| Title | Part 21 Report - Defective Asme Sa-193, Grade 6 Cap Screw Material |
| Event Description | The following information was obtained from Fisher Controls International via facsimile:
Fisher Information Notice (FIN 2009-01, dated February 2, 2009) was issued to notify customers of an issue reported to Fisher by Duke Energy. [Fisher has] informed [their] customers of record of this circumstance in accordance with 21.21 (b) of 10CFR21 because Fisher Controls International LLC, is not aware of each and every application or system design and cannot determine whether an anomaly could cause a defect or "failure to comply," relating to a substantial safety hazard. In particular, this Information Notice deals with customer orders that used improperly heat treated cap screws provided by Texas Bolt Company (Texas Bolt Order 204653, Certified by Texas Bolt Company, April 20, 1987). Receipt of this notice does not necessarily mean that the recipient has been shipped any of the subject equipment. It is expected that the recipients of this notice will review the information for applicability to their facilities, and if required, take the appropriate action as described in the section at the end of this notice. This notice applies only to customer orders processed by Posi-Seal International that used the 100 quantity lot of hex head cap screws identified by Texas Bolt Company Material Certification Report Number 001.87-1758, certified by Texas Bolt Company, April 20, 1987. Fisher was informed by Duke Energy that there have been failures of ASME SA-193 Grade B6 hex head cap screws at the Catawba Nuclear Station. These bolts are used on various size Posi-Seal butterfly valves to maintain a pressure seal on the outboard side of the valve body. Failure of these bolts will impair the pressure retaining capability of the valve body. Based on the experiences at Duke Energy, it is possible that a defective batch of cap screws were used by Posi-Seal around 1987. Fisher Controls International has attempted to determine a complete list of valve serial numbers that may have used bolts from this particular lot. Unfortunately, Fisher Controls International's review of available Posi-Seal records cannot provide validation of its completeness. It is recommended that customers verify if the QA documentation package, provided with the valve, contains a copy of the cap screw material certification attached to this information notice. If so, Fisher Controls International recommends that the subject cap screws be replaced. Fisher Controls requests that the recipient of this notice review it and take appropriate action in accordance with 10CFR21. If there are any technical questions or concerns, contact: Michael Wedemeyer Manager, Quality Fisher Controls International LLC 205 South Center Street Marshalltown, IA 50158 Fax: (641) 754-2854 Phone: (641) 754-2066 Michael.Wedemeyer@.Emerson.com Possible domestic constructions with defective cap screw material (Posi-Seal part number 131550, drawing number 5200-001) include McGuire, Catawba and Indian Point. |
