DEFECTS AND NONCOMPLIANCE PART 21 - CRANE NUCLEAR PRESSURE SEAL VALVE WITH RETAINING RINGS The following summary was excerpted from a facsimile received from Crane Nuclear:
"This letter provides interim notification of Crane Nuclear's investigation into ASME Boiler and Pressure Vessel Section III Code design Pressure Seal Valve orders for yokes with integral hubs acting as retaining rings.
"The information required for this notification is provided below:
"Name and address of the individual or individuals informing the Commission: Jason Klein, Sustaining Engineering Manager and Rosalie Nava, Director Safety and Quality, Crane Nuclear, 860 Remington Blvd.,
Bolingbrook, IL 60440 "Identification of the basic component supplied for such facility or such activity within the United States which may fail to comply or contains a potential defect: Pressure Seal Valve orders may potentially have misclassified material and non-destructive examination requirements for Yokes with integral hub retaining ring designs.
"Nature of the defect or failure to comply and the safety hazard which is created or could be created by such defect or failure to comply: Crane Nuclear 'Classification of Valve Parts', Procedure 03-107, provides guidance for appropriate material and NDE requirements for processing valve and valve part orders. The procedure is based on the ASME Code Case N-62, which is ASME B&PV Section III, 2015 Edition, Non-Mandatory Appendix HH
'Rules for Valve Internal and External Items'. A yoke incorporating a threaded hub should be treated in the same manner as a threaded retaining ring requiring the material to be purchased Safety Related, ASME B&PV Section II, Part D materials, and required NDE (reference Category 3 valve items per N-62). However, yokes with integral hubs acting as retaining rings may have been processed to material requirements for a yoke per Procedure 03-
08/07/2015 U.S. Nuclear Regulatory Commission Operations Center Event Report Page 2 107 and not a threaded retaining ring resulting in the incorrect material specification and non-destructive examination specified.
"Crane Nuclear has completed the sales orders search of the ASME Section III Code Pressure Seal Valve designs with retaining rings from 1992 to present. We identified a total of 112 orders that required review. Of these orders, three orders were supplied with non-compliant retaining ring material for the valve assemblies. The three orders are as follows:

"Crane Nuclear is currently investigating sales orders from 1968 to 1992. We require an additional 30-60 days to complete our review.
"Corrective action being taken by Crane Nuclear is to review documentation of the supplied material on the affected orders to determine if the yokes can be recertified as currently supplied, amend Crane Nuclear Procedure 03-1 07 to add figures reflecting configurations and clarify classifications, and train Engineering personnel by August 24, 2015.
"Crane Nuclear has notified the respective customers for the [three] orders that have been identified to date.
