SUBJECT:
REVIEW AND ACCEPTANCE OF TOPICAL REPORT EDR-1, EDERER"5 NUCLEAR )
SAFETY RELATED extra-Safety.A_nd _M_onitoring (X-SAM) CRANES, REVISION 1 1
The Nuclear Regulatory Commission staff has completed its review of the Generic 4 Licensing Topical Report EDR-1., "Ederer's Nuclear Safety Related eX_tra-Safety ' ,
And Monitoring (X-SAM) Cranes, Revision 1. The topical report describes the
" design and testing of the " single-failure proof" features which are included in Ederer's X-SAM cranes intended for handling spent fuel casks and other safety-related loads in a nuclear pl&nt. A summary of our evaluation of the topical teport is enclosed.
As a result of o'ur review, we have concluded that the design features described
/.@ in the topical report are acceptable for assuring that a single failure will
not result in the loss of capability to safely retain a critical load. These feataresiare limited to the hoisting system and brake system for trolley and brice.

Therefore, the Topical Report EDR-1, Ederer's Nuclear Safety-Related (X-SAM) Cranes, Revision 1, may be referenced as accepted for use in crane systems for nuclear power plants. Both the proprietary and non-proprietary versions of the topical report must be referenced in future license applications.
The topical report and our evaluation describe the degree of conformance of the Ederer X-SAM crane system with each of the regulatory guide positions given in Regulatory Guide 1.104, " Overhead Crane Handling Systems for Nuclear Poier Plants." Our safety evaluation notes that the applicant should include the information identified in Appendices B and C of the topical report in the Safety Analysis Report. Furthemore, in the alteration or conversion of an existing crane to provide features found acceptable in the topical report, the accepta-bility of unreplaced structures and components must be demonstrated.
We do not intend to repeat our review of the safety features described in the topical report and found acceptable in Enclosure 1. Our acceptance applies only to the use of-features described in the topical report and does not con-stitute apceptance of the total overhead crane handling system or the require-ments (e.g., limits on loads or load movement) which niay be necessary to assure
.C.6) / the safe hpplication of the crane system within the nuclear power plant.
