b. Dosimetry was performed using a Victoreen Model 555 -

Integrating dose Rate Meter and Probe. The unit was calibrated on 1-15-71 by the Victoreen Instrument I Company, using cobalt-60 and cesium-13; sources'whose l calibrations are traceable to the U.S. National Bureau I s, .

of Standards. A copy of the calibration certificate

} is available. Backup dosimetry using Harshaw TLD a 6,

devices, and also a modified Fricke chemical system, -

confirmed the Victoreen readings. i; r

c. Flux distribution in Irradiation Chamber (1) At 1 x 105 rad /hr., the flux is described as N a cylinder 50" from the source centerline, O over a vertical height of approximately 45". .;

Assuming a dose rate range of 1.0 to 1.20, the cylinder becomes an annulus with inner radius of 41" and outer radius of 50", with the 1.2 ,

factor at 41". f 1

(2) At 1 x 10 rad per hour, the flux is described -

as a cylinder 15" from the source centerline extending over a vertical height of approximately 53". Assuming a dose rate range of 1.0 to-1.3, J the cylinder becomes an annulus with , inner radius 3

E' SERVICE IRRADIATOR DESCRIPTION C'

4, Irradiations are normally conducted in the hot cell 2-3 complex j (drawing 80004). Product to be processed is placed on a series of turntables arranged in a circular configuration. The source is placed in the center of this arrangement for a preset time.

The source elements are placed in 1/2" diameter 60" long stainless -

tubes, held in a squirrel-cage type holder. Two or three sources are placed in each tube. In the storage position the source holder  ;

is lowered into the water filled pool-to-cell transfer chute to a depth of at least 10 feet, where the surface reading is =cro.

The source is connected by a stainless steel cable to an electrically driven windup drum mounted on a jib crane in the cell. To expose the source, the operator, from the face of the cell, remotely operates the hoist until the source has cleared the storage tube. Using manipulators, he swings the crane into the irradiate position. An I opposite sequence is used to lower the source. In the event of an electrical malfunction, the source can be lowered manually by turning a handle on'a flywheel mounted to the drum with one of the two nearest manipulators. In any malfunction, personnel safety is main-tained as long as the cell remains closed.
