Re:

St. Lucie Unit 2 Docket No. 50-389 Relief from Parts of ASME Section XI By letter dated January l3, l986, the NRC denied a Florida Power

& Light Company (FPL) relief request from the requirements of IWP-4600 of ASME Section XI regarding flow measurement.

By letter dated October l3, l986, FPL submitted a

revised request for relief from performing quarterly flow measurements for certain pumps as specified in the l980 Edition through the Winter l980 Addenda of Section XI. As a basis for this request, FPL showed that flow measurement cannot be performed for some of the pumps because the pumps do not contain flow measurement devices and that quarterly flow measurement for the remaining pumps is impractical without design modifications to permit performance of the flow measurement tests under Section Xl of the ASME Code.

By letter dated February IO, l987, the NRC denied FPL's revised relief request and directed FPL to install certain flow measurement devices for the pumps by the next refueling outage for St. Lucie Unit 2. Also, in that same letter, FPL was given the opportunity to request an appeal meeting.

On March 4, l987, FPL met with the NRC to appeal the decision in NRC's letter of February IO, l987.

At this meeting, FPL restated its position that quarterly flow measurements were impossible or impractical absent design modifications, and that FPL was not required under IO CFR 50.55a(g) to modify its design.

Following the FPL appeal presentation, the NRC requested that FPL provide NRC with an enhanced technical evaluation which addresses the impracticality of performing flow measurements specified in Section XI of the ASME Code (including an evaluation of the adequacy of the tests proposed by FPL in its October l3, l986 letter and an evaluation of whether installation of the flow measurement devices identified in the NRC's letter of February IO, l987, would provide additional assurance of pump operational readiness).

The purpose of this letter is to transmit the requested enhanced technical evaluation.

The revised relief requests will be submitted to the NRC at a later date.
