SUMMARY

OF OPERATING EXPERIENCE )

The reactor was in operation a total of 5.75 hours8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br /> during the period. This includes time when the reactor was j operated for surveillances where the reactor was not actually critical. The total operating time for the period was i due to fulfilling sutveillance requirements. The LOPRA is in the process of decommissioning and is awaiting a I

decommissioning order from the Nuclear Regulatory Commission.

II. TABULATION OF OPERATIONS Sun'eillances - 5.75 hours8.680556e-4 days <br />0.0208 hours <br />1.240079e-4 weeks <br />2.85375e-5 months <br /> l Hours C titical* and Energy 3.2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> 0.0023 Mw-hrs

• This includes time where the reactor was sub<ritical during the control rod calibration. Virtually all of the  ;

.. energy generated was due to the power calibration surveillance.  ;

111. EMERGENCY SHUTDOWNS AND INADVERTENT SCRAMS .

4

!: Two linear power scmnis occurred during the performance of sum,illances. Both of these scrams occurred due to  ;

noise spikes in the linear channel.  ;

IV. MAINTENANCE i

A significant number of man-hours were devoted to troubleshooting the poison control rod drive indication before i

. declaring the LOPRA inoperative.

i

, V. CONDITIONS UNDER SECTION 50.59 OF 10CFR50

There were no changes to procedures, new experiments, or 50.59 reviews performed during the reporting period.

VI., VII., Vill. RADIOACTIVE RELEASE / RADIATION EXPOSURE {

Because of the low power and infrequent use of the LOPRA, its operation does not contribute to the release of cfiluents. Personnct radiation exposures for the laboratory are given in the Annual Report for the Advanced
