Dear Mr. Storz:
This refers to the special safety inspection conducted by Mr. John H. Neisler
and others of this office on November 15-19, 1993. The inspection reviewed
,
,
the implementation of the Station Blackout (SB0) Rule, 10 CFR 50.63, at the
Davis-Besse Nuclear Power Station. At the conclusion of the inspection, the
findings were discussed with those members of your staff identified in the
enclosed report.
r
The team considered the SB0 rule to be adequately implemented. The material
condition of the plant and the SB0 equipment was good.
In addition, th'e
quality of the SB0 calculations and the abnormal and emergency operating
procedures for SB0 mitigation and recovery were good. .The team identified
some minor weaknesses in management control and design such as drawing
deficiencies, contractor control and questionable ground detection on the SB0
diesel generator DC system. Drawing deficiencies were also identified-during
a previous NRC inspection (reference NRC Inspection Report No. 50-346/93019).
Areas examined during the inspection are identified in the report.
Within
these areas, the inspection consisted of selective examinations of procedures
and representative records, interviews with personnel, and observation of
activities in progress..
>
No violations of NRC requirements were identified-during the course of this
inspection.
In accordance with 10 CFR 2.790 of the Commission's regulations,'a copy of
.
this letter and the enclosed inspection report will be placed in the NRC
Public Document Room.
,
We' will . gladly discuss any questions you have concerning this inspection.
Sincerely,
