VM 2 81375 S. H. Hanauer, Technical Advisor to the Executive Director for Operations QUESTIONS ON ESP FOR M MILE ISLAND UNIT 2, OL You raised the folicving questions in response to our ESP's for Unit 2.
1.
i&.y are these issues only now being raised?
2.
Given RSP's 01, 02, 03, and 06; should Unit 1 be shut down?
The applicant has consistantly provided narginal responses to our ques ticus. These questions were origin 117 raised in QO and/or Ql, so that we could independently evaluate the adequacy of flood pro-tection as conpared to the accepted design bases. The positions were necessary to either elicit coupleta documentation of the pro-taction or cause an upgrade in the protection to acceptable levels.
RSP-01 addresses only Unit 2 buildings.
RSP-02 discusses sita drainage. Until Unit 2 and surrounding yards are nearer co=pletion there should be no problen for " nit 1.
An emergency procedure could be quickJy enacted for Unit 1 which would take care of any problem and be appropriate for Unit 2.
RSP-03 discusses flood protection for individual safety-relatad.
buildings. The purposes of this position is to obtain design infor-'
mation previously requested.
RSP46 discusses need for assurances with regard to island access during flood-induced emergency shut down. Item was discussed with applicant at sita visit (draft Q1). The applicant assured us that appropriate secticus of emergency plan would be provided to show that all necessary staff would be on the Isimnd before the bridge was threatened. With the understanding that this vould be documented.
we deleted the question (Q1).

- k. 2 6 W5 S. ii. Hanauer Itaa 0-10 is of potential concern as to Unit 1.
The iten addresses the inadequate maintenance of the arrer protection for the levees.
During recent site visits, we observed tiu.t the ar:or is degraded and =ay no longer serve the design safe'.7 function. We have requested that Projects (operating group) coordinate with R0 and ILE require repair and maintenance of the levees within about 2 conths.
If the repair is procptly accomplished, there is no reason to require shut down of unit, and flood protection should not be unduly compromised.
