8011040272 IN 81-08 UNITED STATES NUCLEAR REGULATORY COMMISSION OFFICE OF INSPECTION AND ENFORCEMENT March 20, 1981 IE INFORMATION NOTICE NO. 81-08:
REPETITIVE FAILURES OF LIMITORQUE OPERATOR SMB-4 MOTOR-TO-SHAFT KEY Description of Circumstances:
During normal surveillance testing of motor-operated valver at the Cooper Nuclear Station, it was discovered that the RHR "B" loop suppression pool cooling inboard throttle valve would not operate.
The valve did not operate because the key between the motor pinion gear and the motor shaft had failed.
The operator for the valve has been identified as being Limitorque model SMB-4.
Analysis of the failed key revealed that a standard type 1010 steel key had been installed instead of the required special type 4140 steel key.
Further review of the problem established that similar failures with motor-to-shaft keys had also taken place at the Pilgrim, Hatch, and Fitzpatrick nuclear power facilities.
Limitorque Company has performed an evaluation of the problem, and 'they have concluded that the problem is confined to operators having a torque rating in excess of 100 ft/lb.
The standard type 1010 steel possesses adequate strength to accommodate motor operators having a torqu eating that is less than 100 ft/lb.
Recommended Action for Holders of Operating Licenses and Construction Permits:
It is recommended that licensees having Limitorque Operator SMB-4 installed in their facilities verify that the special type 4140 steel keys have been used.
This can be easily accomplished by performing a hardness check of the notor-to-shaft keys during the next scheduled surveillance testing.
No written rbsponse to this information notice is required.
If you need additional information with regard to this subject, please contact the Director of the-appropriate NRC Regional Office.
