2. HISTORY ((,, The HFIR Project was engaged in the manufacture of research reactor fuel elements. The HFIR Project facility was located in Building 10 at the Attleboro, Massachusetts site of Texas Instruments, Inc. Manufacturing operations included blending and compacting SNM as enriched U 03 8 and aluminum powders, hot roll-bonding compacts into aluminum-clad fuel plates, assembling fuel plates into fuel elements. All SNM associated with the HFIR Project, from receipt and storage through processing and packaging for shipment, was confined to the HFIR facility, the Metallographic Laboratory and the Chemical Laboratory. All processing of unclad SNM was performed in the Fuel Manufacturing Area (FMA) in dry boxes or hoods with ventilation conforming to NRC requirements. The FMA was separated by partitions from the surrounding General Manufacturing Area (GMA). Also, the FMA was maintained at a negative pressure relative to the surrounding GMA. No exposed or unclad SNM was processed in the GMA. Completed fuel elements and fuel plates and scrap containing U03 8 were removad from the facility by the USA Department of Energy. Contaminated waste was sent to an NRC licensed facility for burial. gO No chemical or recovery operations were. performed on the \\_/ SNM during manufacturing processing. 4 a 3. O m
3. PROCEDURE \\ Decommissioning & Decontamination The HFIR Project had two areas for decommissioning. General Manufacturing Area: All equipment, tools, materials and supplies were cleaned and surveyed for radioactivity and released to Babcock & Wilcox (an NRC licensee) who removed them from the project to their Lynchburg, VA facility. All partitions, extraneous water, and gas, air and steam piping and electrical services were surveyed for radioactivity and released for unconditional removal and disposal. These items and area were never exposed to unclad SNM during the operation of the HFIR Project. For the most part, the HFIR Project general manufacturing area did not have preliminary measurements of surface radio-activity that exceeded one third the NRC unconditional release limits. Nevertheless, the ceiling, walle, partitions and pipes and ducts remaining after decommissioning were cleaned with a steam jet and a decontaminating solution (Turco #4324) before measurements were taken for the " Request for Termination" report. The concrete floor was washed with water and a decontaminating [~ ) solution (Turco# 4324) prior to measuring of surface radioactivity. \\m / Limited areas of the floor that had measurements that exceeded one third the NRC unconditional release limits were either rewashed with water and the decontaminating solution, and/or the top surface of the floor was scarified by removing approximately 265 grams of concrete per sq. ft. In all cases, the rewashing and/or scarifying operation reduced the measurements of radioactivity to substantially less than one. third the NRC unconditional release limits. The removed concrete was collected and placed in containers for burial at a licensed burial site. Two areas of the GMA floor that were not typical were a service trench and a machine foundation. For the trench, floor plates were removed and cleaned and the supports were cleaned with water and the decontaminating solution and with wire brushing as necessary. The trench was located at coordinates 1 thru 18,27. The machine foundation was completely uncovered by removing a floor patch and all fill. All surfaces of the foundation were then cleaned by washing with water and the decontaminating colution with wire brushing, chipping or scarifying as necessary. The machine foundation was located at coordinates 3 thru 7, 70 thru 74. The Fuel Manufacturing Area: All equipment and tools were cleaned and released to Babcock & g-'S Wilcox (B&W) (an NRC licensee). B&W then removed them from the ( '; project to their Lynchburg, VA facility as low specific activity (LSA) by exclusive use transport. 4.
3. PROCEDURE (con't) ~s All partitions, extraneous water, gas, air and steam piping and electrical services were removed and packaged and sent to Chem-Nuclear, Barnwell SC (an NRC licensee) for burial. These actions disposed by removal and burial, items that had the possibility of being contaminated by SNM during the operation of the HFIR project. The HFIR project fuel manufacturing area floor, ceiling, columns and pipes and ducts remaining after decontamination were cleaned with a steam jet and a decontaminating solution (Turco# 4324). The floor was then scarified by removing approximately 265 grams of concrete per sq. ft. Portions of the floor that indicated floor patches over previous machine foundations were identified and the patches and any fill removed. The uncovered concrete was then washed with water and a decontaminating solution. (Turco #4324 ) Electrical supply bus ducts were covered during steaming operations, and the covering removed in local areas for sampling. No cleaning prior to measuring for radioactivity was performed in the Metallagraphic and Chemical Laboratories, as no SNM has been present in these laboratories for over 5 years and there had been prior cleaning and release programs. -s \\2 No cleaning prior to measuring for radioactivity was performed on the roof of Building 10 as the regular monitoring of the two exhausts from the fuel manufacturing area have always showed essentially background radioactivity in the air being discharged. i OV s.
MEASURING PROCEDURE p Direct a and S/y The instruments used for the direct a and S/y radioactivity measurements were portable type with digital read out. Instrument calibration and checks were performed according to NRC license requirements. A typical calibration procedure, a calibration sticker and the dates of instrument calibration are shown in Appendix B, 5.1 Radiation Instruments Calibration Procedure, 5.2 Radiation Instruments Calibration Sticker, 5.3 Radiation Instruments Calibration Dates. Background measurements were taken in the vicinity of the associated selected measurement locations with a frequency of one background reading for every five measurements. All other measuring techniques were performed in accordance with NRC license requirements. All measurements were taken for a duration of one minute minimum. All measurements were corrected for the efficiency of the instruments. All selected locations on the floor, ceiling, walls and columns were measured for direct a and S/y racioactivity. s Removable a Discs of Whatman #41 paper were used for wiping the specified surfaces for removable radioactivity. Up to 90 discs were each counted for 5 minutes along with two background readings and two measurements of the radioactivity of a standard source. All other measurement techniques were performed in accordance with NRC license requirements. Measurements for removable a radioactivity were made when the m<2asurement of direct a radioactivity exceeded approximately one third of the release limits for removable a radioactivity. By this means, either measurements for direct a radioactivity or measurements for removable a radioactivity provide assurance that removable a radioactivity limits are met. Location of Measurements and Reporting of Results General Manufacturing Area (GMA) as Shown in Figure 1.

