I.
Introduction This report addresses one concern (MAS-86-003) dealing with the adequacy of work being performed by construction concerning fuse identification workplans.
II.
Summary of Perceived Problem The concerned individual apparently felt no corrective action was being taken to resolve the fuse discrepancies noted between the design drawing and the installed configuration, as stated in workplan number 10512.
III. Evaluation Methodology A.
Discussed this concern with knowledgeable electrical maintenance personnel to determine the extent and specifics of the concern.
B.
Reviewed Workplan Number 10512 to determine the content of the plan and the areas covered.
IV.
Summary of Findings A.
The discussions with electrical maintenance personnel revealed this j
was a concern received under the "old" Employee Concern Program and a resolution had been discussed with the concerned individual.
This resolution would involve the Office of Engineering Design, the Inspector General, the Office of Construction Engineering, and an assistant unit operator. The design engineer will authorize changes in fuse size and manufacture type. Field Change Requests (FCRs) will be submitted to correct any drawing discrepancies.
Drawings will be marked up showing the correct configuration prior to workplan closure. This discussion also revealed that the concerned individual agreed that these corrective steps should resolve any problems that exist and would alsa satisfy his concerns.
B.
A review of Workplan Number 10512 revealed the work was to install nameplates or unique identifiers to all control fuses.
Identification will consist of a unique identifier, a manufacturer's code, and fuse rating.
