DEC 141972 William P.
Cammill, Chief.. Site Analysis Branch, L SEISMICALLY INDUCED FLOOD POTENTIAL - RANFORD RESERYATION -
TELEPHONE CONFERENCE WITE WPPSS DECEMBER 13, 1972 On December 13, 1972. L.
Humpherys, D.
Renberger, and R. Chitwood of WPPSS called me to discuss the design criteria for Hanford 1 re seismically-indet.ed flood potential from failure of Grand Coulee Dam.
The WPPSS people explained their geologic investigation'of the Grand Coulee Dam vicinity from which they were unable to conclude whether an' active fault existed in the vicinity of the Dam.
They asked'whether the flood design basis for Hanford 2 would be adequate for Hanford 1.
I indicated that without asuurance that an active fault did not exist in the vicinity of Grand Coulee we could not conclude that the design basis for Hanford 2 or FFTF was adequate.
Mr. Humpherys asked whether the Corps of Engineers nuclear weapons effect study of Grand Coulee, which indicated an outflow fron the dam of'about 20 million efs, would be adequate for a design basis at Hanford 1.
I said I could not con-clude so out-of-hand, but would have to study this case further.
The WPPSS peop le also indicated that che Corps of Engineers has indicated the possibility of a flood-plain constriction downstream of Grand Coulee Dam that might limit river flows in the event of failure of Grand Coulee Dam.
I discussed with WPPSS representatives the content of the proposed flood design basis safety guide, particularly that se c tion wh'ich indicates that only l
I those facilities necessary for shutdown and maintenance of shutdown need he protected for the more severe flood events, providing sufficient warning time is available to shut the plant down.
