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.
