'1. 0 RADIOGRAPHIC TACILITY l

1.1 Material of Radiation. Cell 1.1.1 The floor of the radiation cell is constructed of a concrete slab. The area above the cell is covered by mason board type material and corrugated metal.

)

The roof area immediately above the celle is a "High i

Radiation" area with a " Radiation Area" at its e

perimeters.

This radiation area is surrounded by an anti-personnel fence with a locked gate and i

appropriate warning signs.- The key to the gate will be controlled by the R.S.O.

The radiation levels outside this " Radiation" area shall not exceed two 1

millirems in any one hour, nor 100 millirems in seven consecutive days. The walls of the radiation l

cell are as called out on drawing (Appendix 1) and shows the respective radiation levels.

1.2 Security Safeguards 1.2.1 A Tech / Ops Model 492D " Gamma Alarm" is installed in-the radiation cell.

The " Gamma Alarm" emits a flashing high intensity red light when 1 mR/hr. is present.

If the door is opened or left open, a loud audible alarm will sound. Audible alarm will dis-continue when door is closed. Personnel ore warned to keep out of area when red light is present.

(When no radiation is present, a green light in on.)

The " Gamma Alarm" is checked for proper operation when quarterly inventory of source is taken.

2.0 RADIATION DETECTION INSTRUMENTS 2.1 The Niles Steel Tank Company uses three survey meters, two pocket dosimeters and one dosimeter charger of radiographic functions performed; they are as follows:

INSPECTION AND MAINTENANCE PROCEDURES 7

9.0L EQUIPMENT: Tech / Ops Model 402 6 660 Camma Ray Projector' A)

To insure safety in use and to avoid malfunctions that i

could impair.the productivity of-this equipment, the following inspections are to be made. Missing or defec-tive components must be replaced or repaired,1f the equip-ment is to function as designed.

9.1 Daily Inspection A) The daily checklist is shown on form NST/Rl.

B)

Each item on this checklist is to be performed daily

~

and be recorded by the radiographer.

(But only if

'l projector 1,s being used.)'

9.2 Periodic Inspection and Maintenance A) This inspection shall be conducted on a quarterly basis-as outlined in the following paral.caphs.

T 9.2.1 Equipment and Material A)

Source changer - wrenches - screwdriver and allen-keys - basin approximately 12" diameter - two (2) quarts solvent (perchlorethylene) - syringe -

lubricant (2 oz.' Texaco "Unitemp" grease) - dummy source assembly, 9.2.2 Procedure t

A)

Remove the source from the unit and store it in the source changer. Follow the instructions for the use of the source changer.

9.2.3 Control A) After the sourcs has been removed from the projector, eject and coil the source drive cable by cranking -

i the control in EXPOSE direction. Examine cable for kinks, fraying, broken wires, or rust. Minor bends in the cable may be straightened by hand. DO NOT, USE PLIERS. A cable with frayed or broken wires j

h.

must be replaced.

Light rust may be removed by HAND wire brushing. Do not use a powered brush or abrasives. Heavy rust that has penetrated into the' cable will cause unsatisfactory operation or failures.

Replace cable.

navises 1u-10-31 me x

B) Clean the cable by immersingLthe coil in solvent.

A heavy accumulation of dirt-ladden lubricant may require more:than one washing.

l C): Examine the' connector. Use the Tech / Ops Model 550 connector gage to check for wear.

Replace-if con-nector fails at any gaged dimension.

Examine cable attachment to connector:for straightnass and evid-ence of~ looseness. A loose' attachment or bend at-this point must be repaired.- Do not attempt to fcbricate a replacement connecter or.to fasten one to the cable. The connector is a special heat treated stoel made to exacting tolerances and under

-strict metallurgical centrol. _The attachment is swaged with special tools and proof tested.

Order a replacement from Technical Operations Inc.-

D) Lubricate'the cable with Texaco "Unitemp" s'rease.

This is the most satisfactory 1ubricant for this

. purpose.

Common greases can dause gumming and unsatisfactory operation. Take care in handling the cable to avoid picking up dirt or grit.

9.2.4.LControl. Crank A) Remove control cable housings by undoing fitting nuts.

Remove crank unit from reel, remove crank-

,and disassemble. Wash parts in solvent.. Check I

inside of housing for evidence of galling.and wear.

A deeply scored (more than.020 deep) line shere

~

c the cable contracts the inner wall'of the housing indicates the need for replacement.

B) check clearance between the hubs of the wheel and tho' bushings. More than.005 clearance indicates need fcr replacenest.

C)- Examine teeth of wheel for damage. A bent tooth may be filed off. Two or more bent teeth-adjacent will require replacement of the wheel.

D) Lubricate bushings with'"Unitemp" grease and reas-(