Up to 4 x 4 blocks of one square meter areas were designated as a sample area. -s \\_/ 6.
FLOORS (con't) (\\_ For each 4 x 4 block in a sample area, two square-meter areas were selected on a random basis. Five measurement locations were chosen within the selected square meter areas on a random basis. The five measurement locations were identified by grid coordinates within the selected square-meter area. The average result for each selected square-meter area was calculated using the five measurements for that area. The final highest individual measurement and the average for each chosen square meter area along with the original highest measurement and average are shown in Appendix A 4.1.5 (Surface). Any coating was removed from the floor in each of the six-teen square meter areas in a sample area to give a weight of approximately 1/2 grams of coating for each area. The sixteen samples of coating were combined and the composite sample analyzed for uranium. The results of the analysis represented that particular 4 x 4 sample area of floor. All analysis results are shown in Appendix A 4.1.5 (Coating). Approximately one in a group of four or five floor bolts were removed from the floor and the bolt measured for radioactivity.

A MODEL 2100 - SCALER RATEMETER July 1, 1980 Calibration Procedure Pace 1 GENERAL: ( .q % 1 () The Model 2100 provides all electronic circuitry required for scintillation, proportional, or GM detectors. The unit may be operated from four flashlight batteries or line power. PREPARING FOR OPERATION: BATTERY OPERATION: 1. Slide battery lid knob down, open lid (at rear of instrument) and place four "D". cells in instrument; two in, two out. Note polarity on battery door. 2. Turn power switch to BAT. Press red BAT button to test batteries. A down scale reading indicates batteries in backward. 3. Read detector operating point section to set up detector. RECHARGEABLE BATTERY OPERATION: 1. Place batteries in instrument as noted above. Turn power switch to BAT. Press BAT test button to insure batteries are installed with proper polarity. 2. Connect instrument to line power. Turn selector switch to CHG. Allow batteries to charge 24 hours (or longer if desired). m 3. Upon completion of the charge, turn power switch to BAT and proceed. LINE OPERATION: Connect instrument to line power of 115 volts 50'-60 Hz. Turn power switch to LINE and proceed to use the instrument. NOTE: With the instrument on line power, a small trickle charge is connected to the battery pack to maintain a high state of charge. NOTE ON BATTERY LIFE: Battery life is a function of lamp illumination level and H.V. Power supply load-ing. With all digits on 888888, maximum brightness and the power supply set at 1000 volts, four new Ray-0-Vac "C" cells purchased at a local supermarket ex-hibited a useful battery life of 2 hours. With the instrument off for 4 hours, the batteries recovered enough for some additional usage. Under the same conditions as above, only with the dimmer control set for "just barely readable" 20 hours of battery life can be obtained. Turning the lamps off except when reading will result in significant increase in battery life to an excess of 50 hours. q For normal operation, with the lamps at half brightness and reasonable discipline in keeping a minimum number of digits on, battery life of 20 - 30 hours can be V) realized. 104.

