Work is under way to decommission the Heavy Water Components
Test Reactor, which had been used to test experimental fuel
assemblies for commercial heavy-water power reactors. SRS is
scheduled to remove the dome of the reactor this month (January
2011). Workers also will displace the reactor vessel and steam
generators, grout the remaining structure in place, and install
a concrete cover over the reactor's footprint A robotic device
named Tizzy was retrofitted by Savannah River Remediation (SRR)
employees to collect and remove tank waste. Using $100,000 from
the Recovery Act, SRR designed and built Tizzy. Here the robot
is being tested on a mock-up of a waste tank During the early
1950s, SRS began to produce materials used in nuclear weapons,
primarily tritium and plutonium-239. Five reactors were built to
produce nuclear materials. Support facilities, including two
chemical separations plants, a heavy water extraction plant, a
nuclear fuel and target fabrication facility, a tritium
extraction facility and was
