SUBJECT: NOTICE OF VIOLATION

(NRC INSPECTION REPORT NOS. 50-327/88-29 AND 50-328/88-29)

This refers to Nuclear Regulatory Commission (NRC) special announced team

inspection conducted by K. Jenison on June 20, 1988 through July 8, 1988. The

inspectior. included a review of the activities associated with the startup of

Sequoyah Unit 1 and the Sequoyah restart program matrix. At the conclusion of

the inspection, the findings were discussed with those members of your staff

identified in the enclosed inspection report.

The purpose of this inspection was to determine if adequate implementation of

corrective actions had occurred to support Unit I startup. These corrective

actions included TVA Nuclear Perfora nce Plan implementation and evaluation of

equivalent Unit 2 startup items on Unit 1. This determination was based on a

sample of the programma*.ic corr'ective actions that pertained to the containment

spray system. The results cf this inspection were used to evaluate the need

for additional NRC activity in specifically identified areas.

This inspection was composed of design and as-constructed aspects. Contact was

maintained between inspectors in each area such that their respective efforts

and inspection findings were coordinated. The design portions consisted of a

review of portions of the containment spray system design, design bases and

design requirements. The as-constructed portion consisted of an in plant

review in the mechanical, electrical, civil, structural, and instrumentation

and control disciplines in order to verify that the containment spray system as

currently constructed and installed is in accordance with the licensed design

basis, system design specifications, applicable drawings, system modifications

and temporary alterations. In addition, the operational capability of the

containment spray system was evaluated by reviewing the system operating

instructions and procedures, surveillance and testing requirements, corrective

and preventive maintenance activities, emergency operating instructions and

operator training. The inspection team evaluated, on a sampling basis,

portions of the TVA Nuclear Performance Plan functional corrective action

areas that were not addressed for Unit 1 in other inspections. The areas not

addressed for Unit 1 in other inspections were established by a review of

those NRC inspections conducted since the shutdown of Sequoyah Units 1 and 2

(August 1985).

The inspection findings indicate Uias certain activities appeared to violate

NRC requirements. The identified violations involved aissing system design

basis calculations, procedural noncompliances associated with electrical work,

structural walkdown discrepancies, and procedure inadequacies in the areas of

ASME Section XI testing and weld evaluations. The violatuns, references to

pertinent requirements, and elements to be included in you, response are

described in the enclosed Notice of Violation.

As discussed during the exit, several of the above violations have additional

corrective actions associated with them in order to ensure adequate resolution

of the issue. These additional corrective actions are as follows:

Violation 327, 328/88-29-01, Design Basis Calculation Discrepancies, has

associated with it additional corrective actions identified as Unresolved

Item 327,328/88-29-06a through s. Adequate corrective action for .his

violation should include resolution of these issues and a 100% Engineering

Assurance review of the results.

Violation 327,328/88-29-02, Structural Walkdown Discrepancies, Ms

associated with it additional issues which require unique, generic a,d

programmatic review. This review should also include a TVA Quality

Assurance review of the TVA pre-SSQE walkdown discrepancies and the

applicability of those discrepancies to other components.

Violation 327,328/88-29-03, Maintenance of Safety-Related Electrical

Equipment, has associated with it additional issues which require unique,

generic and programmatic review. This review should also include a TVA

Quality Assurance review of the TVA pre-SSQE walkdown discrepancies and

the applicability of those discrepancies to other components.

In addition to the above violations, several commitments were made during the

exit meeting on July 8, 1988, conducted for this inspection. These commitments

were:

To test the containment spray pump flow characteristics using a multiple

point test prior to the startup cf Unit 3.

To test the ESF pump valve logic performance as demonstrated in surveil-

  1. lance instruction 68 prior to the startup of Unit 1.

To complete licensee actions associated with establishing the 143 psid

pressure required to ensure 4750 gpm f rom the containment spray pumps

prior to the startup of Unit 1.

To determine actual containment spray anu RHR heat exchanger differential

pressure in order to resolve restart test functions72-003 and 72-018

prior to the startup of Unit 1.
