Subject: March 21, 2011- 0730- CA Briefing On Japan Reactor Accidents

The following is a synopsis of the briefing with changes or noteworthy items underlined:

More at 2000 Monday from the RDO …. Mr. John RogQe….

Status of Fukushima Daiichi Units:

Unit 1-
No Significant Change

Unit 2-
TEPCO has offsite power to an aux transformer- Working to restore control room envelope and ventilation, and
switchgear/pumps/etc
Primary Containment intact as RCS is at a positive pressure

Unit 3-
Reports of white smoke reported but source or significance not known
SFP now has water in it.
No venting is planned

Unit 4-
SFP now has water in it.

Other Issues-
Unit 5 and Unit 6- Both have AC Power
Unit 5 and Unit 6 SFPs Being Positively Cooled

Bechtel spray system left Perth, Australia at appr 6:30 EDT March 21. Single train with 2 techs, unsure if
TEPCO will use it.

The band of elevated dose rates up to 18 mi from plant to the northwest seems to coincide with the only time
wind was blowing in that direction being when the “lube oil fire” occurred on Unit 4 when we thought a H2
detonation and SFP fire occurred.

When I receive the normal status attachment I will send it.
