(continued): The Semiscale Facility, used for reactor system thermal
hydraulic studies, was shut down due to NRC budgetary
constraints. It could be reactivated in 28 weeks and
operated for $4.0 million per year plus the cost of any
special modifications and analysis.
The Two-Phase Loop, used for two-phase water hydraulic
studies, was shut down due to budgetary constraints. It
could be reactivated in 26 weeks at a cost of $1.0 million.
The Air Water Loop, used to simulate two-phase water flow
conditions for instrumentation calibration, was shut down due
to budgetary constraints. It could be reactivated in
16 weeks at a cost of $70,000.
The Slowdown Loop, used for high pressure two-phase transient
calibration of instruments for the PBF and LOFT, was tied to
operation of these
facilities.
However, the Experimental Breeder Reactor II (EBR-II), the
Transient Reactor Test (TREAT) Facility, and the Zero Power
Plutonium Reactor (ZPPR) are operational and being utilized
for Safety research and other activities in support of
advanced concepts.
