ENCLOSURE BELLEFONTE NUCLEAR PLANT UNITS 1 AND 2 RESPONSE TO SEVERITY LEVEL V VIOLATION 50-438,50-439/82-18-01 FAILURE TO FOLLOW PROCEDURE FOR HANGER INSPECTIONS Description of Deficiency 10 CFR 50, Appendix B, Criterion V, as implemented by Bellefonte FSAR section 17, paragraph 17.1 A.5, requires in part that activities affecting quality be accomplished in accordance with instructions, procedures, or drawings. Bellefonte QCP 6.17, R3, states the procedure and acceptance criteria for inspection of seismic supports.

Contrary to the above, between June 8-11, 1982, activities affecting quality were not being accomplished in accordance with documented procedures in that a reinspection of seven completed and inspected seismic supports revealed three supports with deviations from the documented requirements.

Admission or Denial of the Alleged Violation TVA admits the violation occurred as stated.

Reasons for the Violation Several factors have contributed to the root cause of the subject violation as stated below:

A. Improper installations of items / components and/or unauthorized rework or inadvertent damage to items / components after QC inspections were performed.

B. Improper QC inspections of items / components because of:

1. Lack of proper training for QC inspectors.

2. Insufficient "in-house" auditing of QC inspections.

Corrective Action Taken and Results Achieved Quality Control Investigation Reports (QCIR) have been initiated for each item found to be discrepant. They will be processed and the items corrected per applicable procedures and work schedules.

Page 2 Steps Taken to Avoid Further Violations Actions which have or will be taken are noted below.

A. A comprehensive program is being formulated to provide more intensive i training for QC inspectors. This program will include classroom and i field training on a scheduled basis for all applicable personnel.

Periodic testing will be required of each individual to retain certification io applicable procedures.

., B. The Hanger Engineering Unit (HEU) internal audit inspection program has been enhanced by providing personnel with more experience regarding inspection of hangers. The program is showing evidence of improvement based on the latest finding of the HEU audit team.

C. The engineering organization will coordinate more closely with craft personnel in the field to resolve discrepant items before QC inspections. This includes more direction to the craftsmen to avoid unauthorized work and damage to items / components previously installed and inspected in the field.

)

D. A third reinspection is being performed on those hangers previously inspected and accepted by the HEU internal audit program over the last six months. Results of this inspection are to be evaluated jointly between TVA's Division of Construction.and Division of Enfineering l

' Design to determine if some of the existing QC inspection criteria may be reclassified as nondocumented engineering inspections. The engineering inspection would be performed on certain noncritical aspects which do not compromise the structural integrity or safety significance of the hangers.

E. A memorandum has been issued by the steam fitter superintendent to steam fitter personnel emphasizing the total commitment to the QA/QC program. This memorandum includes instruction which prohibits unauthorized rework to hangers.

Date of Full Compliance The corrective actions noted in B, C, and E are in effect. The other corrective actions will be in effect by December 29, 1982.
