Illinois nuke shut down because of cracked weld

NRC Event Reports today included a notification that the operators of the LaSalle nuclear power plant in Illinois were putting the Unit 1 reactor in a Technical Specification due to a cracked weld on a warmup valve in the Reactor Core Isolation Cooling system. The cracked weld resulted in a Pressure Boundary Leakage, and would have required a reactor scram if the plant had been at power. The problem was discovered when operators attempted to restart the reactor following a previous outage.
