• Electrical transients are signal & power irregularities associated with using older vacuum tube based analogue circuitry.

4. Safety-Related Corrective Maintenance:

1/31/2012: Channel 3 detector changed its response output and was replaced with a comparable BF3 tube. In addition the SHV connector was replaced with one designed for RG-59 cable and recalibrated.

3/6/2012: The down indicator switch on the FCR had been knocked out of place, causing the drive to continue to drive out despite being in the bottom position and the interlock OK light bulb failed. The switch was repositioned for proper operation and the light bulb replaced.

3/14/2013: A bad cable connection causing a short, preventing the magnet to energize, was located.

A bypass cable fixed the problem and the main cable connection fixed to return normal functionality.

3/21/2012: The Channel 3 detector lost signal, a connection problem was the likely cause. The detector chamber was removed and all connecting cables were replaced with new connections, returning functionality to the system.

5/25/2012:The rod drop box was rebuilt with new wiring after a significant amount of troubleshooting.

5/30/2012: A power outage cause damage to Channel 2. Vacuum tubes V-12, V-14 & V-17, power line fuse, and the 1.5-volt battery were replaced.

Idaho State University AGN-201M Reactor 2011 Annual Report Page 7 of 10 6/5/2012: Magnet current was found to be high (0.9 mA) and after replacing the V-7 vacuum tube the current returned to a normal 0.6 mA.

8/30/2012: Channel I was having signal problems due to improper cabling and connectors. The system was rebuilt in a way so that the detector's position does not stress the signal cable and removes the need to raise the detector.

10/4/12: The analogue position display primary gear broke so that the tens digit wouldn't turn.

The unit was replaced with a comparable spare.

12/3/12: Channel 2 failed pre-start checks. The F-I (250V 3A) fuse, V-13 6Y6GA vacuum tube, V-12 6BW4 vacuum tube, and the V-I 6BW4 vacuum tube was replaced in Channel 2 to return functionality.

12/12/12: During operation the Safety Rod I dropped out properly, however the chassis jammed in position. It was found that the twin drive screws were uneven; they were greased and reset into position. In addition there was a problem with the "Lp" microswitch; the microswitch and the wiring were replaced.

5. Modifications.

A. Changes in Facility Design.

None.

B. Changes to Procedures.

None.

C. Experiments.

Experimental procedure 12 Oscillator Experiment was revised to have descriptions for both linear and rotary oscillators and guidelines for operating them simultaneously.

D. Reactor Safety Committee.

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 fromn FIN.)

Jay F. Kunze - Reactor Administrator Adam L. Mallicoat - Reactor Supervisor Richard R. Brey - Department Chair Peter Farina - Radiation Safety Officer Robert Boston. PE, CHP (DOE-ID)

Kermit Bunde (DOE-ID)

Idaho State University AGN-201M Reactor 2011 Annual Report Page 8 of 10 Richard E. McCracken (retired from INL)

6. Summary of Changes Reportable under 10 CFR 50.59.

The paper chart recorder set up for the detector channels 2 & 3 were changed to utilize a digital chart recorder. The new recorder is capable recording data and displaying the response over time and cannot impact reactor operation as installed. The data is stored on a removable flash drive for easy analysis and storage.

7. Radioactive Effluents.

A. Liquid Waste - Total Activity Released: None.

B. Gaseous Waste - Total Estimated Activity Released: 14.4 ýtCi ofAr-41.

The AGN-201 Reactor was operated for 148 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 14.4 i.Ci. 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.

Idaho State University AGN-201M Reactor 2012 Amiual Report Page 9 of 10 8, The latest environmental radiation surveys, performed at the facility boundary while the reactor was operating at 60% of full licensed power (3.0 watt), measured a maximum combined neutron and gamma dose equivalent rate of less than 2.0 mrem hr' at the outside walls of the building proximal to the reactor. The total equivalent dose rate at 100% power at these locations was less than 4 mrem hr".

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 duty category and whole body exposure for the 2012 monitoring period of personnel are summarized in Table V:

The doses received for all reactor laboratory personnel during 2012 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 I dosimeter to every 5 people is issued for a representative group dose. During the 2012 calendar year there were 476 recorded visitors to the facility.

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

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

No Observable Dose 433 1.0 mrem* 30 Greater than 1.0 but below 5.0 mrem 12 Greater than 5.0 but below 10.0 mrem 1 Total number of individuals reported 476

• Below 1.0 mrem is considered un-measureable None of the 476 visitors to the facility during 2012 received a measurable dose that would exceed the annual 0.5 remn dose limit of 10 CFR 20.1301. Note there was only one reading that was above 5 mrem, this is likely due to the shock of dropping the dosimeter.

Therefore, the average and maximum doses received by personnel and the public are well within NRC guidelines.

• Electrical transients are signal & power irregularities associated with using older vacuum robe based analogue circuitry.

4. Safety-Related Corrective Maintenance:

1/31/2012: Channel 3 detector changed its response output and was replaced with a comparable BF3 tube. In addition the SHV connector was replaced with one designed for RG-59 cable and recalibrated.

