1. Sunday afternoon, operators at the Palisades nuclear plant in Michigan declared a primary coolant loop to be inoperable due to a steam leak. Since the leak could not be investigated with the reactor running, the plant entered a Technical Specification shutdown, which requires that the unit be fully shut down within six hours. The Palisades nuclear power plant sits on Lake Michigan about sixty miles northeast of Chicago.
2. Meanwhile, on the shores of Lake Ontario, the Nine Mile Point nuclear power plant in New York experienced an automatic shutdown Saturday morning due to a low water level reading in the reactor for Unit 1. The reactor’s High Pressure Coolant Injection System activated during the incident.
3. The FitzPatrick nuclear power plant shares a 900 acre site with Nine Mile Point, and its sole reactor had a similar problem last night. The reactor shut down automatically following a turbine trip, and the Reactor Core Isolation Cooling system activated.
4. And in Florida, a contract supervisor at the Crystal River nuclear power plant tested positive for an unspecified substance during a for-cause Fitness for Duty screening. For-cause tests are unusually an indication that the employee’s behavior appeared impaired. The supervisor’s access to the plant has been terminated.
