SUMMARY

OF,

~

The LOPRA was scheduled for operation a total of 37 hours4.282407e-4 days <br />0.0103 hours <br />6.117725e-5 weeks <br />1.40785e-5 months <br /> and was in actual operation .a total of 26.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br />. Scheduled operations averaged 3.1 hours1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> / month and actual operation 2.2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> / month. Use of the LOPRA was for an' ' Approach to Critical' experiment for students and operator training in which the above experiment may be completed. The types and percentages of usage for this time were:

Approach to Critical Experiments 32%

Operator Training 27%

Measurements for Surveil) ince Requirements 41%

There were no new e;na aents or changes in ' facility design, performance characteristics, and operating procedures during this period.

II. TABULATION OF, OPERATION Hours Critical

• and Energy Steady State Operation 26.7 hours8.101852e-5 days <br />0.00194 hours <br />1.157407e-5 weeks <br />2.6635e-6 months <br /> 0.0016 FM-hrs

• This includes time for loading fuel elements during' the. approach. to critical experiment. Actual crif.ical time would be about 30% of this value.

III. EMERGENCY SHITrDOWNS - None IV. MAINTENANCE The fuel elements were inspected in July and showed no excessive signs of corrosion. There were no leaking elements detected.

V. CONDITIONS UNDER SECTION 50.59 of 10 CFR 50.

There were no changes to the system, procedures, or new experiments during this period.

VI...VII.,-VIII. RADIOACTIVITY Because of the low power and infrequent use of the LOPRA, its operation does not contribute to the release of effluents. Personnel records for the

-laboratory are given in the Annual Report for the Advanced TRIGA Reactor, License No. R-115,_ dated February 29, 1950 (Docket No. 50-151).
