Dear Mr. Bowling:

In an April 1,1998, letter, Northeast Nuclear Energy Company (NNECO) requested a license amendment to revise the Millstone Unit 3 licensing basis by adding a new sump pump subsystem to address groundwater inleakage through the containment basemat.

In order for the staff to complete its review of NNECO's request, the staff requires additional 1

information. Please respond to the enclosed request for additionalinformation as soon as possible.

Sincerely, Original signed by:

v REQUEST FOR ADDITIONAL INFCRMATION MILLSTONE NUCLEAR POWER STATION. UNIT 3 DOCKET NO. 50-423 1

1.

In the submittal dated April 1,1998, NNECO states that in the proposed revision to the Final Safety Analysis Report Table 3.2-1, the containment recirculation sump piping is listed as ANS Class 3; however, the Code Class is denoted as N/A (not applicable).

Also, the table does not contain the other components in the engineered safety features (ESF) building sump pumping subsystem, which is a necessary system to assure operation of the recirculation spray system following a loss-of-coolant accident (LOCA).

This is inconsistent with Regulatory Guide 1.26 guiriance, which states that such systems having an important safety function for post-accident containment heat removal should be categorized Quality Group C, which should be designed to American Society of Mechanical Engineers (ASME) Code Class 3 requirements. Provide the justification for not designating these safety related components as ASME Code Class 3, 2.

Because the ESF building sump pumping subsystem pumps and valves are used to mitigate the consequences of a LOCA, they should be included in the plant inservice testing (IST) program and periodically tested in accordance with the applicable edition of l

the ASME Code. Provide the justification for not including these safety-related components in the IST program.

3.

Two designated air compressors are to be used for motive power for the ESF building sump pumps and should be included in the plant Quality Assurance (QA) program in order to assure proper operation to accomplish their safety-related function. Describe the QA requirements for these air compressors.

4. to NNECO's license amendment request (List of Regulatory Commitments) states that two air compressors are staged in designated locations, and will be maintained and periodically tested to ensure their availability. Identify their designated locations and also indicate how their safety against tornado missiles is ensured.

l S.

Provide information regarding the method and the ground motion input used in the seismic qualification of the sump pumps.
