Submittal of Revision 1 to the ABWR Design Control Document

References:

(1) R.W. Borchardt to Mr. Joseph Quirk, dated December 8,1994. (2) J.F. Quirk te Mr. Dennis Crutchfield, Submittal of Final ABWR Design Control Document, MFN No.134-94, dated October 28,1994. Enclosed is one (1) copy of the replacement pages to the subject document for the Docket Control Desk and one (1) copy for the Public Document Room. Further, in accordance with direction of NRR project staff, General Electric Nuclear Energy (GE-NE) is prmiding thirteen (13) copies of the replacement pages to the NRR recipients listed on Attachment 1. This is being done to accelerate the distribution process and ensure timely staff receipt. As requested by the Reference 1, this revision of the DCD is accompanied by a list of the currently effective pages. This list is provided as Attachment 2. Reference 1 also requested that tables of Attachment 3 of Reference 2, that submitted DCD Revision 0 for review, be updated to reflect the staffs comments and any other changes, and be resubmitted as DCD Revision 1. In addition, Reference 2 requested that GE refer to information which was removed from the DCD because it represents detailed PRA information as " Industry Initiative" as opposed to "NRC DCD Guidance". This is also provided in this transmittal as. To better keep track of the updates and other changes pertaining to Resision 0 and Revision 1, inserts into the existing table as a result of i Revision 1 have been inserted as item numbers (L11 entry) with a lettered suffix (e.g.16a). When the entry is affected by both Revision 0 and Revision 1, a combined number and number with lettered sufIix (e.g.16/16a) is used. 9412280096 941222 [g PDR ADOCK 0520 1 g gr 10A0(GA t I

-p j., O E Finally, Reference 1 requested that GE reverify all building figures in Tier 1 Sections 2.15 and 3.2 for divisional, fire, flood, and radiological boundaries at the appropriate elevations.- This reverification has been completed and, where necessary, the Tier 1 figures have been realigned consistent with the Certified Design Material. Three Tier 1 figures were upgraded. All of the DCD Revision 1 replacement changes are identified in the Page Change Instructions (Attachment 4). Sincerelyg d Joseph F.

As part of the FOAKE. program, the systems cooled by the UHS were evaluated and it was determined that the federally mandated phase out of several commonly used refrigerants would require lowering the UHS temperature to 95 F (35 C). FOAKE also found that plate type heat exchangers would be much more suitable. Finally, itis prudent to allow the use of both screw-type and centrifugal-type chillers. 4 9-1 i m
