| Title | Part 21 - Commercial Grade Cap Screws Provided with Safety Related Fisher Type 3570 Positioners |
| Event Description | The following information was provided by the reporting organization via fax:
Pursuant to 10 CFR 21.21(a)(2), Fisher Controls International LLC ('Fisher') is providing required written interim notification of a failure to comply concerning Type 3570 positioners when provided as safety-related equipment. On November 11, 2015, Fisher became aware of an issue with the dedication of a Type 3570 positioner. When replacement Type 3570 positioners are ordered, the two cap screws (SAE J429 Grade 5 cap screws/size 3/8-16x1.5) used for mounting the positioner to the actuator cylinder are also included. It was not clearly communicated to the end user that these mounting cap screws are included with the positioner. Further, the dedication plan only addresses the 3570 positioner and does not include dedication of the mounting cap screws. As a result, these cap screws had not been dedicated on any safety-related Type 3570 positioner orders. There is no reason to believe any of the cap screws supplied were defective, only that they were not dedicated and were therefore supplied as commercial grade items. There have been no reported failures of the cap screws in question. An extent-of-condition investigation is underway to identify all potentially affected bolt-on accessories. Any identified affected products will be reported per the requirements of 10 CFR 21.21 (b). This extent-of-condition review is expected to be completed by January 29, 2016. Corrective Action 1791 has been opened to document corrective actions taken to prevent reoccurrence. Should there be any further questions concerning this matter, please contact Benjamin Ahrens, Manager, Quality by email at Benjamin.Ahrens@Emerson.com or via phone at 641-754-2249. Individual informing the NRC: Chad Engle, Director, Nuclear Business Unit, Fisher Controls International LLC, phone (641) 754-3011.
The following information is summarized from a fax received from Emerson Process Management (Fisher Controls): On January 22, 2016, Fisher Controls completed their extent-of-condition investigation and determined that seven of their thirty two product series have the potential to include non-dedicated cap screws and mounting studs. The vendor plans to complete their final report within 45 days. Notified R1DO (Rogge), R2DO (Musser), R3DO (Kozak), R4DO (Pick) and the Part 21 group via email.
The following information is summarized from an email received from Emerson Process Management (Fisher Controls): The supplied instrument assemblies in question were subjected to the processing requirements of Fisher Controls FMP2K27 (Control of Commercial Grade Items to be Dedicated for Use in Nuclear Safety-Related Applications) and were supplied as safety-related components. However, Fisher supplied various mounting parts (in addition to the requested product) that were not processed under FMP2K27; thus, such parts were supplied as commercial items. This issue was first discovered in relation to the cap screws used for mounting a 3570 positioner (please see Interim Report dated 01/08/2016). Fisher conducted an extent-of-condition investigation to include all safety-related actuator-mounted accessories. In total, thirty -two (32) actuator-mounted item types were investigated. It is Fisher's opinion the failures to dedicate these mounting accessories do not pose an inherent safety risk. Additionally, there are no known field issues with respect to the affected equipment and all such non-dedicated equipment passed the required standard testing. Each affected customer needs to: (i) evaluate the application of each referenced item number for all respective orders; (ii) determine whether the incorrectly processed mounting parts are in violation of regulatory requirements; (iii) contact Fisher or otherwise arrange for the procurement of properly processed mounting parts for use in those applications found to be in violation. In addition, a Corrective Action Request (CAR 1791) has been initiated by Fisher to prevent reoccurrence of this issue. Notified R1DO (Dimitriadis), R2DO (Suggs), R3DO (Riemer), R4DO (Proulx), and the Part 21 group via email. |
