ENCLOSURE
NOTICE OF VIOLATON Tennessee Valley Authority Browns Ferry 1, 2, and
Docket Nos.50-259, 260 and 296 License Nos.
DPR-33, 52 and
The following violations were identified during an inspection conducted on August 31 - September 30, 1985.
The Severity Levels were assigned in accordance with the NRC Enforcement Policy (10 CFR Part 2, Appendix C).
1.
CFR 50, Appendix 8, Criterion V requires that activities affecting quality shall be prescribed by documented instructions, procedures, or drawings of a
type appropriate to the circumstances and shall be accomplished in accordance with these instructions, procedures or drawings.
This requirement was not met for the following four examples:
a.
Contrary to the above, the licensee failed to maintain the Reactor Protection System (RPS) Circuitry as prescribed in drawing 791E247-2A Rev.
22.
On August 29, 1985, a-.terminal block jumper link which was.
required to be attached to terminals number 79 and 80 of terminal board CC on the Unit
RPS panel 9-17 was not attached with terminal screws.
This jumper link is in the RPS Scram Valve Test Timing Marker Circuitry.
Additionally the fire proof metallic enclosures which house fuses F12, F13, F16 and F17 in panel 9-17 had lost their fire proof integrity due to the enclosure cover not being properly secured, leaving a
one-half inch opening into the enclosures.
The wires required to be attached to terminal 3 of fuses F13 and F17 were not installed on the Unit 1 panel 9-17.
The one-half inch flex conduit from the fire proof metallic enclosures housing fuses F12, F13, F16 and F17 in panel 9-17 of Unit 1 was not terminated as close as possible to the terminal board but was terminated about one inch from the enclosure.
b.
Contrary to the above, the licensee failed to adhere to Standard Practice 17.9, Surveillance Requirements Program, on August 27, 1985 and August 28, 1985.
Standard Practice 17,.9 requires that Surveillance Instruction test data be maintained as quality assurance records with a
lifetime retention period.

DPR-33, 52 and
C.
B Diesel Generator at 1430 on August 27, 1985, and again at 0105 on August 28, 1985 could be found.
Contrary to the above, the licensee failed to adhere to Standard Practice 7.6, Maintenance Request and Tracking, on April 26, 1985.
Standard Practice 7.6 requires that Critical Structures Systems and Components (CSSC)
and Safety Related Maintenance Requests (MRs) shall refer to Plant Operations Review Committee (PORC) reviewed instructions unless the maintenance to be performed involves skills normally possessed by qualified maintenance personnel and does not require step-by-step details for the actual performance of the work. If a PORC reviewed instruction is required and has not been written, an MR may be written and sent to PORC for review and the plant superintendent's approval.
On April 26, 1985, Maintenance Request A-170596 was performed on the safety-related TD2C relay with detailed step-by-step work instructions on the MR which had not been PORC reviewed and approved.
The work instructions involved operability verification of RHRSW pump automatic start logic circuitry which is normally verified during performance of approved surveillance instructions and is beyond the skills of qualified electrical maintenance personnel.
d.
Contrary to the above, plant operating instructions did not address operation of the containment purge system charcoal bed heaters.
On..
September 12, 1985, the charcoal bed heaters were found with the handswitch in the OFF position for all three units for no apparent reason.
The heaters remove any moisture accumulation which might reduce the required iodide removal capability of the charcoal bed as discussed in Technical Specification 3.7.F.2.6.
This is a Severity Level IV violation (Supplement I) and js applicable to all three units.
2.
CFR 50, Appendix B, Criterion VI requires that measures be established to control the issuance of documents, such as instructions, procedures and drawings, including changes thereto, which prescribe all activities affecting quality.
These measures shall assure that documents, including changes, are distributed to and used at the location where the prescribed activity is performed.
Contrary to the above, the licensee failed to issue and distribute as-constructed drawings documenting changes to the Vacuum Breaking System associated with the Condenser Circulating Water System which occurred as a
result of work performed in July 1978, under work package number 5895 (Unit 1),
5991 (Unit 2),
and 7653 (Unit 3) for ECN Number L 2002.

A.
This is a Severity Level IV. violation (Supplement I) and is applicable to all three unit Tennessee Valley Authority Browns Ferry 1, 2, and
Docket Nos. 50-259, 260 and 296 License Nos.
DPR-33, 52 and
3.
CFR 50, Appendix B, Criterion XVI requires that measures shall be established to assure that conditions adverse to quality such 'as failures, malfunctions and deficiencies are promptly identified and corrected.
In the case of significant conditions adverse to quality, the measures shall assure that the cause of the condition is determined and corrective action taken to preclude repetition.
Identification of the condition, cause of the condition, and corrective action shall be documented and reported to appropriate levels of management.
The licensee failed to determine the cause and take corrective action to preclude repetition of a significant condition adverse to quality and further failed to document and report the cause and corrective action to appropriate levels of management.
On August 27, 1985, a significant condition adverse to quality occurred when the Units
and 2, B Diesel Generator failed to start when given an automatic start signal during the performance of a routine monthly surveillance test (SI 4.9.A. 1.A, Diesel Generator Monthly Test).
Although various maintenance activities'ere performed over the next few days and the diesel subsequently passed the monthly surveillance on August 29, 1985, the cause of the original failure to start was not determined, documented or reported to management.
Since the cause was not determined, no action was taken to preclude repetition of the condition adverse to quality.
This is a Severity Level IV violation (Supplement I) and is applicable to all three units.
Pursuant to
CFR 2.201, you are required to submit to this office within 30 days of the date of this Notice, a written statement or explanation in reply, including:
( 1) admission or denial of the alleged violations; (2) the reasons for the violations if admitted; (3) the corrective steps which have been taken and the results achieved; (4) corrective steps which will be taken to avoid further violations; and (5) the date when full compliance will be achieved.
Security or safeguards information should be submitted as an enclosure to facilitate withholding it from public disclosure as required by
CFR 2.790(d)
or 10 CFR 73.21.
