Dear Mr. Norelius:

In response to your letter of November 4,1985, relative to activities associated with Metalweld. Inc., The Cleveland Electric Illuminating Company (CEI) has investigated each of the five concerns noted. We have analyzed each concern, performed necessary inspections and conducted appropriate investigations to determine the validity and significance of the conditions. Additionally, appropriate actions have been taken to address both the specific concerns and root causes. Our review noted that Concerns 2, 3 and 4 were discovered during. routine inspections and were documented and tracked on Nonconformance Reports prior to our receipt of your concern.

Below is a summary of the results of our investigations and inspections as well as the action taken to date to resolve each concern.

Investigative Results for Concern #1 Background checks and inspections of applicable work areas failed to substantiate the improper use of controlled substances at the Perry Nuclear Power ?lant (PNPP). To further substantiate that work was performed in accordance with the high quality standards of PNPP, a reinspection of 28 selected areas was performed in which the identified craft and inspection personnel had worked common areas. No workmanship deficiencies were noted. This inspection coupled with a review of the contractor's quality program indicated that the program was effective in ensuring quality workmanship at every stage of the process.
