Subject:
SEP Topic XV-16 R.E.
Ginna Nuclear Power Plant Docket No. 50-244
Dear Mr. Crutchfield:
This letter is in response to a letter from Dennis Ziemann dated March 11, 1980.
Mr. Ziemann requested that we provide additional information to aid the Staff in its continuing review of SEP Topic XV-16, "Radiological Consequences of Small Lines Carrying Primary Coolant Outside Containment".
The requested information is presented in attached Table 1.
All of'he drawings referenced on the table except 33013-533 were sent with a letter dated September 12, 1978. to Mr. Ziemann.
Seven copies of drawing 33013-533, Revision 0 are enclosed with this letter.
Sincerely yours, L. D. White, Jr.