3/6/2012: The down indicator switch on the FCR had been knocked out of place, causing the drive to continue to drive out despite being in the bottom position and the interlock OK light bulb failed. The switch was repositioned for proper operation and the light bulb replaced.

3/14/2013: A bad cable connection causing a short, preventing the magnet to energize, was located.

A bypass cable fixed the problem and the main cable connection fixed to return normal functionality.

3/21/2012: The Channel 3 detector lost signal, a connection problem was the likely cause. The detector chamber was removed and all connecting cables were replaced with new connections, returning functionality to the system.

5/25/2012:The rod drop box was rebuilt with new wiring after a significant amount of troubleshooting.

5/30/2012: A power outage cause damage to Channel 2. Vacuum tubes V-12, V-14 & V-17. power line fuse, and the 1.5-volt battery were replaced.

Idaho State University AGN-201M Reactor 2011 Annual Report Page 7 of 10 6/5/2012: Magnet current was found to be high (0.9 mA) and after replacing the V-7 vacuum tube the current returned to a normal 0.6 mA.

8/30/2012: Channel I was having signal problems due to improper cabling and connectors. The system was rebuilt in a way so that the detector's position does not stress the signal cable and removes the need to raise the detector.

10/4/12: The analogue position display primary gear broke so that the tens digit wouldn't turn.

The unit was replaced with a comparable spare.

12/3/12: Channel 2 failed pre-start checks. The F-I (250V 3A) fuse, V-13 6Y6GA vacuum tube, V-12 6BW4 vacuum tube, and the V-I 6BW4 vacuum tube was replaced in Channel 2 to return functionality.

12/12/12: During operation the Safety Rod I dropped out properly, however the chassis jammed in position. It was found that the twin drive screws were uneven; they were greased and reset into position. In addition there was a problem with the "up" microswitch; the microswitch and the wiring were replaced.

5. Modifications.

A. Changes in Facility Design.

None.

B. Changes to Procedures.

None.

C. Experiments.

Experimental procedure 12 Oscillator Experiment was revised to have descriptions for both linear and rotary oscillators and guidelines for operating them simultaneously.

D. Reactor Safety Committee.

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

Frank Fl. Just - Chair (retired from INL)

Jay F. Kunze - Reactor Administrator Adam L. Mallicoat - Reactor Supervisor Richard R. Brey - Department Chair Peter Farina - Radiation Safety Officer Robert Boston, PE, CHP (DOE-ID)

Kermit Bunde (DOE-ID)

Idaho State University AGN-201M Reactor 2011 Annual Report Page 8 of 10 Richard E. McCracken (retired from INL)

6. Summary of Changes Reportable under 10 CFR 50.59.

The paper chart recorder set up for the detector channels 2 & 3 were changed to utilize a digital chart recorder. The new recorder is capable recording data and displaying the response over time and cannot impact reactor operation as installed. The data is stored on a removable flash drive for easy analysis and storage.

7. Radioactive Effluents.

A. Liquid Waste - Total Activity Released: None.

B. Gaseous Waste -Total Estimated Activity Released: 14.4 1.tCi of Ar-41.

The AGN-201 Reactor was operated for 148 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 14.4 [tCi. 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.

Table IV. Summary of Monthly Gaseous Radioactive Effluent Releases (1 January 2012 through 31 December 2012)

Ar-41 Month (vCi)

January 0.0 February 1.0 March 1.2 April 1.7 May 0.8 June 0.8 June 0.6 August 1.4 September 3.0 October 1.5 November 1.7 December 0.6 Total 14.4 C. Solid Waste - Total Activity: None.

8. The latest environmental radiation surveys, performed at the facility boundary while the reactor was operating at 60% of full licensed power (3.0 watt), measured a maximum combined neutron and gamma dose equivalent rate of less than 2.0 mrem hr-' at the outside walls of the building proximal to the reactor. The total equivalent dose rate at 100% power at these locations was less than 4 mrrem hr 1 .

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 duty category and whole body exposure for the 2012 monitoring period of personnel are summarized in Table V:

The doses received for all reactor laboratory personnel during 2012 are well below the dose limits of 10 CFR 20.1201, and well below ISU ALARA limits (I 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 I dosimeter to every 5 people is issued for a representative group dose. During the 2012 calendar year there were 476 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 2012 through 31 December 2012)

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

No Observable Dose 433 1.0 mrem* 30 Greater than 1.0 but below 5.0 mrem 12 Greater than 5.0 but below 10.0 mrem 1 Total number of individuals reported 476

• Below 1.0 mrem is considered un-measureable None of the 476 visitors to the facility during 2012 received a measurable dose that would exceed the annual 0.5 rem dose limit of 10 CFR 20.1301. Note there was only one reading that was above 5 n-rem, this is likely due to the shock of dropping the dosimeter.

Therefore, the average and maximum doses received by personnel and the public are well within NRC guidelines.
