Pakistan Research Reactor (PARR-1) went critical in
1965 with HEU fuel. The reactor core was converted to
LEU fuel with power upgradation from 5 MW to 10 MW in
1992. The reactor has been operated with LEU fuel for
about 10,000 hours and has produced about 66,000 MWh
energy up to now. Average burn up of the irradiated fuel
is about 42 %. The fuel performance during the last 12
years has been excellent. Post irradiation visual
inspection of the fuel has revealed no abnormality.
During operation there have been no signs of releases in
the pool water establishing the full integrity of this
fuel. The reactor has been mainly utilized for
radioisotope production, beam tube experiments including
neutron diffraction studies, neutron radiography etc.
Studies have been completed to operate the reactor with
a mixed core (HEU + LEU) to utilize the less burned HEU
fuel elements. A major project of production of fission
Moly using PARR-1 is in the final stages.
