SUBJECT: NRC INTEGRATED INSPECTION REPORT 50 327/97 06 AND 50-328/97 06

AND NOTICE OF VIOLATION

Dear Mr. Kingsley:

This refers to the inspection conducted on May 25 through July 5, 1997 at the

Sequoyah facility. The enclosed report presents the results of this

inspection.

During the inspection period, your conduct of activities at the Sequoyah

facility were generally characterized by adequate operations, with good

control of power changes and problem identification and negative observations ,

in procedure compliance and o>erator training; adequate maintenance, with

positive observations in trou)leshooting and pre job briefings and negative

observations in procedure compliance and numerous equipment failures: adequate

engineering, including good quality of modifications and negative observations

in the Generic Letter (GL) 89-10 program, ASME Section XI program, and

corrective actions for deficient relief valve settings; and good plant

support, with positive observations in radioactive shipping, waste storage,

dose control, and water chemistry and a negative finding for failure to

maintain proper air pressure in the auxiliary building. Nuclear Assurance

audits were strong, intrusively focused and continued to identify significant

areas needing improvement. A significant finding by Nuclear Assurance

involved an observation that control room personnel generally reacted to

abnormal conditions in a routine manner. This is consistent with ongoing NRC

concerns that material condition deficiencies are numerous and often challenge

operators. The NRC is concerned with the findings identified during the

Corrective Action Program inspection. While it was noted tnat management

involvement in the Corrective Action Program has improved, weaknesses

identified during the ins)ection indicated that the improvements in /

implementing the process lave leveled off and continued attention is I

warranted.

Based on the results of this inspection, the NRC has determined that

violations of NRC requirements occurred. The violations are cited in the

enclosed Notice of Violation (Notice) and the circumstances surrounding them

l are described in detail in the subject inspection report. A violation was

! identified for inadequate corrective actions associated with improper safety

injection system relief valve settings. Following initial NRC concerns with

the interpretation of ASME code requirements and subsecuent corporate review

of the relief valve setpoint issue, the licensee failec to properly

' interpret and implement ASME/ ANSI code requirements. A second violation was

identified for failing to promptly identify that a negative pressure was not i

, being maintained in the auxiliary building as required by the UFSAR.  ;

. You are required to respond to this letter and should follow the instructions 1

l specified in the enclosed Notice when preparing your response. The NRC will

use your response, in part, to determine whether further enforcement action is ,

necessary to ensure compliance with regulatory requirements. i
