Borchardt led the call. (44 folks on the call)

* Focus on Fukushima Daiichi Unit 1. The belief is the explosion occurred in the reactor building (secondary containment) either from a steam or hydrogen explosion. Possible the operators choose to depressurize the containment through the standby gas treatment system (in secondary containment). Steam or hydrogen may have accumulated in the upper part of the reactor building and blew of a thin roof. Seawater possibly being used in two ways and that the reactor is now stable:

1. Borated seawater being injected into the reactor vessel and/or
2. Seawater is pumped to flood the lower part of the reactor building (secondary containment) around the outside of the torus/suppression pool. This would be done to provide external cooling to the torus and lower primary containment.

” There was a Deputy Principals meeting today and focus of discussion was on nuclear event. The USAID Disaster Assistance Response Team (DART) is on its way to Japan. NRC sending two experts to support.

* NRC posture continues to be White House is lead for U.S. response. NRC available to support.

* On media front, Eliot said the strategy is to follow the above hierarchy in communications. Regarding NRC, he noted that news cycle is slow (weekend) now but will pickup with respect to wanting more NRC visibility by Monday.

* Former Chairman Diaz and Klein to make media circuit and essentially carrying NRC key messages as private citizens.

* Borchardt noted that the Chairman has spoken to each Commissioner regarding comm.. strategies and other matters.

* U.S. Industry/NEI had a telecom/meeting this afternoon to discuss any needs to support Japanese.

* Ops center haa no info on Daini than the media reports.

NRC actions:

1. Continue to monitor events in Japan

2. Reach out to IAEA (again) and get IAEA to be the central lead in response. NRC unsuccessful so far. Attempting to get Denis Flory at IAEA. Looking to not burden Japanese with multiple nation support that is not coordinated.

3. Further develop Q&A as the attention will start to turn to US plants and our level of preparedness/protection from seismic and floods.

4. Keep interacting with DHS on potential plume plots and modeling capability, etc…

NEXT Telcon updates will be at 23:30 and 07:30.
