Vice President, Engineering Limitorque Corporation 5114 Woodall Road Lynchburg, Virginia 24506
Dear Dr. Wilkinson:
SUBJECT:
NRC INSPECTION REPORT NO. 99900100/93-01 This refers to the inspection conducted by an inspection tearr, led by Mr. Jeffrey Jacobson of this office, on May 10-14, 1993. The inspection was conducted to review activities associated with Limitorque's supply of valve actuators t: the nuclear industry. At the conclusion of the inspection, the findings were discussed with those members of your staff identified in the enclosed report.
' Areas examined during the inspection are identified in the e.. closed inspection report (Enclosure 2). The inspection was conducted to evaluate Limitorque's:
manufacturing and engineering programs for safety-related items including design control, configuration control, and control of sub-vendors; corrective actions associated with 10 CFR Part 21 reports; commercial grade dedication activities; and corrective actions regarding unresolved items and concerns from previous inspection reports.
Based on the results of this inspection, two violations were identified. The first violation concerns Limitorque's failure to co71ete its evaluation and report the effects that relaxation of the actuatoi,nring pack may have on the i
operability of motor operated valves.
The second violation concerns Limitorque's failure to implement procedures as required by 10 CFR 21.21, to address certain substantive revisions of 10 CFR Part 21 that became effective Octoler 29, 1991. This failure to update internal procedures in a timely manner perpetuated Limitorque's misinterpretation of 10 CFR Part 21.21 reporting requirements and resulted in the failure to submit several completed evaluations' or interim reports to the NRC within 60 days. Corrective actions and preventive measures that were presented during the inspection, as documented in Enclosure ?, NRC Inspection Report 99900100/93-01, were satisfactory to close this violation, therefore, no response to this violation is required.
The results of the inspection indicate you have implemented significant improvements in your procedures for controlling commercial grade dedication, sampling, and material testing. However, your actions with respect to evaluating and resolving technical issues arising from valve operating experience and in reporting the resu?ts of these evaluations were found to be inadequate. Many of these issuas heve resulted from inadequacies in the
