Re: Turkey Point Units 3 and 4 Docket No. 50-250 and 50-251 R sistance Tem erature Detector B ass Elimin, i n Pro'ect By letter L-90-6SA, dated September 13, 1990, Florida Power and Light (FPL) submitted a request to amend the Turkey Point Technical Specifications by eliminating the Resistance Temperature Detector (RTD) Bypass. Subsequently, the NRC and FPL met on November 27, 1990, to discuss the above submittal. At this meeting FPL agreed to review initial implementation testing and subsequent periodic testing of RTD response time and the T,median signal selector, and initial and subsequent RTD cross-calibration.

In addition to the initial RTD cross-calibration, RTD response time testing, and the T,median signal selector testing which will be performed as part of the normal start-up and turnover process, FPL will perform periodic testing as described below.

FPL will perform RTD response time testing meeting the following criteria:

o In-situ response time testing of the RTDs will be performed using the Loop Current Step Response method.

o The above testing will be performed for the three channels once every three refueling cycles on a staggered test basis, with a separate channel being tested during each refueling cycle (1S months).

FPL willperform cross-calibration of all RTDs during each refueling cycle by comparing the installed RTDs to each other.

FPL will test the T,median signal selector quarterly.

The above testing does not require a change to the proposed license amendment. Procedures implementing this testing will be issued consistent with the system start-up schedule.

Should there be any questions, please contact us.
