REQUEST FOR ADDITIONAL INFORMATION CONSEQUENCES OF CRANE FAILURES THREE MILE ISLAND NUCLEAR STATION, UNIT NO. 1 DOCKET NO. 50-312 1.
2n your letters of February 14, 1976 and January 31, 1978, you define a transfer path for moving a fuel cask from the transporter to eleva-tion 348'-0".
In your letter of January 31, 1978 you also define a
" Unit 1 main hook travel area for loads over 15 tons." Among other uses, this travel area could be used for transporting a shipping cask
(
to the Receiving / Shipping Area.
Inasmuch as the cask transfer path was selected to assure the safety of that specific movement, provide the basis for the acceptability of moving casks or other loads weighing from 15 to 110 tons anywhere within the " Unit 1 main hook travel area for loads over 15 tons."
Inasmuch as no restrictions are placed on the limits of travel for 2.
loads weighing between 3000 pounds and 15 tons (except in the vicinity of the spent fuel pools), either:
(1) provide an analysis demonstrat-ing that dropping a 15 ton load at any point in the permissible area of travel (outside the " Unit 1 main hook travel area for loads over 15 tons") from the maximum permissible height would not damage redundant channels of safety related equipment or electrical cables, or (2) define a restricted area of travel and a restricted lift height and provide a similar analysis for these more restrictive conditions.
