Petrone NEW ISSUE. The crane vendor Whiting Corporation reports that analysis of the main hoist on a crane similar to those in nuclear service has identified some over stressed conditions. This crane with the over stressed condition is a Whiting "Tiger Design" line crane with main hoist capacities from 75 tons to 240 tons. Some of these cranes were purchased in the 1960's and 1970's by nuclear utilities for use as reactor building cranes. Whiting stated that potentially affected cranes had been identified by serial number and that the owners of these cranes had been notified by letter. Whiting also stated that they are continuing to review records of other cranes to identify other potential candidates for notification. Whiting recommended that owners of suspect cranes should derate their main hoist capacity by 50 percent until an analysis of the crane can be completed. Completion of analysis for the first two cranes indicated that no modifications were needed. However, the adequacy of the remaining cranes can not be assured until an individual analysis is completed on each crane. The auxiliary hoist is not affected by this condition and can continue to be used without restriction. _ HEADQUARTERS MORNING REPORT PAGE 2 AUGUST 3, 1999 Licensee/Facility: Notification: Part 21 Database MR Number: H-99-0067 Westinghouse Date: 08/03/99 Subject: Part 21 - Safety-related W2 control switch would not work after installation Discussion: VENDOR: Westinghouse PT21 FILE NO: 99-29-0 DATE OF DOCUMENT: 05/27/99 ACCESSION NUMBER: SOURCE DOCUMENT: LETTER REVIEWER: REXB, D. Skeen NEW ISSUE. The Ginna licensee reports that a safety-related W2 control switch drawn from warehouse stock did not operate satisfactorily after being installed in the main control board as the control switch for a safety injection pump. The switch, which operated properly before being installed in the control board, would bind and fail to spring return to either the "after close" or "after trip" position after installation. The licensee returned it to the vendor, Westinghouse, for a failure mode assessment and 10 CFR Part 21 evaluation to determine if the switch was deficient at the time of manufacture. The evaluation is expected to be completed by October 1, 1999. _ REGION IV MORNING REPORT PAGE 3 AUGUST 3, 1999 Licensee/Facility: Notification: Agreement State Licensee MR Number: 4-99-0022 Trutec Date: 08/03/99 Baton Rouge,Louisiana Subject: CONTAMINATION EVENT AT LICENSEE'S FACILITY Discussion: The State of Louisiana notified Region IV by e-mail of a contamination event at a State of Louisiana licensee's site.
