SUBJECT:
Florida Power Corporation Crystal River Unit #3 Docket No. 50-302
Dear Mr. Stolz:
On December 15, 1976 Florida Power Corporation filed with the Commission a request for relief from the requirements of the ASME Boiler and Pressure Vessel Code,Section XI. Our submittal contained a detailed Inservice Inspection and Testing Program for Crystal River Unit 3.
Based on your review of our December 15th submittal, you granted Florida l
Power relief from the ASME Code requirements pursuant to Section 4.0.5a of the CR#3 Technical Specifications, for the period of time from issu-ance of the facility operating license on December 3,1976, to the start of facility comercial operation. You further requested FPC in Supple-ment No. 3 to the staff's SER dated December 30, 1976 to provide by March 3,1977, for your review, the specific exceptions from the ASME Code requirements determined to be impractical, and the information to support these exceptions. Mr. Boyd's letter of February 1, 1977, formally transmitted to us the specific information your staff needs to make an evaluation of our request for relief pursuant to 10 CFR 50.55a(g) (6) (1).
In response to your request we hereby transmit 43 copies of additional information in support of our request for relief from ASME Section XI requirements that we have determined to be impractical, in accordance with the Comission's guidance letter of February 1,1977. Our program is based on ASME Code Section XI,1974 Edition through summer 1975 Addenda for the period of 20 months following comercial operation
-M-Q-General Office 3201 Tniny-founn s:reet soutn. P O Box 14o42. st Petersburg. Fiorica 33733 813 - 866-5151
Page 2 for the Pump and Valve Testing Program and for the period of 40 months following commercial operation for the Inservice Inspection Dppgram, Enclosures 1 through 4 identify each pump and valve to which the above ASME Code applies and which code requirements of Section XI are con-sidered to be impractical. Also included in our response is an imple-mentation schedule as requested in the Commission's February 1, 1977, letter.
Although the number of specific components for which we seek relief from the ASME Code is small we will require additional time to implement the new code requirements that can be met but are not presently included in our Pump and Valve Testing Program. We hereby request that we be granted until September 3,1977, for complete implementation of the pump testing program based on the new ASME Code and until March 3,1978, for complete implementation of the valve testing program. This additional time for implementation is required in order that our present surveillance procedures can be revised to include the new code requirements from which relief is not being sought. We feel that this additional time will enable an orderly implementation of these new code requirements without compromising in any way the safety of the plant.
Your February 1,1977, letter also requested additional information concerning our Inservice Inspection Program. The baseline classifi-cation of Class 1 and 2 components at CR#3 were Non-Destructive Examined (NDE) per ASME Section XI 1971 Edition through winter 1972 Addenda.
We are presently working with B&W upgrading this baseline information for Class 1 and 2 components into an Inservice Inspection Program based on ASME Section XI 1974 Edition through Summer 1975 Addenda and identifying those areas where code requirements cannot be met. A detailed comparison is also being made between existing plant repair, welding and inspection
- procedures and the requirements of ASME Section XI to identify areas where relief is required. Waiver requests for those code requirements determined to be impractical will be submitted to the Commission on or before April 15, 1977.
Class 3 components and those excludeo from Class 1 and 2 NDE requirements are presently being reviewed to deteraine where hydrostatic and visual inspections per ASME Section XI are impractical.
Waivers for components where these two code requirements are impractical will be submitted to the Commission on or before April 15, 1977.

Page 3 Development of the Inservice Inspection Program for Crystal River Unit 3 based on ASME Section XI, 1974 Edition through Summer 1975 Addenda, will not be finished until October, 1977. This is well in advance of the inservice inspection required for CR#3 which is currently scheduled during the first refueling outage in the fall of 1978.
It is hereby requested that Florida Power be granted waivers from those Code requirements identified in Enclosures 1 thru 4 of this letter in-cluding the implementation dates. It is also requested that you grant acceptance of the April 15, 1977 submittal date for the Inservice Inspection Program waiver requests and the October 1977 Inservice Inspection Program development date.
Very truly yours, J.T. Rodgers Asst. Vice President ECS/hw 3/19 a

- Normally closed check valves that cannot be operated during normal plant operation (As per IWV-3520, paragraph B).
- The code requires that this category of valves be identified-but does not require testing of these valves.
However, our present program vill require that the positions of these valves be verified once every 3 months during normal operations.
