(Respcase to IE Bulletin -17, Revision 1 for Unit 1)
Letter dated January 15, 1980 to Mr. J. G. Keppler from Mr. R. P. Crouse (A followup to the November 28, 1979 response on IE Bulletin 79-17, Revision 1 for Unit 1)
The NRC forwarded IE Bulletin 79-13 titled, " Cracking in Feedwater System Piping" and IE Bulletin 79-17 titled, " Pipe Cracks in Stagnant Borated Water Systems", for specific action to be taken.
1.
In the response to IE Bulletin 79-13, the inspector reviewed radio-graphs of the seven pipe to nozzle and elbow welds out to the first support on the auxiliary feedwater system line on steam generatot j
1-1.
The interpretation could not be completed on several radio-i graphs, primarily because of the density being under minimum re-quirements on the area of interest and the density of the radio-graphs through the lightest area of interest varied by more than

.
minus 15 percent from the density through the penetrameter. The licensee informed the inspector that the welds would be re-radio-graphed in accordance with ASME Section XI, 1974 Edition, Summer 1975 Addenda.
B&W is to perform the radiography in accordance with B&W procedure Radiographic Examination of Welds and Base Materials, 151-300, Revision 11, February 7, 1980.
The main feedwater nozzle connections are bolted on the B&W Unit and the auxiliary feedwater injection system is not used; there-fore, the feedwater level within the steam generator can be main-tained essentially constant with no intermittent cold auxiliary feedwater injection. Since the auxiliary feedwater injection system is not used, no radiography is required including the aforementioned pipe to nozzle elbow welds, reference IE Bulletin No. 79-13, Revision 2, paragraph 2.b.
Visual inspection of all feedwater system piping supports and snubbers in containment verifying operability and conformance to design is still to be performed.
IE Bulletin No. 75-13 may be completed in the next outage April 1980. The TECo " Visual In-spection of Snubbers, ST5044.01" is to be used. This is an unre-solved item.
(346/80-03-01).

Functional or Program Areas Inspected 1.
Spent Fuel Storage Modification A letter was sent December 1977, to Mr. E. G. Case, Acting Director, NRC, Washington, D.C. requesting to modify the spent fuel storage facilities from 260 assembly capacity to 735. The letter stated that a modification was necessary before the first refueling (which is anticipated to be April 10, 1980) in order to replace the racks with no spent fuel in the pool and to maintain the ability to dis-charge spent fuel while maintaining full core (177 fuel assemblies)
off-load capability.
August 1,1979, Mr. R. W. Reid, Chief, Operating Reactors Branch No.
4, Division of Operating Reactors, authorized an increase in spent fuel outage capability from 260 to a maximum of 735 fuel assemblies in the spent fuel pool through the use of high capacity spent fuel racks.
2.
Metal Products Corp. (MPC) fabricated the high density spent fuel racks in accordance with TECo Specification C63 and appears to satisfy PO No. Q29045C, dated December 19, 1979, to Nuclear Energy Services (NES) from TECo and the NES QA Program for Design and Fabri.ation of Spent Fuel Storage Racks No. 81A0502, Revision 2, September 11, 1978.
