As reported in NHK Japanese (12/20/2011):
Chairman Jaczko of the US Nuclear Regulatory Commission visited Fukushima I Nuclear Power Plant for the first time since the accident started, and gave a press conference afterwards in Tokyo. He said the announcement of "a cold shutdown state" by the Japanese government was a proper decision and that it would be important to share the information regarding the accident with the international communities to prevent similar accidents from happening again.
Chairman Jaczko of the US Nuclear Regulatory Commission visited Fukushima I Nuclear Power Plant on December 19 for the fist time since the accident started, and held a press conference in the afternoon of December 20 at the US Embassy in Tokyo.
In the press conference, Chairman Jaczko pointed out to the various countermeasures against contingencies have been installed at Fukushima I Nuclear Power Plant after the accident, and said "The temperatures inside the reactors have gone down enough", indicating the declaration by the Japanese government of "a cold shutdown state" and the completion of the "Step 2" of the roadmap toward the restoration from the accident was a proper decision.
He then referred to the Japan-US cooperation regarding the safety countermeasures for nuclear power plants, and said "Because of the [Fukushima] accident, our relationship has gotten stronger". He also said "The international communities are very interested in how the accident information will be shared", indicating the importance of international information sharing of the accident.
And here's one from Bloomberg (12/20/2011):
The melted fuel in the reactors at the Fukushima Dai-Ichi nuclear plant has cooled enough to prevent any further releases of radiation beyond the station, Jaczko told reporters today in Tokyo after a visit to the station.
He spoke four days after Japanese officials declared that the reactors, which were damaged by the March 11 earthquake and tsunami, have been brought to a state known as cold shutdown. Some nuclear scientists disputed that the term accurately described conditions at the plant. Jaczko called the declaration a “tremendous milestone.”
“I feel very comfortable that they have completed really the requirements that are necessary to move on to the next stage,” he said. “There’s really no energy left in the reactor to have an off-site release of radiation.”
