RE: Receipt of Type B Packages

["Charlie Migliore" <cmigliore@envirocareutah.com>]

"Received" could be defined as a license condition. Likewise for the "3

hours".



By our license for instance, truck shipments are considered "in transit"

until the truck driver leaves the site.

Subject:	Re: Receipt of Type B Packages



Here are a few things to keep in mind:



49 CFR 173.403... "Package means, for Class 7 (radioactive) materials, the

packaging together with its radioactive contents AS PRESENTED FOR

TRANSPORT..."  [emphasis mine]



10 CFR 20.1906

(b) Each licensee shall -

(1) Monitor the EXTERNAL SURFACES [emphasis mine] of a labeled package for

radioactive contamination ...

(2) Monitor the external surfaces of a labeled package for radiation

levels..."

...

(c) The licensee shall perform the monitoring required by paragraph (b) of

this section as soon as practical after receipt of the package, but not

later

than 3 hours after the package is received at the licensee's facility..."



Interpretations:



"Received" is not defined in the regulations, but a reasonable

interpretation

is that, for a cask shipment, the package is considered "received" when the

cask trailer or rail car is disconnected from its motive power, i.e.

locomotive or tractor..



Since the impact limiters are an essential part of the package "as presented

for transport," and the receipt survey is only for the external surfaces of

the package "as presented for transport," surveying under the impact

limiters

is NOT part of the receipt survey.



The three hours is a hard limit, which I interpret to mean completing the

survey to the point where any contamination levels or dose rates above

established limits can be identified.  The % of the package to smear or scan

is a judgment call, but it should be sufficient to identify any potential

violations.  It dose not mean that the survey has to be fully documented and

reviewed.



The opinions expressed are strictly mine.

It's not about dose, it's about trust.

Curies forever.
