-8-501:

"C" Traveling Screen was replaced with a refurbished screen.

To replace this screen a 3" ASME Class 3 stainless steel line was cut to facilitate the screen removal.

The 3" line was rewelded and a final weld examination, Liquid Penetrant Test (PT), was performed and resulted in two indications.

Both indications were in the reinforcement (crown) portion of the weld.

Both indications were removed by filing and a PT was performed of the excavated site by the welder.

The PT on the excavated area was satisfactory and the welder replaced the reinforcement portion of the weld.

A final weld PT was performed by a qualified individual with satisfactory results.

All the steps of this weld repair followed the rules set forth by the ASME Code except the PT on the excavated area which was performed by the welder who was not qualified to ASME Section XI IWA-2300 requirements.

This screen was placed inservice for approximately 7 months until the QA engineer reviewed the work package and identified a problem with the qualifications of the individual performing the excavation PT.

The weld was re-excavated and satisfactorily repaired.

UFSAR Chapter 15 accident analysis discusses total failure of this one wold on one of three spray wash pipes of the "C" traveling screen could cause river debris to be carried over the screen and the "C" Service Water Pump suction.

The debris would travel through the pump and impinge on the "C" strainer mesh.

The "C"

strainer is designed to remove debris from river water.

If the strainer becomes overloaded with debris, control. room indications will alert the operators by overhead annunciator and by CRIDS points which would indicate an increase differential pressure across the service water strainer.

Therefore, this UFSAR Change does not increase the probability or consequences of an accident previously described in the SAR and does not involve an Unreviewed Safety Question.
