Warm seawater forces shutdown of Connecticut nuclear power plant

A Connecticut nuclear power unit at the Millstone plant has been shut down because water from Long Sound Sound was too warm to provide proper cooling, something which has never happened before.

Regulators changed rules in an attempt to keep the unit operational, something which hardly reassuring. This isn’t a teakettle we’re dealing with but rather a nuclear reactor. Rules shouldn’t be fudged to keep them open but apparently this happens routinely. Feel safer now?

The agency issued an “emergency license amendment” last week, allowing Millstone to use an average temperature of several readings. “It wasn’t enough to prevent us from shutting down.”

The closed unit generates 880 MW and uses water closer to the surface for cooling rather than colder deep water which the other unit, which remains open, uses.
