PART 21 - UNDERSIZED PACKING GLANDS IN CERTAIN CRANE GATE VALVES
On 12/17/17, Brunswick Nuclear Plant experienced a packing gland blowout on an in-service Crane Nuclear, Inc., Figure Number 83 1/2 SPL, 10 inch by 8 inch by 10 inch, Bolted Bonnet Gate Valve. Crane Nuclear determined that component drawings for the 10 inch valve as well as the 6 inch by 4 inch by 6 inch Bolted Bonnet Gate Valve were in error. That error was corrected. Crane Nuclear is recommending that affected licensees replace the packing glands of the affected valves in their possession.
The affected licensees are Pilgrim Station, Cooper Nuclear Station, Browns Ferry Nuclear, and Brunswick Nuclear.
Should you have any questions regarding this matter, please contact Joyce Hamman, Director, Safety & Quality at (678) 451-2280, Burt Anderson, Site Leader, at (630) 226-4990, or Samson Kay, Engineering Manager at (630) 226-4983.
* * * UPDATE AT 1435 EDT ON 03/21/18 FROM SAMSON KAY TO DONG PARK * * *
The following information was provided as an update via fax:
"[Crane Nuclear, Inc.] Recommends one of the following actions be taken:
- The valve gland should be replaced to tighten clearances to meet MSS-SP-120 requirements.
- Install a packing washer in the current configuration that complies with MSS-SP-120 clearances. Use of a packing washer will allow for load to be evenly distributed across the packing to prevent extrusion through diametral clearances. Note, that existing drawings and bills of materials should be updated to match this configuration if this option is selected.
"Should you have any questions regarding this matter, please contact me, Joyce Hamman, Director, Safety & Quality at (678) 451-2280, Burt Anderson, Site Leader, at (630) 226-4990, or Samson Kay, Engineering Manager at (630) 226-4983."
