Armed Forces Radiobiology Research Institute Reactor Facility Annual Report 1 Oct 1984 to 30 Dec 1984 htroduction 1his is a supplemental report issued to cover the time period 1 Oct 1984 to 30 Dec

- 1984. We shortened period reflects the change necessary to comply with a change in reporting period required of the new AFRRI technical specifications issued

1 Aug 1984. 'Ihis report when attached-to 'the report submitted 30 Sept 1984, becomes the CY 1984 Annua 1 report in its entirety.

Ihis report is written in a format to include notification items required by the technical specifications. Items ' not specifically required but of a general information value will be given in the General Information section. Each section following the general information corresponds to the required section as listed in Section 6.6.la of the AFRRI technical specifications.

4 General Information 1.' Current key AFRRI personnel are as follows Director - COL Bobby R. Adcock, MS, USA Deputy Director - CDR Richard I. Walker, MSC, USN Chairman, Radiation Sciences Dept. - CDR Vincent L. McManaman, MSC,USN

'Calef, Radiations Sources Division - CPT IAonard A. Alt, EN, USA '

3. 'There were no personnel departures during this period.

4. Were were no changes in the RRFSC this period.

- Section I CHANGES 'tT) DESIGN, CHARACTERISTICS, PROCEDURES, AND THE RESULTS OF SURVEELLANCE TESTING

a. Were were no changes to design, characteristics, or procedures as given in the SAR this period. A current startup and shutdown checklist are enclosed for information.

b. All surveillance items were accomplished on time. Malfunctions discovered are included in Section IV.

Section II ENERGY GENERATED ON CURRENT CORE Month Kwh Oct 8810.4 Nov 5998.0 Dec 6502.6 Total power - 486348.3 Kwh Total pulses greater than $2.00 - 3556 L

Section III UNSCHEDULED SHUTDOWNS Were were no unscheduled shutdowns in this reporting period. Unscheduled maintenance is listed in Section IV.

Section IV SAFETY CORRECTIVE MAINTENANCE We following are malfunctions that occurred to reactor equipment during this reporting period. We reason for the corrective action taken, in all cases, was to return tne failed unit to its proper operational status.

13 Nov 84_ During a startup checklist the linear count rate section of the linear channel failed to respond on serial ranges. We linear count rate board was replaced with a calibrated, fu111y functional board. We old

- board was checked,' repaired and found functional.

26 Nov 84 Gas stack monitor found to be inoperative due to loss of counting gas.

Oas tank replaced with full tank, lines purged, system operational.

10 Dec 84 Loss of signal on linear count rate section .003w to 300w. Replaced amplifier on board XH211. Channel recalibrated, system returned to service.

12 Dec 84 Magnet "on" light bulb not making good contact, causing safe rod to drop. Bulb contacts cleaned, bulb replaced, system tested found fully operational.

Section V FACILITY CHANGES Were were no changes to the facility this period.

Section VI

SUMMARY

OF SAFETY EVALUATION CHANGES NOT SUBMITTED TO NRC PURSUAKT'tO 10 CFR 50.59 Were were no changes, new tests, or experiments this period.

Section VII

SUMMARY

OF RADIOAC'IYVE EFFLUENTS RELEASED a.- - Liquid waste - %e estimated average release on a quarterly basis is for the quarter less than 25% of the allowable release.

b. . Gaseous Waste - Dere was no particulate discharge in the last quarter CY 1984. We total Argon 41 discharged 1 Oct - 31 Dec is 8.3 Cf.

c. Solid Waste - All solid material was transferred to the AFRRI byproduct license, none was disposed of under R-84.

Section VIII ENVIRONMENTAL RADIOLOGICAL SURVEYS

a. We results of environmental sampling of soll, water and plant growth were not demonstrably above the normal range of background levels. We radionuclides found were those normally expected in natural background radioactivity and from longterm fallout.

b. Results of the environmental dosimetry program showed the following for the calendar year 1984:

1. We average background was determined to be 81.9 +/- 5.5 mrem.

2. De average reading above background was determined to be 7.0

+/- 2.5 mrem.

3. De highest station reading was determined to be 34.1 +/-20.5 mrem.

4. De results above are expressed at a 95% confidence level,

c. R1 plant surveys, including effluent filters analysis, showed no measurable activity (unless specified in VII above).

d. Dere were no special environmental studies.

Section IX EKPOSURES GREATER THAN 25% OF 10CFR20 There were no visitors to, or staff members of, the reactor facility that received greater than 25% of the allowable dose given in 10CFR20 this reporting
