Ceramic Tubular Products, LLC announced the start of a 3-month in-reactor test of its duplex
silicon carbide fuel cladding at the MITR test reactor at the Massachusetts Institute of Technology. The test
will expose the product to neutron fluences, temperatures, pressures, and water chemistry prototypical of
commercial pressurized water reactors. Plans are underway to extend the test for an additional 9 months after
interim examination of the samples. Later testing of fueled samples in other test reactor(s) is also planned.

Ceramic Tubular Products, LLC has demonstrated that duplex silicon carbide cladding can be
fabricated in dimensions that are prototypical of zinc alloy fuel cladding. Samples have been made that closely
match the dimensions of standard "15x15" fuel cladding with an inside diameter of ~.350" and a wall thickness
of only .030". Preliminary testing shows that the cladding is capable of holding internal pressures up to
9000 psi and fails in a graceful manner to strains on the order of 10%. Development is planned to produce
dimensions consistent with "17x17" fuel element cladding dimensions of ~.320"ID x .025" wall thickness.

Gamma Engineering of Rockville, Maryland, and Innovative Technologies International (NovaTech)
of Lynchburg, Virginia, announced the formation of a joint venture company, Ceramic Tubular Products, LLC (CTP)
to focus on the development and commercialization of ceramic cladding for existing and future nuclear reactors.
CTP is a Maryland corporation headquartered in Rockville, Maryland, and has its primary
operations center in Lynchburg, Virginia.
