The following information was obtained from
Fisher Controls International via facsimile:
The equipment supplied included a 20 inch Fisher valve coupled to a Bettis actuator.
The purpose of this Fisher Information Notice (FIN 2009-03) is to alert Alabama Power that as of January 16, 2009, Fisher Controls International LLC became aware of the possibility of a situation which may affect the performance of the applicable equipment.
This notice applies only to the subject equipment supplied by Fisher Controls International LLC, identified above, that was provided to Alabama Power - Farley.
Fisher Controls has determined that the subject items were provided with parts that were not properly processed per active valve requirements specified by the Alabama Power Order.
Specifically, Fisher provided a coupler between the actuator drive lever and valve shaft that was not evaluated for all the critical characteristics deemed necessary for a commercial grade dedicated item per EPRI 5652 and Fisher Manufacturing Procedure FMP 2K27, 'Control of Commercial Grade Items to be Dedicated for Use in Nuclear Safety-Related Systems,' (Fisher Processing Level C).
We [Fisher Controls] are reviewing the situation and will pursue a corrective action investigation to prevent problems like this in the future.
Arrangements have been made with Alabama Power to retrofit a correctly processed part on the subject serial number.
This is a formal notification; Alabama Power was notified of this situation on January 16, 2008.
The
coupling provided to
Alabama Power did not meet the hardness requirements specified in the order. The coupler provided was annealed versus quench-hardened.
