High Range Calibration Unit DESCRIPTION:
The calibrator, CDV-794 Model No.
2, contains a sealed Cesium-137 source that provides four intensity levels for calibrating radiation survey meters.
Inside the calibrator, the radiation source has a fixed position relative to the survey meter in the exposure chamber.
The specific strength of the radiation field in the exposure chamber is controlled through a rotary attenuator.
While a meter is in the radiation field, calibration adjustments are done via remote controls.
Meter readings are observed through the lead-glass window of the chamber door.
The nominal accuracy of the calibrator is maintained by the periodic (approximately every two years) adjustment of a decay compensator.
_The initial radiation intensity of the source is adjusted at the. manufacturer's facility.
The source housing is made of cast depleted uranium.
The housing has three parts: main shield, attenuator disc, and the collimator.
The source is composed of Cesium-137 chloride pellet that is doubly encapsulated in 316 stainless steel and sealed by welding.
The Model ORNL-2339A source had been replaced by a new source model ORNL-DSK-2384.
The new source had been tested and meets Special Form testing requirements.
The entire source housing consisting of the exposure chamber and electronics assembly are placed in a lockable metal cabinet.
DIAGRAM 1 See attachments 1 and 2.
LABELING:
The unit is labeled in accordance with 10 CFR 20.1901 and 10 CFR 20.1904.

SAFETY EVALUATION OF DEVICE.
NO.: NR-8095-D-806-S DATE.
OCT 0 719mr PAGE 3 OF 5 DEVICE TYPE:
High Range Calibration Unit i
f0NDITIONS OF NORMAL USE:
The device will be used in a laboratory environment by trained personnel to remotely calibrate high range CDV survey meters.
PROTOTYPE TESTING:
1 The sealed source Model ORNL-233 9A had previously been deemed acceptable by the NRC.
The sealed source Model ORNL DSK-2384 had been tested and achieved DOT special form requirements.
- Also, the source achieved an ANSI N542 of 77E43525.
The device manufacturer performed the following tests on the device:
- Operational Test
- Radiation Field Test
- Temperature Test at -3 0 *F to 12 5 F (-34.4'C to 51. 7'C)
- Humidity Test
- Shock Test EXTERNAL RADIATION LEVELS:
1 The device manufacturer had reported that dose rates up to 400 R/hr (4 Sv/hr) are obtained within the chamber.
t Additionally, the device was designed so that radiation dose L
rates at every accessible surface of the unit, with the exception of the beam path, do not exceed 2 mR/hr (20 pSv/hr).
]
OUALITY ASSURANCE AND CONTROL:
The manufacturer and distributor had previously submitted a program that was deemed acceptable by the NRC.

High Range Calibration Unit LIMITATIONS AND/OR OTHER CONSIDERATIONS OF USE:
The device shall be used by persons specifically licensed by e
the NRC or an Agreement State.
These devices will no longer be commercially distributed but may still be approved for licensing purposes.
Handling, storage, use, transfer, and disposal: To be determined by the licensing authority.
In view that these sources exhibit high surface dose rates when unshielded, the sealed sources should be handled only by experienced licensed personnel using adequate remote handling equipment and procedures.
The sealed source shall be leak tested at intervals not to exceed 6 months using techniques capable of detecting 0.005 microcurie (185 Bq) or removable contamination.
- This registration sheet and the information contained within the references shall not be changed without the written consent of the NRC.
SAFETY ANALYSIS
SUMMARY
Based on our review of the information and test data cited below, that the device was previously deemed acceptable for licensing by the NRC in the 1960's, and that the new replacement source improves the containment of Cesium-137 chloride pellets, we continue to conclude the CDV-794 Model 2 calibration design is acceptable for licensing purposes.
Furthermore, we continue to conclude that the devices would be expected to maintain their containment integrity for normal conditions of use and accidental conditions which might occur during uses specified in this certificate.

Dear Mr. Baggett,
The Director of the Federal Emergency Management Agency (FEMA) made the decision to close the National Instrumentation Center (NIC) at the Mt. Weather Emergency Assistance Center (MWEAC), Bluemont, 1996.
Virginia, effective August 15, 2 are in Radioactive Sources in the possession of FEMA at +hn temporary storage, awaiting either the transfer s) a properly licensed recipient or disposed of as radioactive was;u.
radioactive sources owned by The licensed recipient who possess or dispose of FEMA will either retain possession of the sources, them as radioactive waste.
it is requested that the following Due to the closure of the NIC, registry numbers in our License be given inactive status:

NR-283-D-105-S to?

NR-283-D-80i-S NR-283-D-802-S NR-283-D-803-S It is anticipated that the annual fees for the devices covered by each registry number will be frozen for FY 1998.
We are currently in the process of reconciling and updating our computerized inventory Radioactive Materials (RAM) Data-Base to reflect what we currently own and possess and what radioactive material and devices have been transferred to licensed recipients or disposed of as radioactive waste.
When completed, we will provide you with an updated inventory.
