Operating Experience OE12590 - Inadequate Piping Modification Controls Causes System Inoperability A pre-refuel outage inspection of seismic snubbers found that two snubbers associated with a support on an operable ECCS system were fully extended. The system was declared inoperable pending evaluation. When the snubbers were removed to evaluate their condition, the piping in the vicinity of the snubbers moved in the upward direction. Spring cans associated with this piping were then adjusted to relieve the upward force exerted on the piping. Though these adjustments lessened the upward piping displacement, the piping remained too high for proper reinstallation of the snubbers.
Lessons Learned: Work practices that contributed to the event Included: design and work concentration at the point of the cut without evaluation of the effect of the cut on the local system piping and supports; the absence of an as-left design verification of affected system piping; not removing snubbers that could be damaged by piping movement; the Installation of temporary restraints as determined by the work group with engineering guidance rather than by a preplanned restraint scheme; and not pinning spring cans.
Safety Snippet If your load starts to slip, get out of the way - quick December 1997 An employee at a hospital was pushing a food cart down a ramp when she lost control of it. As she tried to stop the cart, she was crushed between it and a wall. She was hospitalized for a fractured ankle and a lacerated ear.
