Notl.fications letters have been sent to the affected plants advising them of the condition, and recommending that the sleeve material be replaced with a lower friction Polytetrafluoroethylene (PTFE) material that would significantly reduce the required input operating torque, thereby reducing the risk of failure. of the stem material.
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 (CNl) has initiated the final phase of the Part 21 research and is currently. reviewing over 15,000 microfiche records from the original XOMOX Canada historical archive to determine if any other Nuclear Sites were impacted by the Subject Part 21. ihe investigation encompasses sales orders spanning from 1970 to 1993 and 2001 to present. CNI expects to complete the review by l0/30/2017, UPDATE 10/31/.2017 . . .
Crane Nuclear (CNI) 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 cove.rs 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 TUFFLINE- Safety Related and NuStamped Valves and Parts issued between 1970-1993 *
- XOMOX Crane Nuclear- Safety Related and N-Stamped Valves and parts issued from 200 l until present.
Note: Parts and valves were no longer supplied by XOMOX as safety-related or nuclear after 1993 until Crane Nuclear acquired :XOMOX in June 29, 2001.
The following sites in the table below were identified as safety related valves affected by this letter. All sites were supplied to customer ,cDelaval" which no longer exists. At the current pace of review, CNI eltpects to complete the review of the historical archive by 1/30/2018.

- The historical re.,earcb is complete. Our review of the records from 1973 tlirough 2001 identified 1.S valves that were supplied with a stem-sleeve material combination thnt could exceed the upper limit of yield strength of the valve, which could resu*t in fatigue/yielding of the stelll, thus preventing the valve from opening 1md closing while in service. Those 'Valves were supplied to:
