~Back round The Final Safety Analysis Report, Section 3.7.4, describes the seismic monitoring instrumentation system for the Harris Nuclear Plant installed to meet the guidance provided in NRC Regulatory Guide 1.12, "Instrumentation for Earthquakes," Revision 1, April 1974. Operability of the seismic instrumentation ensures that sufficient capability is available to promptly determine the magnitude of a seismic event and evaluate the response of those features important to safety.

This. capability is required to permit comparison of the measured response to that used in the design basis for the facility to determine ifplant shutdown is required pursuant to Appendix A of 10 CFR Part 100. The NRC's acceptance of the Harris Nuclear Plant seismic monitoring instrumentation program is documented in Section 3.7.4, NUREG-1038, "Safety Evaluation Report related to the operation of Shearon Harris Nuclear Power Plant, Units 1 and 2," dated November 1983.

d Ch The proposed change to Technical Specification (TS) Table 3.3-7, Seismic Monitoring Instrumentation, and TS Table 4.3-4, Seismic Monitoring Instrumentation Surveillance Requirements, will correct the location described for one of the three Triaxial Peak Accelerograph Recorders. Specifically, the recorder connected to the Reactor Coolant System piping is installed on Loop 2 (Loop B), and not on Loop 1 (Loop A).

Basis The purpose of the seismic monitoring instrumentation system is to sense, alarm, and record information on seismic disturbances to the ground and selected plant structures caused by an earthquake or other violent event. The system is composed of active and passive seismic monitors. The active portion of the system provides alarms for immediate identification of a seismic event and recordings that can be evaluated for actual shock acceleration levels and potential plant damage. The passive portion of the system provides permanent mechanically etched records of the seismic event. Information gained from the monitoring system permits evaluation of seismic effects on structures and equipment.

Page El-1 .

It ENCLOSURE TO SERIAL: HNP-96-087 As part of the passive portion of the seismic monitoring instrumentation system, the Triaxial Peak Accelerograph Recorders are single unit, triaxial, orthogonal, passive components that inscribe a permanent record on a small metal plate by a diamond-tipped stylus. This type of recording is desired due to its ability to function with total independence of any other system or power supply.

Data are obtained after a seismic event by removing the plates from the field sensors, examining them under magnification, and measuring the distance from a base scribe to the peak of the active scribe.

Technical Specification Table 3.3-7, Seismic Monitoring Instrumentation, and Table 4.3-4, Seismic Monitoring Instrumentation Surveillance Requirements, describe the locations of the three Triaxial Peak Accelerograph Recorders. The locations described for the recorders located on the Steam Generator "A" pedestal and in the Reactor Auxiliary Building agree with current design drawings. The location for the third recorder is described as "Reactor Coolant Pipe (Loop 1)," whereas the recorder is actually installed on reactor coolant piping connected to Loop 2 (Loop B). The early plant design showed the recorder on Loop 1, but this was later revised, and the actual installation was on Loop 2. Current plant design drawings show the correct location, but the discrepancy with Technical Specifications was not identified. However, the loop designation is not material to either the Technical Specifications or compliance with Regulatory Guide 1.12. Regulatory Guide 1.12 states only that one triaxial peak accelerograph should be provided at a "selected location on the reactor piping." Therefore, this proposed change is administrative and does not involve any physical alterations to plant equipment.

NPF-63 REQUEST FOR LICENSE AMENDMENT TRIAXIALPEAK ACCELEROGRAPH LOCATION 10 CFR 50.92 EVALUATION The Commission has provided standards in 10 CFR 50.92(c) for determining whether a significant hazards consideration exists. A proposed amendment to an operating license for a facility involves no significant hazards consideration ifoperation of the facility in accordance with the proposed amendment would not: (1) involve a significant increase in the probability or consequences of an accident previously evaluated, (2) create the possibility of a new or diffe'rent kind of accident from any accident previously evaluated, or (3) involve a significant reduction in a margin of safety. Carolina Power & Light Company has reviewed this proposed license amendment request and determined that'its adoption would not involve a significant hazards determination. The bases for this determination are as follows:

Pro osed Chan e The proposed change to Technical Specification (TS) Table 3.3-7, Seismic Monitoring Instrumentation, and TS Table 4.3-4, Seismic Monitoring Instrumentation Surveillance Requirements, will correct the location described for one of the three Triaxial Peak Accelerograph Recorders. Specifically, the recorder connected to the Reactor Coolant System piping is installed on Loop 2 (Loop B), and not on Loop 1 (Loop A).

