Sandia National Laboratories results for the 2010 criticality accident dosimetry exercise, at the CALIBAN reactor, CEA Valduc France.

“…PNAD locations are indicated in Table B-1. The Quick-scan procedure uses a nomogram based upon a bare Godiva spectrum (spectrum #12, Ward et al, [1996]). This spectrum was considered to be the most representative for work at Sandia.…”

“…The SNL Personal Nuclear Accident Dosimeter (PNAD) contains six different types of activation foils (Figure 1) and is a sealed unit (Ward et al, 1996). The dosimeter has an indefinite shelf life and remains inert until it becomes activated.…”

“…Figure 3 is the nomogram used by SNL monitoring personnel to quickly sort individuals by estimated exposure level (Ward et al, 1996;Hill 2004). This provides Health Physics and Medical personnel with a triage process.…”

“…They are not packed by weight but by their level of r 300 mR./hr (Ward 1996 The waste drums have been sealed manually. After the lid cover was placed on the drum, the drum's closure ring (c-ring) was slid around the lid, fastening the lid to the drum.…”

“…The 55 gallon drums' weights vary from 100 to 600 pounds. They are not packed by weight but by theirlevel of radioactivity, which does not exceed 300 mremlhr (Ward 1996). The objective of this research is to use a robot to open waste drums nondestructively.…”
