Subject:

Interim Report for 10 CFR Part 21 Investigation Report Notification of XOMOX Plug Valve High Torsional Stress in Stem

Dear Sir or Madam:

This letter provides interim notification of Crane Nuclear's Investigation into the subject Part 21 previously submitted to the NRC on 07/11/2017.

The information required for this notification is provided below:

(i) Name and address of the individual or infiividuals informing the Commission.

Samson Kay Manager of Sustaining Engineering Jennifer Btegovy Manager of Safety an.d Quality Crane Nuclear, Inc.

860 Remington Blvd Bolingbrook, IL 60440 (ii) ldentfjlcatjon of the basic component supplied for such facility or such activity wfthin the United States whic:h may fail to comply or contains a potential defect The plug valve designs provided for XO MOX model figure numbers 037 AX. 067EG1 and 037. These valves hove been identified f1S used in N-Stamp and/or safety related applications.

{Hi) Identification of the firm supplying the basit: component which fails to comply or contains a defect.

The valves subject to this notice were supplied by Xomox Corporation (Xomox) prior to 2001. Jn 20011 Xomox was acquired by Cra:re Co., which is also the parent company of CNI. At that time, CNf, the entity which is prov;d;ng this notice to the Commission, began providing support for the subject 11alves.

(i_v} Nature of the defect or failure to comply an*d the safety hazard which is created or could be created by such defect or failure to comply.

860 REMINGTON BOULEVARD NO. 921 TELEPHONE (630) 226-4900 FAX (630)2.2.6-4646 www.cni.ncnuolear.com BOLINGBROOK, IL. 60440 P. 2 The stem for the Subject valve models was identified as being undersized based on o/Jowable y~eld stress l1nalysis of the stem while in torsion. The high stress condition was due *to the high torque

.reqUired to seat/11Meat the plug when instaJJed with an Ultra High Molecular Weight Polyethylene

{UHMWPEJ sleeve material. High friction factor inherent with this material causes torsional stress to exceed the upper limit of yield strength of the valve which could result in fatigue/yielding of the stem, thus preventing the valve from opening and closing while in service.

Historical research performed thus far has not identified any notifications from the customer(s) regarding stem failure of the subject valves, indicating that the valves may still be in operation with no performance related or operating issues.

(11) rhe date on which the information of such defect or failure to comply was obtained.

Dote of Discovery of'Defect: 6/5/2017-5/9/2017 (vi) In the case of a basic component which contains a defect or fails to comp#~ the number and location of these components in use at, supplied for, being supplied for, or may be supplied for, manufactured, or being manufactured for one or more facilities or activities subject tO the regulations fn this part.

Historic.al researc.h of the XO MOX records is still in process at this time. However, we have currently identified seven (7) sites that have previously ordered these valves.

Notifications letters have been sent to the affected plants advising them of the condition, and recommending that the sleeve material be re pf aced with a lower friction Polytetraf/uoroethylene (PTFE) material that would significantly reduce the required input operating torque, thereby reducing the risk of failure of the stem mctterial.

XOMOX has been advised to modify design calculations to provide a larger margin for allowable yield strength of the stem material to ensure the stem is properly sized when Ultra High Molecular Weight Polyethylene {UHMWPE) sleeve material is used.

UPDATE 08/24/2017 Crane Nuclear (CNI} has initiate the final phase of the Part 21 research and is currently reviewing over 15,000 documents from the original XOMOX Canada historical archive to determine if any other Nuclear Sites were impacted by the Subject Part 21. The investig*ation encompasses sales orders spanning from 1970 to 1993 and 2001 to present. CNI expects to complete the review by 10/30/2017.

UPDATE 10/31/2017 Crane Nuclear (CNf} is has completed approximately 40% of the review of the historical archive and will not be able to complete the review by the previously requested 10/30/2017 deadline.

The historical review covers the following scope:

-XOMOX UK DEVON, ENGLAND -Safety Related and N-Stamped Valves/Parts issued between 1987 -1993

-XOMOX Canada & XOMOX A&M - Safety Related Parts from.1979-1993

-XOMOX Cincinnati TUFFLJNE -Safety Related and N-StQmped Valves and Parts issued between 1970-1993

-XOMOX Crane Nuclear-Safety Related and N-Stamped Valves and parts issued from 2001 until present.

Note; Parts and valvas were no longer supplied by XOMOX as safety-related or nuclear after 1993 until Crane Nuclear acquired XDMOX in June 29, 2001.

The following sites in the table below were identified as a safety related valves effected by this letter. All sites were supplied to customer uDelaval" which no longer exists. At the current pace o review, CNI expects to complete the review of the historical archive by 1/30/2018.