Basis This change does not involve a significant hazards consideration for the following reasons:

1. The proposed amendment does not involve a significant increase in the probability or consequences of an accident previously evaluated.

These recorders are passive components which serve only a recording function. They can neither initiate an accident nor serve to mitigate accident consequences. The proposed change serves only to correct the location, commensurate with design documents, for one of the three recorders described in the Technical Specifications. Accordingly, this change is administrative in nature. Therefore, there would be no increase in the probability or consequences of an accident previously evaluated.

ENCLOSURE TO SERIAL: HNP-96-087

2. The proposed amendment does not create the possibility of a new or different kind of accident from any accident previously evaluated.

The proposed correction is an administrative change to correct the location of a recorder currently described in the Technical Specifications. No physical alterations to plant equipment are being made, and there will be no changes that alter how any safety-related system performs its function. Therefore, the proposed changes do not create the possibility of a new or different kind of accident from any accident previously evaluated.

The proposed amendment does not involve a significant reduction in the margin of safety.

Technical Specification Bases 3/4.3.3.3 specify the acceptance level for seismic instrumentation as "consistency" with the recommendations of Regulatory Guide 1.12.

Since the regulatory guide states only that one recorder should be provided at a "selected location on the reactor piping," it is not material whether it is installed on Loop 1 versus Loop 2. Therefore, the proposed change does not affect a margin of safety as defined in the Bases to the Technical Specifications.

NPF-63 REQUEST FOR LICENSE AhKNDMENT TRIAXIALPEAK ACCELEROGRAPH LOCATION ENVIRONMENTALCONSIDERATIONS 10 CFR 51.22(c)(9) provides the criterion for and identification of licensing and regulatory actions eligible for categorical exclusion from performing an environmental assessment. A proposed amendment to an operating license for a facility requires no environmental assessment if operation of the facility in accordance with the proposed amendment would not: (1) involve a significant hazards consideration; (2) result in a significant change in the types or significant increase in the amounts of any efHuents that may be released offsite; (3) result in a significant increase in individual or cumulative occupational radiation exposure. Carolina Power &: Light Company has reviewed this request and determined that the proposed amendment meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment needs to be prepared in connection with the issuance of the amendment. The basis for this determination follows:

Pro osed Chan e The proposed change to Technical Specification (TS) Table 3.3-7, Seismic Monitoring Instrumentation, and TS Table 4.3-4, Seismic Monitoring Instrumentation Surveillance Requirements, will correct the location described for one of the three Triaxial Peak Accelerograph Recorders. Specifically, the recorder connected to the Reactor Coolant System piping is installed on Loop 2 (Loop B), and not on Loop 1 (Loop A).

Basis The change meets the eligibility criteria for categorical exclusion set forth in 10 CFR 51.22(c)(9) for the following reasons:

1. As demonstrated in Enclosure 2, the proposed amendment does not involve a significant hazards consideration.

The proposed amendment does not result in a significant change in the types or significant increase in the amounts of any efHuents that may be released offsite.

The proposed amendment corrects the location described in the Technical Specifications for one of the three Triaxial Peak Accelerograph Recorders. This change will neither introduce any new equipment nor will it require any existing equipment or systems to Page E3-1

ENCLOSURE TO SERIAL: HNP,-96-087 perform a different type of function than they are currently designed to perform. As such, the change cannot affect the types or amounts of efHuents that may be released offsite.

The proposed amendment does not result in a significant increase in individual or cumulative occupational radiation exposure.

The proposed correction will not result in any additional or changed sur veillances or testing. Therefore, the amendment has no effect on either individual or cumulative occupational radiation exposure.
