"Exploration of Ion-Exchanged Glass for Seals Application,"
33rd ESARDA Annual Meeting: Symposium on Safeguards and Nuclear Material Management
, May 16–20, 2011, Budapest, Hungary.
As the nuclear industry grows around the globe, it brings with
it a need for more safeguards and proliferation resistant
technologies. The International Atomic Energy Agency (IAEA) depends
on effective containment and surveillance (C/S) technologies
and methods for maintaining continuity of knowledge over
nuclear assets. Tags and seals, a subset of C/S technologies, are
an area where innovation has been relatively stagnant for the
past fifteen years (pickett lecture). Seals are used
to maintain the integrity of monitoring enclosures,
containers, or perhaps a point of entry. Tags are used like
barcodes, as unique identifiers to account for separate items. It
is necessary to investigate technologies not previously used
in this field in order to defend against emerging threats and
methods of defeat.
Based on a gap analysis of tags and seals currently being used
by the IAEA, completed with the input of several subject
matter experts, the technology selected for investigation was
ion-exchanged glass. Ion-exchanged glass is relatively
inexpensive, has high strength, and can be used in a variety
of applications. If identical pieces of glass are exchanged
under the same conditions and subjected to the same point
load, the fracture patterns produced can be compared and used as a
verification measure. This technology has the potential to be
used in passive seal applications.
