Dear Sir:

As a result of the Seabrook Station Technical Specification Improvement Program, the Loose Parts Monitoring System Technical Specification has been removed from the Seabrook Station Technical Specifications and the requirements for operability and surveillance have been included in FSAR Section 16.3. This change has necessitated revisions to Sections 1.8 and 4.4.6.4 of the FSAR.

Enclosed for your information are annotattd FSAR pages showing the appropriate changes. These changes will be fornally updated in future amendments to the FSAR.

Very truly yours,

SB 1 & 2 Amendment 52 FSAR December 1983 direction, and with the advice of, experienced personnel familiar with the site and regional geology. He main exception to compliance with the guide was in meeting the general guidelines for subsurface explorations. These explorations were carried out to adequately assess the foundation require-ments based on the complexity of the anticipated subsurface conditions. This is further discussed in Subsection 2.5.1 and its associated appendices.

Regulatory Guide 1.135 Normal Water Level and Discharge at (Rev. O, 9/77) Nuclear Power Plants ne structural design criteria for normal ground and surface water levels

! comply with Regulatory Guide 1.135 by establishing the maximum ground and surface water levels at safety-related structures and facilities at +20 feet MSL (plant grade). Elevation +20 feet MSL is above both the maximum recorded ground water level and also above the postulated probable maximum surge still water level.

Wave runup and overtopping of the protective revetment would occur during the probable maximum surge which would cause ponding on the site of approxi-mately 0.6 feet. All safety-related structures are protected against this site ponding level.

For further discussion, refer to Section 2.4.

SB 1 & 2 Amendment 55 FSAR July 1985 t

Reg. Guide Position Discussion C.I.g The LPMS is designed to operate under normal environmental C.4.k conditions.

The LPMS (excluding the recording equipment) has been seismi-cally qualified to IEEE 344-75 to be functional up to and including the Operating Basis Earthquake (OBE). The LPMS sensor, charge converter, and system cabinet are seismically supported.

C.I.h The LPMS will be included in the Seabrook surveillance and maintenance program. Any components that are not qualified for 40 years will be replaced prior to the end of their qualified life. Maintenance actions will be performed in accordance with approved procedures. The documented mainte-nance history results will be maintained and evaluated over the life of the plant.

C.I.i Recognition of a faulty channel is easily identified by a blinking LED condition. All Control Room electronics are rack-mounted, designed for the ease of replacement or repair in the event of a malfunctioning channel.

C.4.a Sensor Type: Piezoelectric Accelerometer Mounting tolerances and criteria for determining sensor loca-tion have been provided by Westinghouse. This information is presently under review and will be furnished six months prior to fuel-load.

C.4.c Anticipated major sources of external and internal noises are pump starts, reactor trip, and control rod stepping.

C.4.d By meeting the criteria as defined in position C.3, the acquisition of quality data is ensured.
