[ RadSafe ] Example of Non-Regulated Materials

I noticed that Joel Grimm, Project Manager (Albuquerque DOE) was involved in
this project. Since there was no date on the presentation, is he still
involved?

 

"Regulated" Sources:

 

I remember having nothing but trouble in 1991 trying to find a disposal
solution for a 5 Ci Am/Be source for a neutron porosity well logging tool. I
finally hit upon transferring the source along with the probes and a 250 mCi
Cs source (gamma-gamma density) through the NRC to the IAEA and then to the
Geological Survey in Ljubljana, Slovenia (Geoloski Zavod Ljubljana). I had
worked with them back in the early 80s through the IAEA. Unfortunately the
Yugoslavian war broke-out nullifying the effort. The 250 mCi source was
eventually transferred to a college in Alabama for their physics program,
but the other source, although not "stranded", became a headache for several
more years.

 

But it is not only the companies involved in bankruptcy that had problems
during this time:

 

Remember that this was not the first instance of sources being stranded
through bankruptcy and sometimes the courts. The Goiana accident in Brazil
was one of these cases involving a "Regulated Source".

A general view of issues with sources was published in 1991 by the IAEA:

"Nature and magnitude of the problem of spent radiation sources"

In 1992, and in the wake of the Co-60 accident in Mexico, I was involved as
an IAEA expert to access site characterization and hydrogeology of two LLRW
facilities in Mexico: a proposed facility at Laguna Verde NPP, and an
existing LLRW facility at Maquixco. In my report, I recommended that the
Maquixco LLRW facility be closed and all source material removed and secured
based on the poor hydrogeological characteristics of the facility. Happily,
this was accomplished the following year.

Hello.

who will pay for this? ("pay" in the sense of "go to jail for life" or  

something like this). Well, I tell you: no one (because no one will  

assume his responsibility)
