7590-01 In the Matter of FLORDIA POWER AND LIGHT COMPANY (Turkey Point Plant Unit Nos.
3 and 4)
UNITED STATES OF AMERICA NUCLEAR REGULATORY COMMISSION Docket Nos. 50-250 and 50-251 ORDER FOR MODIFICATION OF LICENSE I.
Flordia Power and Light Company (the licensee) is'he holder of Facility Operating License Nos.
DPR-31 and DPR-41 which authorize the operation of the Turkey Point Plant, Unit Nos.
3 and 4 (the facilities) at steady-state power levels not in excess of 2200 megawatts thermal.
The facilities are pressurized water reactors (PWRs) located at the licensee's site in Dade County, Florida.
II.
By letter dated October 12, 1983, supplemented on October 13, 1983, the licensee requested relief from its existing technical specifications requirement to go to cold shutdown because only one residual heat removal (RHR) loop is operable.
The 4B RHR pump motor failed during routine testing at Turkey Point Unit 4 at 11:35 a.m., October 11, 1983.
The failure was such that a major repair effort of the motor is required.
The licensee contacted the motor vendor, and other utilities utilizing simil~~ equipment and has determined that due to the 83102402b 08000250 g 83iOi~
PDR AMCK
>DR P
~ IP unique design, and age of the component, no replacements or spares are available.
The motor vendor has service people on-site and repairs are in progress.
The current technical specifications require that the unit be placed in hot shutdown within 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> of the RHR pump being out of service, and in cold shutdown within an additional 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />.
The plant has been placed in hot shutdown as required.
At issue is the subsequent requirement to go to cold shutdown.
The licensee has requested emergency relief from the Turkey Point Technical Specifications, to permit extended operation in mode 4 (hot shutdown) on a one time basis while the inoperable Unit 4 RHR pump is being repaired.
The requested relief is an interim requirement to allow operation with the reactor shutdown and Tavg between 350'F and 200'F for a period up to 30 days with one residual heat removal pump out of ser vice.
The staff has considered the consequences of going to cold shutdown and the potential loss of the remaining RHR loop.
We have concluded that operation in hot shutdown with the reactor coolant system (RCS) average temperature less than 350'F while the inoperable pump is being repaired would be more prudent.
The basis for our conclusion is contained in our attached Safety Evaluation.
In view of the foregoing, I have determined that a temporary change in the licensee's technical specifications to require the licensee to maintain the reactor coolant system Tavg between 350'F and 200'F when one residual heat removal pump is inoperable for a period up to 30 days is required in the interest of public health and safety and, therfore, should be made effective immediately.
Accordingly, pursuant to Sections 103, 161i, and 16lo of the Atomic Energy Act of 1954, as
- amended, and the Commission's regulations in 10 CFR Parts 2
and 50, IT IS HEREBY ORDERED EFFECTIVE IMMEDIATELY: Technical Specification 3.4.1b is modified as set forth in Attachment 2 of this Order.
IV.
The licensee may request a hearing on this Order within 20 days of the date of publication of this Order in the Federal Re ister.
Any request for a hearing shall be addressed to the Director, Office of Nuclear Reactor Regulation, U. S. Nuclear Regulatory Commission, Washington, D.C.
20555.
A copy shall also be sent to the Executive Legal Director at the same address.
A RE(VEST FOR HEARING SHALL NOT STAY THE IMMEDIATE EFFECTIVENESS OF THIS ORDER.
If a hearing is to be held, the Commission will issue an Order designating the time and place of any such hearing.
If a hearing is held concerning this Order, the issue to be considered at the hearing shall be whether the licensee should comply with the requirements set forth in Section III of this Order.
This Order. is effective upon issuance.
FOR THE NUCLEAR REGULATORY COMMISSION Dated at Bethesda,
- Maryland, this 14th day of AwWr, 1983.
