SOURCE OF REQUIREutNT vlotATED Design Standards DS-E8.1.1 & DS-E8.1.2 ,_ bW' DESCRIPTION OF CONDITION The 15B501 series was issued by ECi P0282 in 11/79 to provide the plant a plant specific

     'N'     fuse substitution list.                             Subsequently, Design Standard DS-E8.1.1 was issued 5/80 based cn D     the BTNP plant specific document with minor differences. The 15B501 series was not revisei N      to reflect these differences nor was an exception filed. This is also the case for all subsequent                 revisions to DS-E8.1.1 and all revisions to (S-ES.I.2 which address additional types of fuses. Revision 4 of DS-E8.1.1 and revision D of DS-E8.1.2 essentially disallow most fuse substitutions and only with design analysis and approval. The BTNP plant specif: e document (15B501 series) has not been revised to reflect these limitations or meet other requirements of later revisions of the Design Standards.
