8002280665 IE Circular No. 80-10 April 29, 1980 Page 1 of 1 FAILURE TO MAINTAIN ENVIRONMENTAL QUALIFICATION OF EQUIPMENT Description of Circumstances:
Carolina Power and Light recently reported that the wrong class of insulating material had been used at their H. B. Robinson Nuclear Plant when the motor leads of a containment fan cooler were reconnected.
The motor leads had been disconnected during the refueling outage to supply power to welding equipment.
When the motor leads were reconnected, the wrong class of insulating material degraded the environmental qualification of the containment fan cooler motor.
A similar event, reported by Duquesne Light Company, occurred when a containment fan cooler motor was not installed with the.proper cabl~ insulation.
The NRC has previously issued IE Circular 78-08 and IE.Bulletins 79-01 and 79-018 concerning environmental qualification of Class IE equipment. These Bulletins primarily address the environmental qualification of equipment as purchased and installed; however, the above events emphasize the importance of properly installing and maintaining environmentally qualified equipment.
Recommended Acti-0n for Licensee Consideration:
All holders of operating licenses or construction permits should recognize the potential for degradation of environmentally qualified equipment due to improper maintenance or improper use.
It is recommended that licensees review current maintenance procedures and administr.ative policies to ensure the following:
- 1.
Adequate administrative controls exist to ensure that equipment which is environmentally qualified is identified prior to maintenance.
- 2.
Maintenance procedures provide necessary instructions and precautions to ensure that the environmental qualification of equipment is not degraded when maintenance is completed.
- 3.
Maintenance personnel are adequately trained on environmental qualification requirements and the potential for equipment degradation from improper maintenance.
No written response to this Circu1ar is required.
If you require additional information regarding this matter, contact the Director of the appropriate NRC Regional Office.
