n APPENDIX A NOTICE OF VIOLATI0ft Tennessee Valley Authority Docket Hos. 50-327 & 50-328 Sequoyah 1 and 2 License Nos. DPR-77 & DPR-79 As a result of the inspection conducted on April 6 - fiay 5,1982, and in accor-dance with the NRC Enforcement Policy, 47 FR 9987 (liarch 9,1982), the following violations were identified.

A. Technical Specification 6.8.1.a requires that written procedures be imple-mented covering activities referenced in Appendix "A" of Regulatory Guide 1.33, Revision 2, February 1978 including operation of the Control Rod Drive System.

Contrary to the above, the licensee did not implement System Operating Instruction 501-85.01 " Control Rod Drive and Rod Position Indication System" in that on April 21,1982 a Unit 1 operator attempted to parallel the #1 Rod Drive Motor Generator (RDMG) with the operating #2 RDriG by closing the output breaker with the manual control switch. This action which is contrary to the instructions in 501-85.01 caused both RDl1G output breakers to trip and resulted in an unnecessary reactor trip.

This is a Severity Level IV Violation (Supplement I.D.2.). This violation applies to Unit 1 only.

B. Technical Specification 3.7.8 requires that two independent Auxiliary Building Gas Treatment (ABGTS) filter trains shall be operable when either unit is in mode 1, 2, 3 or 4.

Contrary to the above, two trains of ABGTS were not operable with Unit 1 in Mode 2 and Unit 2 in mode 1 in that on April 26, 1982 the inspector found both elevation 690 auxiliary building doors propped open. At least one door of each entry portal to the auxiliary building must remain shut in order to maintain the integrity of the Auxiliary Building Secondary Containment Enclosure and ensure that the ABGTS can maintain the required negative pressure in the auxiliary building during an accident.

This is a Severity Level IV Violation (Supplement I.D.2.). This violation applies to both Units.

Pursuant to the provisions of 10 CFR 2.201, you are hereby required to submit to this office within thirty days of the date of this Notice, a written statement or explanation in reply, including: (1) admission or denial of the alleged viola-tions; (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 8207150573 820630 DR ADOCK 05000
