Japan is dangerously contaminated by radioactivity

United States: Alabama

While a tornado partially knocked out at the Browns Ferry reactors in Alabama in April, power began to be restored within a month without incident.

United States: Nebraska

The flood waters in the Missouri continue to pose a danger to the Fort Calhoun nuclear plant in Nebraska. As you may know, an electrical fire at the spent fuel pools at Fort Calhoun temporarily knocked out power for cooling, and the operator flooded the containment building.

So far, I have seen no evidence of any release of radiation, although there are a number of worrying factors in the form of a “perfect storm” which could – in a worst-case scenario – lead to an accident.

The latest updates include:

An “event” at the Fort Calhoun plant was reported to the Nuclear Regulatory Commission:
Facility: FORT CALHOUN
Notification Date: 06/16/2011
Notification Time: 14:46 [ET]
Event Date: 06/16/2011
Event Time: 12:30 [CDT]

Event Text: ADDITIONAL PENETRATION IDENTIFIED FOR MITIGATION DURING WALKDOWN

“Operations identified a potential flooding issue in the Intake Structure 1007 ft. 6 in. level. The area of concern is a the hole in the floor at the 1007 ft. 6 in. level where the relief valve from FP-1A discharge pipe goes through the raw pump bay and discharges into the intake cell. There is one penetration of concern. Flooding through this penetration could have impacted the ability of the station’s Raw Water (RW) pumps to perform their design accident mitigation functions.

“Efforts are in progress to seal the penetration.

“This eight-hour notification is being made pursuant to 10 CFR 50.72 (b)(3)(v).”

The licensee notified the NRC Resident Inspector.

WOWT reports:

[Fort Calhoun Nuclear Power Plant's chief nuclear officer, Dave Bannister] said for the plant to get to a disaster level, floodwater would have to rise three and a half feet above where it stands now.
