21.21 UNSPECIFIED PARAGRAPH PART 21 - ERROR IN VALVE BODY DRAWING The purpose of this Fisher Information Notice (FIN) is to alert Duke Energy that as of February 25, 2011, Fisher Controls International LLC became aware of the possibility of a situation which may affect the performance of the applicable equipment provided to McGuire Nuclear Station. Specifically, an error was discovered on valve body drawing V1i12298, when, during a revision process on Revision B of the drawing, a dimension was omitted that set the depth of the valve shaft bearing bore. This error resulted in a greater possible variation of bearing position in the valve shaft bore. If the error was large, the valve could not be assembled which was not the case for these valves. The valves assembled without incident and passed the operational testing, including a seat leakage test, with no anomalies. In the case that the bearing position error was slight, it is possible that the seal and disc could experience more wear than normal and increased leakage would result. Because these valves are equipped with manual operators, Fisher expects that these valves will not be cycled enough to experience any of the potential problems described above.
This equipment included NPS 4, Class 150, Fisher Type Al 1 Butterfly Valve Assemblies equipped with Fisher Leverlock Manual Actuators. The NPS 4, Al1 is a butterfly valve that uses internal bearings (located on either side of the disc) to provide a radial wear surface for shaft rotation and also serve as a centering system for the disc in the waterway. Centering of the disc is accomplished with a wear surface on the end of the bearings adjacent to the side of the disc. Lateral positioning of the disc is accomplished by controlling the length of the bearings and the depth of the bored holes in the body that accept the bearings.
Fisher has revised the drawings to ensure that this issue is corrected.

The NPS 4, All is a butterfly valve that uses internal bearings (located on either side of the disc) to provide a radial wear surface for shaft rotation and also serve as a centering system for the disc in the waterway. Centering of the disc is accomplished with a wear surface on the end of the bearings adjacent to the side of the disc. Lateral positioning of the disc is accomplished by controlling the length of the bearings and the depth of the bored holes in the body that accept the bearings.
Specifically, an error was discovered on valve body drawing V1 12298, when, during a revision process on Revision B of the drawing, a dimension was omitted that set the depth of the valve shaft bearing bore. This error resulted in a greater possible variation of bearing position in the valve shaft bore. Ifthe error was large, the valve could not be assembled which was not the case for these valves. The valves assembled without incident and passed the operational testing, including a seat leakage test, with no anomalies.
