Credible threats vs. Threats is not an exact science, but you can't evacuate or cause panic every time a person makes one - or you'd just multiply the number of hoaxes to get that reaction.
There are things that are not released to the general public on regularity - but those in various levels are aware of - that help in determining factors around various threats or potential threats.
I guess we rely on the authorities to determine how credible a threat is, but I don't count on them to be forthcoming with information in the event of some emergencies, like Fermi I meltdown. BRD, hiding under the covers just doesn't work against some things, like radiation. I think this is another case of the government saying people are too stupid. Stupid or not, citizens have a right to self-determination.
I guess to keep Marilyn happy we will discuss and dispel the myths, rumors, and accusations of Fermi I and of radiation and pollution - without any citations
I realize the NRC is the "man" who you don't trust but it provides facts.
Fermi, Unit 1
1.0 Site Identification
Type of Site: Power Reactor Facility
Location: Newport, MI
License No.: DRP-9
Docket No.: 50-16
License Status: DECON
Project Manager: Ted Smith
2.0 Site Status Summary
The Enrico Fermi Atomic Power Plant, Unit 1 (Fermi 1) is located in Monroe County, Michigan. The site boundary is completely contained within the Fermi 2 site boundary, adjacent to Lake Erie. The site consists of six main buildings and several smaller gallery buildings and interconnections. Fermi 1 has an onsite groundwater monitoring program, which has not identified any groundwater contamination
due to Fermi 1 operations.
Fermi 1 was a fast breeder reactor power plant cooled by sodium and operated at essentially atmospheric pressure. The reactor plant was designed for a maximum capacity of 430 Megawatt (Mwt); however, the maximum reactor power with the first core loading (Core A) was 200 Mwt. The primary system was filled with sodium in December of 1960 and criticality was achieved in August 1963. The reactor was tested at low power in its first couple years of operation. Power ascension testing above 1 Mwt commenced in December 1965, immediately following receipt of the high power operating license. In October 1966, during a power ascension, a zirconium plate at the bottom of the reactor vessel became loose and blocked sodium coolant flow to some fuel subassemblies. Two subassemblies started to melt. Radiation monitors alarmed and the operators manually shut down the reactor. No abnormal releases to the environment occurred
. Three years and nine months later, the cause had been determined, cleanup completed, fuel replaced, and Fermi 1 was restarted. In 1972, the core was approaching the burnup limit. In November 1972, the Power Reactor Development Company made the decision to decommission Fermi 1. The fuel and blanket subassemblies were shipped offsite in 1973. The non-radioactive secondary sodium system was drained and the sodium sent to Fike Chemical Company. The radioactive primary sodium was stored in storage tanks and in 55 gallon drums until the sodium was shipped offsite in 1984
. Decommissioning of the Fermi 1 plant was originally completed in December 1975. The license for Fermi 1 expires in 2025.
3.0 Major Technical or Regulatory Issues
The facility is currently transitioning from active decommissioning for the remainder of 2011, and is expected to return to safe storage in early 2012.There is no spent fuel onsite. Bulk sodium has been removed from the site, and the reactor vessel has been grouted and is being removed
