Event Reports: Reactor glitches in Pennsylvania and Illinois

A couple of items from today’s NRC Event Notification page:

1. Late last night, operators at the Limerick nuclear power plant in Pennsylvania manually scrammed the Unit 1 reactor following failure of the unit’s Electro Hydraulic Control system. The EHC failure led to the reactor’s Low Press Turbine Intercept Valves failing closed. Of geographic interest: The Limerick nuclear power plant is 28 miles northwest of downtown Philadelphia. The Schuylkill River flows past Limerick through Philadelphia. I’m just sayin’….

2. Yesterday afternoon, radiation monitors at one of the spent fuel pools at the Quad Cities nuclear power plant went off in what was eventually determined to be an invalid activation. However, in response to the monitor activation, both reactor building’s ventilation systems isolated, as well as the control room ventilation system. Unfortunately, the Standby Gas Treatment system was already in operation due to previously planned testing, resulting in a pressure differential and the loss of secondary containment.

As I told you earlier this week, Quad Cities is one of three nuclear plants in Illinois that Exelon has threatened to close unless the state of Illinois adopts a ‘clean energy’ credit that would “recognize the nukes for their clean-air benefits and their dependability as a 24/7 power source.”

By the way, Exelon also owns the Limerick nuclear power plant.
