e-d REQUEST FOR ADDITIONAL INFORMATION ENCLOSURE NORTH ANNA POWER STATION, UNIT 2 DOCKET N0.

50-339 NUREG-0578 - Item 2.1.8.b Provide a description of the two high range containment monitors required by our letter of November 9,1979, implementing the lessons Learned item 2.1.8.b of NUREG-0578, and specify the location of these monitors inside containn.ent. The description of the monitcrs should include:

a. type of radiation measured;

b. the range or ranges of the monitors.

If two or more monitors are required to span the range in Table 2.8.1.b.3 of our 8

7 November 9,1979 letter (10 rad /hr total radiation or 10 R/hr photons only), the ranges of the subsystem monitors must overlap (i.e., upper value/ lower value of overlap) by at least a factor of 10;

c. location of and type of readout (continuous and recording);

d. energy response (sensitive 60 kev);

e. calibration frequency and methods (refueling frequency);

f. verification that the monitors are powered separate vital instrumental buses;

g. Verification that the monitors will be operational by full power;

h. verification that the moniors meet the seismic qualification of Regulatory Guide 1.100 (Seismic Category I) and are environ-mentally qualified to survive an in-containment LOCA in 1

accordance with Regulatory Guide <1.89.

The location of the monitors should be shown on plant layout drawings.

The monitors should be 1bcated in a manner as to provide a reasonable assessment of radiation levels inside containment.

Monitors should not be placed in areas which are protected by massive shielding.
