Re: Release of Site Vehicles

["Robert Denne" <rdenne@worldnet.att.net>]

Not sure about the DOE but from the NRC perspective a survey is defined as
an assessment and does not necessarily require physical measurement.  We use
this quite a bit in the non-DOE world, particularly when talking about
survey for alpha.

Lay down plastic. Set up step-off pads.  Maintain direct HP Supervision.
With the right controls it is easy to assess that the vehicle is not
contaminated by a combination of physical survey of highly suspect areas and
non-physical survey of the others (reasonable assumption).  I agree with Dan
that to truly release a vehicle would be next to impossible and very costly,
if a 100% physical survey was required.  We have to be able to assess each
situation on its own and minimize risk to a comfortable level both for us
and our regulators.

We use a roll around floor monitor for beds of trucks and hand frisk the
tires and other areas we suspect may have become contaminated.  We also take
a random number of swipes in those areas to check for loose contamination.

> Dave, although it is done, I think you understand the real problem.  One
really can not release a vehicle from a contaminated area you just can not
get into all the tight spaces to do the survey.  At Defense Nuclear sites we
have not addressed this problem from the Board's perspective because it is
not safety but public fear and superstition and legal aspects which drive
this problem.  If I were Radcon Manager at a DOE site I would prohibit any
vehicles from entering a contaminated (loose surface) site.  This means that
to get a vehicle in you have to clean up the site.  Tough decision but it is
better than the options 1) scrap the vehicle or 2) potentially ending up on
the news.
