Mr. Vincent S. Noonan, Project Director PWR Project Directorate No. 5

References:

(a) Construction Permits CPPR-135 and CPPR-136, Docket Nos. 50-443 and 50-444 (b) PSNH Letter (SBN-1098), dated June 6,1986, " Accident Monitoring Instrumentation Review and Compliance with Regulatory Guide 1.97", J. DeVincentis to V. S. Noonan

Subject:

Accident Monitcring Instrumentation Review and Compliance with Regulatory Guide 1.97

Dear Sir:

In discussions with the NRC Staf f it was agreed that the Main Plant Vent Stack Noble Gas Radiation Monitor (FSAR Tabic 7.5-1, Item E7) provides the primary indication for detection of significant releases or breach of the containment.

The Containment Enclosure Noble Gas Radiation Monitor (FSAR Table 7.5-1, Item C-13) is backup indication that assists the operators in identifying the location of a release that has been identified by the Main Plant Vent Stack Monitor.

Since backup Type C variables are considered Design Category 3 we are revising the FSAR to reflect this change.

Attached are marked-up copies of FSAR Table 7.5-1, sheet 12 and page 7A-9 that reflects the change of the Containment Enclosure Noble Gas Radiation Monitor from Design Category 2 to 3.

These changes will be included in a future amendment to Seabrook's FSAR.

We trust that the enclosed is acceptable and request that this be reflected in the next supplement to Seabrook's SER.

Very truly yours, 8607220418 860718
