                Gentlemen:
                SUBJECT: NOTICE OF VIOLATION (NRC INSPECTION REPORT No. 50-255/85-09)
                This refers to the special team inspection conducted by the NRC April 29 -
              - May 3,1985 of activities authorized by Operating License No. DPR-40 for the
                Fort Calhoun Station. The results of this inspection were previously sent to you
                by our letter of July 26, 1985. The inspection team identified six deficiencies
                classified as Potential Enforcement / Unresolved Items. We have determined from a
                further. review of these matters during a followup inspection by Region IV on-
                November 18-22, 1985 and meetings with your staff in the Region IV office on
                December 12-13, 1985 that five of the six Potential Enforcement / Unresolved Items
                were in violation of NRC requirements.    Since you waived your opportunity to
                hold an enforcement conference, one was not conducted.
                We consider Violation A in the enclosed Notice of Violation involving
                qualification of Conax Electrical Penetration Assemblies within the scope of
                10 CFR 50.49 requirements to be of significant concern. The modification devised
                by Omaha Public Power District (OPPD), after it was discovered that Teflon seals
                and conductor insulation in the penetration assemblies had failed qualification
                tests, consisted of potting the junction between the penetration assembly bodies
                and the related pigtail wires using room temperature vulcanizing (RTV) silicone
                rubber. Since you failed to test the penetration assemblies after making
                the modification, the ability of the RTV material to remain bonded through
                the differential expansions and the severe environment of a LOCA was not
                assured in this application. Thus, the penetration units still were not
                appropriately qualified. The extent 6f the deficiency is very broad in
                that the electrical circuits for all equipment located inside containment
'
                must pass through the penetration assemblies; power, control, and
                instrumentation wiring for both safety-related and non-safety-related equipment
'
                inside containment potentially could be affected.

                    In accordance with the " General Statement of Policy and Procedure for NRC
                    Enforcement Actions," 10 CFR Part 2 Appendix C (1985), Violation A described
                    in the enclosed Notice has been classified at a Severity Level III. The other
                    violations have each been classified at a Severity Level IV. Normally, a civil
!                    penalty is considered for a Severity Level III violation. However, after
:                    consultation with the Director, Office of Inspection and Enforcement, I have
i                  decided that a civil penalty will not be proposed in this case because the
                    violations were identified prior to November 30, 1983 and this item is of the
                    type for which an extension prior to November 30, 1985 could have been granted
                    if requested before the deadline. We also recognize that following identification
                    of this problem by the NRC, you provided complete and timely reports concerning
                    your evaluation and corrective actions and you took extensive corrective action,
                    including the replacement of all penetration assemblies with units that have
                    been appropriately qualified.
                    You are required to respond to this letter and you should follow the instructions
                    specified in the enclosed Notice when preparing your response. Our inspection
I
                    activities and your letter dated January 11, 1986 indicate that corrective
                    actions are now complete. However, further response from you is necessary to
                    document the actions you have taken on each specific iten and to address any
                    other actions you plan to take to ensure that other deficiencies similar to those
                    noted do not adversely affect any other safety-related equipment. Where you have
                    already responded in writing to these findings (such as your letter of October 11,
                    1985), you do not need to repeat that information but need only reference
                    earlier communications and add additional detail not already contained therein.
                    After reviewing your response to this Notice, including your proposed corrective
                    actions, the NRC will determine whether further NRC enforcement action is
                    necessary to ensure compliance with NRC regulatory requirements.
                    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 enclosure                                      1
                                                                                                                                          '
                    will be placed in the NRC Public Document Room.

                    The responses directed by this letter and the enclosed Notice are not subject
'
                    to the clearance procedures of the Office of Management and Budget as required
                    by the Paperwork Reduction Act of 1980, PL 96-511.
                                                                                Sincerely,
