ENFORCEMENT CONFERENCE SUMMARY
(NRC INSPECTION REPORT NO. 50-261/91-20)
This letter refers to the Enforcement Conference held at our request on
November 6, 1991.
This meeting concerned activities authorized for your H. B.
Robinson facility. The issues discussed at this conference were design control
measures related to the loss of coolant analyses and overtemperature delta
temperature modifications. A list of attendees and a copy of your handout are
enclosed.
We are continuing our review of these issues to determine the
appropriate enforcement action.
In accordance with Section 2.790 of the NRC's "Rules of Practice," Part 2,
Title 10,
Code of Federal
Regulations,
a copy of this letter and its
enclosures will be placed in the NRC Public Document Room.
Should you have any questions concerning this matter, please contact us.
Sincerely,

CONCLUSIONS
SUMMARY
DISCOVERY WAS PRODUCT OF PHILOSOPHY AND
MANAGEMENT PRINCIPLES THAT SERVE AS CORNERSTONE
OF ENGINEERING AND DESIGN ACCOUNTABILITIES.
THAT IS:
SELF-ASSESSMENT
-
SELF-DISCLOSURE
-
OPERATIONAL SKEPTICISM
CONSERVATIVE DECISIONS
-
PROTECT THE CORE
-
"WALK THE TALK"

CONCLUSIONS
THERE ARE NOT SIGNIFICANT DEFICIENCIES IN
H. B. ROBINSON'S DESIGN CONTROL PROCESS
DESIGN CONTROL RESULTED IN IDENTIFICATION OF
ERROR
ACTIONS WERE PROACTIVE, CONSERVATIVE, AND
COMPREHENSIVE TO ASSURE:
MINIMAL SAFETY SIGNIFICANCE
DESIGN BASIS FOR H. B. ROBINSON IS SOUND TODAY
EFFECTIVE INTER/INTRA-DEPARTMENTAL
COMMUNICATIONS
CAPABLE AND IMPROVING ENGINEERING
WELL STRUCTURED AND DISCIPLINED ENGINEERING
PROCESS
ESCALATED ENFORCEMENT IS NOT WARRANTED FOR THE
