Mr. Ashok C. Thadani, Director PWR Project Directorate NS Division of PWR Licensing B U. S. Nuclear Regulatory Commission Washington, D. C. 20555
Dear Mr. Thadani:
RE:
St. Lucie Unit 2 Docket No. 50-389 Extension of Interim Relief From Parts of ASME Section XI By letter dated March 11, 1986, Florida Power 4 Light Company (FPL) requested an extension of the Interim Relief granted in your January 13, 1986 letter, which directs modification of St.
Lucie Unit No.
2 this outage to provide for flow measurement of certain pumps.
At the request of NRC staff, a
telephone conference was held March 27, 1986 to discuss and describe the modifications and schedules involved.
The purpose of this letter is to provide additional information (see Table 1
attached) on the modifications that would be needed to support bypass flow measurements on the pumps in question.
FPL requests that NRC grant relief from the testing requirements for the duration of Cycle 3.
In order to support unit
. start-up for Cycle 3, we r equest NRC approval by April 30, 1986.
\\
FPL check number 0985 is attached as remittance for the review fee specified in 10 CF R170.21.

Modification Location I~ s AFW (2A, 2B, 2C)
Descri tion Install a camen flow rreasuremnt device in the existing bypass line to the Condensate Storage Tank.
This pipe run is mlstly underground, but a short section is accessible under a missile-shield in the pmy area.
However, there is not enough rocm in the pipe trench to install equiprent, so a new missile-shielded pipe would have to be run outside the trench.
A 30-ft pipe run would be needed for flow stability, and would contain the necessary
- flanges, valves, instrwents etc.

Install a camen flow rn asurenent device in the existing 6-in recirculation line to the Refueling Water Tank.
However, this 6-in line is too large to rn asure the flows in question
(
50 gpn}, so a new 2-in bypass line (and associated flanges, valves, instr'.ntation, etc.) would have to be installed.
The rrost likely location would be the pipe tunnel in the Auxiliary Building.

The existing camen 2-in cross-tie nay be long enough to install the necessary
- flanges, valves, instrwentation, etc. Havever, instrumentation procurerrLnt-lead tirras are too long to support installation in the short term.

A flev naasurerrent device could be installed at the Boric Acid Makeup Station in the Auxiliary Building.
- However, the piping is insulated and heat traced
( 20,000 ppn boron acid solution), which carplicates the modification process.
