DAVID WALTHOUSEN LABORATORY REACTOR CRITICAL FACILITY RCF 17-01 April 28, 2017 Re: Operations Report for the Rensselaer Polytechnic Institute Reactor Critical Facility, NRC License CX-22, Docket Number 50-225. To Whom It May Concern: This document constitutes the Calendar.Year 2016 Operations Report of the RPI RCF to the USNRC and to Rensselaer management.

• The Reactor Critical Facility (RCF) operated successfully during calendar year 2016. The RCF was used for one laboratory course and two introductory courses in the Nuclear Engineering curricula.

The facility staff trained. three Synior who passed an NRC licensing exam in January 2016. Students from. Vermont Technical.c;::onege carried out experimer.ts"similarto those performed in the* lab6rat6ry'course.

This exp.eriment was sponsored by Knolls Atomic Power Laboratory.

Work proceeded on critical experiments with the 0.640 pitch lattice plates. Critical .measurements were performed with 327-pin and 333-pin configurations.

Some subcritical measurements were conducted with fewer pins. The SPERT(Fl) fuel is 4.81 w/o enriched high density U0 2 pellet fuel clad in stainless steel, so it is similar to power plant reactor fuel. The RCF is now the* only facility in the U.S. carrying out reactor physics critical experiments in support of the power reactor function.

These experiments are similar to pbwer reactor startup measurements.

A NRC inspection was performed in August 2016. NRC findings have been reported in other correspondence.

Training and proficiency requirements for all licensed operators have been reviewed and are current. 1)1e NSRB t.he same, however,Dr.

5. Changes, tests or experiments requiring authorization from the USNRC under lOCFRS0.59 a orb: None 6. Calculated integrated thermal power: Approximately 77.5 x 10-3 kw-hr for all of 2016. 7. There were no unplanned scrams in the report interval.

8. Maintenance operations were carried out and logged with satisfactory results. 9. There were no discharges of radioactive effluents.

10. Environmental monitor dosimetry is performed at the exclusion area fence (EMl through EM4), and at the site boundary fence (EMS and EM6). The environmental monitoring results are reported without background subtraction, and the accumulated dose to an off-site control monitor is reported separately.

The sum of the quarterly control readings from 2016 was 123 mrem. The sums of the gross readings and net dose results for 2016 are: Gross Net EMl U6mrem Omrem EM2 131 mrem 8mrem EM3 110 mrem Omrem EM4 107 mrem Omrem EMS 104 mrem Omrem EM6 131 mrem 8mrem 11. A total of 11 personnel monitoring badges recorded an accumulated dose greater than the minimum reportable dose of 10 mrem in at least one quarter of 2016, for a total collective dose of 226 mrem.
