The following is quoted selectively from t … The following is quoted selectively from the text of the original Part 21 notification received from Flowserve via fax:</br>On September 8, 2009, Flowserve Corporation was notified by Exelon-LaSalle Nuclear Power Station of a failure which occurred and was initially communicated via Flowserve Complaint Report #4914. </br>The Referenced Complaint Report describes an anomaly with a Size 3/4 Figure 848Y bolted bonnet valve at the LaSalle Nuclear Power Station. </br>The subject valve was in service at the time of disassembly. The disassembly revealed that the disk nut, which captures the valve stem in the valve main disk, had separated from the main disk. </br>The valve in question is a manually operated, non-active valve. The safety function of this valve is to retain system pressure. This safety function was not affected by separation of the stem nut from the valve disk.</br>However, other Figure 848 valves may have different safety related functions that could be affected by this type of failure. </br>(Flowserve has determined that) the Nuclear Industry needs to be notified concerning the potential defect and encouraged to inspect the operation of their valves, especially if they have a safety-related function in the plant that may be adversely affected. </br>The valves affected are Size 2 and smaller Edward Figure 848 valves manufactured by Rockwell International at the Sulphur Springs, Texas, and the Raleigh, North Carolina, manufacturing facilities prior to 1991. These valves may be tagged 'Rockwell', 'Rockwell Edward' or 'Edward'. The valves affected have the old design stem/disk assembly. </br>Valves with Figure Number A848 incorporate the new design stem/disk connection and are not affected.
