Dear Sir:
Three Mile Island Nuclear Station, Unit 2 (TMI-2)
Operating License No. DPR-73 Docket No. 50-320 Polar Crane Ioad Test SER Attached for your review and cmment is Addonrhrn I to the Polar Crane Ioad Test Safety Evaluation Report (SER).
The purpose of this addendum is to update the subject SER to incorporate changes which have taken place as a consequence of responses to NRC and other coments regarding the Ioad Test Procedure and the Operating Procedure.
A discussion of the changes follows.
(The numbering used below corresponds with that used in the SER.)
Section 2.4 Disassembly of Test Inad. The load test frame may be stored along with the missile shields on top of the "B" D-Ring. The safety aspects of this activity are totally enveloped by the evaluation done for the dropping of a missile shield.
Figure 2.3-1 Path of Test Ioad Assembly. A 45 rotation evolution has been added to the test procedure during the m vement of the full test load to verify hook rotation.
Figures 2.4-2 and 2.4-3 load Path of Reactor Missile Shield Blocks to Storage Iocation after Completion of load Test. The load path has been modified such that the shield blocks are moved in a counter-clockwise direction rather than the clockwise direction as presently shown. The safe load path has been evaluated and expanded slightly in the vicinity of the enclosed stairwell to accomodate the revised load path of the reactor missile shields. Please refer to drawings 2-P09-MH04, Revision 0, and 2-P09-MH02, Revision 1, attached.
