Idaho State University AGN-201M Reactor Facility License R-110, Docket No. 50-284 Annual Operating Report for 2015 Calendar Year

1. Narrative Summary A. Changes in Facility Design, Performance Characteristics, and Operating Procedures:

There were no changes in facility design, performance characteristics, and operating procedures* relating to reactor safety during the reporting period.

B. Results of Major Surveillance Tests and Inspections:

(1) The period, count rate, and power level measuring channels were calibrated and set points were verified. Channels 1, 2, & 3 were tested on 5/29/2015, 56/1/2015 & 6/1/2015 respectively.

(2) Power level (3/16/2015) and period check (6/1/2015) experiments were performed with satisfactory results.

(3) The shield water tank was inspected (6/2/2015) and no leaks or excessive corrosion were observed. The water level interlock tested satisfactorily (6/2/2015).

(4) The seismic displacement & temperature interlocks were tested and found satisfactory on 6/5/2015 and 6/8/2015 respectively.

(5) (a) Control element capsules (cladding) were inspected (6/25/2015) and found to be in good condition with no evidence of deterioration since the previous inspection.

(b) The control rod drive mechanisms were inspected (6/25/2015) and tested with satisfactory results.

(c) Ejection times were measured (6/26/2015) for all SCRAM-able rods, SR-1, SR-2 and CCR and were found to be 0.14, 0.12 and 0.14 seconds respectively. The requirement that the ejection times be less than I second is satisfied.

(d) The reactivity worth of all safety a.nd control rods were measured, as well as the time. required to drive each rod to its fully inserted position. The largest reactivity insertion rate was 0.0241 %Afc/k: s* 1 ($0.0325 s* 1), which is less than the prescribed limit of 0.065%Afc/k: s* 1*

(e) On 8/17/2015 the shutdown margin with both the most reactive SCRAM-able rod and the fine control rod remaining fully inserted was determined to be 1.507%.ilk/k

($2.033) (at the maximum allowable k excess of 0.65 %Afclk:) and satisfies the reci,_uirement that it be greater than 1%Ak/k.

(t) All surveillances were within the appropriate Technical Specification requirements.

C. ~C Inspection The annual inspection was conducted on July 13-16, 2015. No findings of significance

Idaho State University AGN-201M Reactor 2015 Annual Report Page 2of8 were identified. A minor violation was identified for one licensee not performing the functions of Senior Reactor Operator (SRO) for a minimum of a full four hours per calendar quarter.

As of the end of the reporting period, membership of the Reactor Safety Committee (RSC) consisted of the following individuals:

Frank H. Just- Chair (retired from INL)

Mary Lou Dunzik-Gougar - Reactor Administrator George Imel - Assistant Reactor Administrator Adam L. Mallicoat - Reactor Supervisor Richard R. Brey - Dean of College ..

Peter Farina - Radiation Safety Officer Robert Boston, PE, CHP (DOE-ID)

Jay F. Kunze - Former Reactor Administrator

6. Summary of Changes Subject to 10 CFR 50.59 Analyses.

The signal cables for Channels 1, 2* and 3 were upgraded to RG 213 for additional noise reduction.

OP-1 checklist was reproduced to have a digital copy.

7. Radioactive Effluents.

A. Liquid Waste - Total Activity Released: None.

B.

  • Gaseous Waste - Total Estimated Activity Released: 11.3 µCl of Ar-41.

The AGN-201 Reactor was operated for 116.9 watt-hours at power levels up to approximately 4.9 watts. At this power level Ar-41 production is negligible and substantially below the effluent concentration limit given in 10 CFR 20 Appendix B, Table

2. The total activity of Ar-41 released to the environment was conservatively estimated at 11.3 µCi. This activity corresponds to the total activity of all gaseous radioactive effluent from the facility. A monthly summary of calculated gaseous releases is given in Table IV.

8. The latest environmental radiation surveys, performed at the facility boundary while the reactor was operating at 100% of _full licensed po:wer (5.0 watt), measured a maximum combined neutron and gamma dose equivalent rate of 0.43 mrem hr- 1 or less at the outside walls of the building proximal to the reactor. The requirement that the total equivalent dose rate be less than 2.0 mrem hr' 1 was satisfied. .
9. Radiation Exposures.

The Radiation Safety Officer reviews personnel radiation exposures quarterly. Annual reports of ionizing radiation doses are provided by the Radiation Safety Officer to. all monitored personnel as required under the provisions of 10 CFR 19.

Personnel with duties in the reactor laboratory on either a regular or occasional basis have been issued radiation dosimeters by the Idaho State University Technical Safety Office.

The whole body exposures for the 2015 monitoring period of personnel are summarized in TableV:

The doses received for all reactor laboratory personnel during 2014 are well below the dose limits of 10 CFR 20.1201, and well below ISU ALARA limits (1 REM per year, 0.3 REM per quarter).

Anytime a member of the public visits the reactor pin dosimeters are issued for the extent of the tour. A minimum of 1 dosimeter to every 5 people is issued for a representative group dose. During the 2015 calendar year there were 527 recorded visitors to the facility.

A summary of the public dose exposure is presented in Table VI.

Table VI. Summary Whole-Body Exposures to the Public

( 1 January 2015 through 31 December 2015)

Estimated whole-body Number of individuals exposure range (mrem): in each range:

No Observable Dose 518 1.0 mrem* 3 Greater than 1.0 but below 5.0 mrem 5 Greater than 5.0 but below 10.0 mrem 0 Greater than 10.0 but below 15.0 mrem 1*

Total number of individuals reported 527

  • Below 1.0 mrem is considered un-measureable None of the 527 visitors to the facility during 2015 received a measurable dose that would exceed the annual 0.5 rem dose limit of 10 CFR 20.1301. Therefore, the average and

Idaho State University AGN-201M Reactor 2015 Annual Report Page 8 of8 maximum doses received by personnel and the public are well within NRC guidelines.

  • Note there was one reading that was above 5 mrem, this is likely due to the shock of dropping the dosimeter.
