But, but...we meant something else when we said it was a cold shutdown. It is exactly the same as cold shutdown, only different.

The long and winding road to an explanation of 'cold shutdown'.

The Nuclear Energy Institute(NEI) parses 'Tepcospeak'.

TEPCO understood this important nuance to achieving “cold shutdown” early on this year when it developed its initial recovery plans and developed a new term, “cold shutdown condition,” which applies to how they are bringing the reactors to stable condition. Their definition is as follows:

Temperature of RPV bottom is, in general, below 100 degrees Celsius.
Release of radioactive materials from PCV is under control and public radiation exposure by additional release is being significantly held down. (Not exceed 1 mSv/y at the site boundary as a target.)
By their definition, the Fukushima Daiichi reactors will reach “cold shutdown condition” once they are below boiling point and are no longer releasing significant amounts of radiation into the atmosphere.

This new definition, thus, has an important distinction between the more commonly used “cold shutdown,” which typically takes place at a nuclear plant under normal conditions.

'By their definition' kinda says it all.
