DOE-STD-3013-2000
Because of the shortcomings of the LOI method when applied to impure 94-1
materials, the MIS program has aggressively examined alternative methods for
measuring moisture and hydrogenous content. In particular, the following
methods have been evaluated carefully.
Thermal gravimetric analysis/mass spectroscopy
Supercritical carbon dioxide extraction
Interstitial gas analysis
Neutron moderation
A literature review was conducted recently to ensure that promising methods
have not been overlooked. [Berg/Eller 1999]
In May 1999 LANL recommended that both neutron moderation and supercritical
CO2 extraction/FTIR methods be deployed [Rubin, et al. 1999]. This
recommendation was endorsed by a peer review group with representation from
SRS, Hanford, RFETS, LLNL, and DOE/HQ. Continued method development was
recommended (especially for neutron moderation) to minimize limitations of each
technique at their current stage of development. Inclusion of other techniques
requires independent evaluation and DOE approval consistent with Item 5 of the
Foreword.
2) Qualification of the stabilization and packaging process would permit materials to
be stabilized and packaged without the requirement for measuring the moisture
content of every batch of material to be packaged.
The plan to qualify a process must be developed by the packaging site,
consistent with quality assurance requirements and practice at that site. The
plan must include the following information: 1) specific materials to be stabilized
and packaged; 2) process parameters (times, temperatures, glovebox humidity,
etc.) that define the process being qualified; 3) product testing program to
demonstrate process stability and product consistency; 4) post-qualification
materials testing needed to verify continued process control; 5) any changes to
storage surveillance requirements needed to assess storage safety; and
6) actions (such as including the process parameters in the facility Authorization
Basis) required to "institutionalize" the qualified process. If the materials to be
