p En*.rgy ' Production and Fuel Burn-up h
The Berkeley Research Reactor produced.126,014 kW-hours or 5.25 MW-days of energy during 1983. As there were 192 operating days in 1983, this corresponds to an average daily energy production of 656 kW-hours per op-
,y, erating day.
-In 1983, the Berkeley Research Reactor was critical approxi-I mately 270 hours0.00313 days <br />0.075 hours <br />4.464286e-4 weeks <br />1.02735e-4 months <br /> and was operated at full power (1 MW) for approximately 119 hours0.00138 days <br />0.0331 hours <br />1.967593e-4 weeks <br />4.52795e-5 months <br />.
j The total burn-up in 1983 was 5.6 grams elemental and 6.5 grams of isotope U-235.
I The total cumulative energy production since initial criticality is approximately 266.3 MW-days.
Nuclear Regulatory' Commission Inspection Inspections of the Berkeley Research Reactor safety were performed by the Nuclear Regulatory Commission Region V office in May of 1983.
No items of noncompliance to the Technical Specifications and Nuclear Regulatory Comrnission regulations were found during the inspections.
Operating Procedures The 'following new and revised operating and safety procedures were introduced in 1983:
