these two classes and to provide information upon which corrective or other action
can be based.
The surveillance program should document the surveillance "philosophy" in terms of
the characteristics described above. Then, it should apply that philosophy to the
specific storage situations that may be encountered. For example, in a facility that
relies on package integrity for public safety (i.e., where the container is designated
safety class") and in which the packages are easily accessed and inspected, a
relatively extensive surveillance inspection would be expected. In a facility that does
not rely on package integrity for public safety, where access to the packages is
difficult, and where inspection involves a relatively high personnel radiation dose, the
surveillance inspection would be expected to be less extensive than in the previous
The surveillance program should identify sources of information/data to be used in
establishing inspection frequency, sample size and composition, etc. As information
on these packages is accumulated, it should be shared among the sites and included
in the information base. It is recommended that samples of materials typical of those
being stored be placed in a "shelf-life" program in which the condition of the storage
packages can be evaluated over long periods of time to give insight into the behavior
of the contained materials and into interactions between the materials and the
container; and that this information also be included in the surveillance information
base. Finally, it is recommended that the sites storing plutonium metals and oxides
and those preparing such materials for storage collaborate to the extent feasible in
developing their site programs, so that both consistency in approach and flexibility in
storage location can be maintained.
The surveillance program should identify possible courses of action to be taken in the
event of a an unexpected surveillance finding, and guidance on selecting the
appropriate action. This guidance should be directed toward identifying the event as
either an anomaly or a systemic issue, and toward establishing a plan for dealing
with the matter.
Certain efficiencies may be achieved if the frequency of surveillance is integrated
with the physical inventory program as prescribed in DOE 5633.3B.
