Dear Mr. Parr:
I In your April 17 and 2',
1975 letters (Refeyences 1 and 2) to us, you re-quested that we provide further information on the adequacy of the Mark II Containment on our WPPSS Nuclear Project No.
2 with respect to recently identified hydrodynamic loads.
The purpose of this letter is to:
o Provide information relative to the status of the Mark II Supporting Program.
m
Mr. Olan D. Parr Page 2
November 10, 1975 G02-75-310 o
Reference recent generic documents containing information felt applic-able in determining Mark II containment dynamic loads on the WPPSS Nuclear Project No.
2 docket..
o Provide table of load factors for concrete structures.
lt In Attachment "A" of our June 5, 1975 letter (Reference 3), we provided to you our schedule for conducting an assessment of our containment struc-tures.
Item 1 of Attachment "A" was submitted to you on July 25, 1975.
Item 2 and a portion of Item 3 of Attachment "A" are covered by the Mark II Containment Dynamic Forcing Function Information Report (DFFR)
NEDO-21061 and NEDE-21061P.
The DFFR was transmitted via GE letter from I.F. Stuart to R. Boyd dated October 24, 1975, and contains phenomena descriptions which will be used to evaluate the Mark II containment for the WPPSS Nuclear Project, No. 2.
Item 2 was submitted later than expected due to additional technical efforts required to complete the DFFR and the inclu-sion of phenomenological information on Item 3.
As a consequence, Item 4, our plant unique report, is now expected to be submitted in the December 1975 to January 1976 time period.
We also expect to complete and include the remaining answers to Item 3 in that plant unique report.
On June 30, 1975 the Mark II Containment Owners presented to the NRC an out-line and schedule for the Mark II Supporting Program.
This Supporting Pro-
- gram, Item 5, was submitted to you on September 16, 1975 (Reference 5).
The status of this Program is. as follows.
Under LOCA Related Activities, Item A.3 (Impact Tests on Pool Internal Structures) and Item A.4 (gualifi-cation of Impact Model) are covered by recently submitted documents NEDE-13426-P Class III, and NEDC-20989-2P (Vol. 2) respectively.
The following documents have been submitted to address Item 8.2 (Relief Valve Pipe Clear-ing for Ramshead) under the Safety/Relief Valve Related Activities:
1)
For modeling - NEDO-20942 and NEDE-20942P.
2)
For test comparisons
- NEDO-21062 and NEDE-21062P.
The attached table of load factors will be used to evaluate the WPPSS Nuclear Project No. '2 concrete structures inside containment.
This table identifies the numerical values and is complementary to Table 5.2.1 in the DFFR.
As you know, our WPPSS Nuclear Project No. '2 containment is a free-standing steel structure'overned by Division 1
(NE-3000) of Section III of the ASME Code.

Mr. Olan D. Parr Page 3
November 10, 1975 G02-75-310's a member of the Mar k II Owners
- Group, we will be closely following the progress of the Supporting Program and keep you advised of its progress.
Any reports, data or analyses which become available during'the Supporting Program, will be forwarded to the NRC through appropriate channels.
