Open Items Nos. 50-295/89024-01 and 50-304/89022-01; w1ich were the result of a routine inspection conducted by Messrs. A. G. Januska and M. C, Schumacher of the
.USNRC Region III from July 31 to August 4, 1989.
1 The Open Items were a result of the need for analysis to be performed by off-site vendors.