Select either line or battery operation with power switch. 2. Press COUNT, press HOLD. (This resets and stops the scaler) 3. Turn DISCR clockwise, back off 1/4 turn. OPERATING POINT: Instrument and detector operating point is established by setting the probe y voltage (HV) and instrument sensitivity (Discriminator). For a given de-tector system, ef ficiency, back ;r eund and noise are fixed by the physical nake-up of the detector and rcerly vary from unit to unit. However, the selection of the operating point makes a marked difference in the apparent contribution of these three sources of count. In the singular case of the GM detector, a minimum operating voltage is re-quired to establish the GM operating region. (At lower voltages, the detector operates as a very insensitive proportional counter). This detector is not capable of energy discrimination (pulse height discrimination). For gain sensitive detectors (proportional or scintillation), the most straightforward method of selecting the operating point is to develop a graph relating count rate to system gain. This relationship is commonly re-ferred to as a plateau or instrument plateau curve. System gain may be changed' gs by adjusting detector high voltage, or discriminator. LIMITATION OF CONTROLS: H.V. Control: The high voltage control provides a linear adjustment of the detector voltage supply. The range is approximately 200 to 240J volts thru the full po'tentiometer. Changing the detector voltage will cause the detector gain to change. It should be remembered that a linear change in voltage will cause an exponential change in detector gain. DISCRIMINATOR: The gain control is a non-indicating control, allowing a wide selection of operating point without exceeding the linear ranges of the amplifier. Maximum amplifier sensitivity occurs at maximum clockwise setting. For proportional and scintillation detectors, set this control fully clockwise. For GM detectors, set this control counter clockwise to insure that the 2100 does not double pulse. Check this by observing the scaler while counting at a very low rate. The scaler count will advance by two counts per pulse in the double pulse region. DETERMING INSTRUMENT PLATEAU AND SELECTING OPERATING POINT: 1. Set X0.1-X1 to X0.1 and Minutes to 01. This gives a 1/10 minute count. 2. Set DISCR as indicated before. v 105. W G

With detect.or shielded from source, turn up high voltage control in relativ'ely large increments (1/2 turn at a time), and take a plot of IIV position versus count rate until the detector voltage rating (or obvious breakdown) is reached.

Plot both sets of data and select the operating point to correspond with maximum source count and minimum background count. Always try for center of " plateau" setting and avoid areas of very fast count rate changes with small changes in detector voltage. 6. Record H.V. control setting, or check and record 11. V. meter setting. CALIBRATION COUNT RATE METER: "annect instrument to a pulser. Set time to 1.0 minute and count incoming 7-guise rate in the, range of 300 to 450 counts per minute. Set range switch ( l to 1 and adjust subsurface control labeled "1" so that rate meter corresponds -? - to scaler reading. Repeat for each scale. CLOCK: Refer to clock board section. NOTE: This instrument is supplied with a charge sensitive preamplifier. In that most pulsers have. a variation in output impedance with changes in pulse height, place a 10,000 ohm resistor in series with the pulser output. This will' convert the pulser-from a voltage output to a current output and will allow linear operation with the Model 2100. e 106. s
