OPER ATHIG & EMERGENCY PROCEDURE
/
necessiona ORIGINAL DATE: June 29,1987 PAGE 1 of 15 1.0 SCOPE l.1 In conformance with 10 CFR part 34, Professional Welding Associates has developed this program of operating and emergency procedures. These procedures will provide radiography personnel with a guide for consistent performance end documentation of radiographic operations. Each radiographer and radiographer's assistent will be issued a copy of these procedures which shall be at their disposal at all times during radiographic operettoris.
2.0 DEFINITIONS 2.1 The following terms commonly used in this procedure are O
cerined as roiiows:
RSO - Radiation Safety Of ficer.
NRC - United States Nuclear Regulatory Commission.
Radiographer - any individual who performs or who, in ettendence et the site where sealed sources are being used, personally supervises radiographic operations and who is responsible for assuring compliance with this program and the applicable NRC requirements.
Radiographer's Assistent - any individual who, under the personal supervision of a radiographer, uses redtographic exposure devices, sealed sources, related handling equipment, or radiation survey instruments in the performance of radiography.
Radiographic Exposure Device - Any instrument containing a sealed source fastened to or contained therein.
)
OPER ATHIG &. EMERGEllCY PROCEDURE no,.e,s e ORIGINAL DATE: June 29,1987 PAGE 2 of 15 Radiography -The examination of the structure of materials by nondestructive methods utilizing sealed sources.
Restricted Area - Any crea access to which is controlled for, purposes of protection of individuals from exposure to radiation and radioactive materials.
Sealed Sources - any by product material that is encased in a capsule designed to prevent leekoge or escape of the by product meterial.
Storage Area - Any location, f acility, or vehicle which is used to store, transport, or secure a radiographic exposure device, storage container, or sealed source when it is not in use and
( )
which is locked or has a physical barrier to prevent accidental exposure, tempering with, or removal by unauthorized personnel.
Storage Container - A device in which exposure devices are stored or transported.
Source Changer - A device designed and used for replacement of sealed sources in radiographic exposure devices.
3.0 PRINCIPLES OF RADI ATION SAFETY 3.1 Industrial radiogrophy operations require the use of radiation sources having high energy and high emissivity. Unless these radiation safety precautions are understood and utilized, there is the possibility of overexposure. The information contained in these paragraphs contains the three basic principles for controlling personnel exposure which are (1) Time,(2) Distance (3) and Shielding.

i y
OPERI.THIG & EMERGEleCY PROCEDURE tj noresnotw, ORIGINAL DATE: June 29,1987 PAGE 3 of 15 3.1.1 Time - Personal dosage depends directly upon the time a person remains in o radiation field. An individual that s
would receive only 3 mR in 2 minutes et a given point, would receive 15 mR if he remained there for 10 minutes.
Limiting the working time in a radiation field requires the conscientious use of survey instruments.
3.1.2 Distance - Lower personal exposure will be received at greater distances. Simply, the greater the distance the lower the exposure.
3.1.3 Shielding - in the event that working time is too long or operating conditions prevent on adequate exposure distance, shielding, such as a collimotor, may be placed between the source and personnel. Shielding will not stop all the (3
radiation but it con reduce the intensity to a level that will V'
permit performance of radiography without excessive exposure to personnel.
4.0 LIMITS OF RADI ATION EXPOSURE 4.1
-In accordance with 10 CFR part 20, Professional Welding Associates Inc. has set limits on individual radiation exposure.
Except as otherwise provided in paragraph 4.2, no individual working in a restricted crea shall receive in any calendar quarter a total occupational dose in excess of:
REMS PER CALENDER QUARTER

DUARTERLY MAINTENANCE AND INSPECTION 1.0PROCEDUR_E 1.1 Radiography equipment will receive a general maintenance and inspection every 90 days. If any part of the source assembly (pigtail) should need repair, do not attempt to do so in the field.
If a source assembly should need repair notify the RSO. The quarterly maintenance procedure is as follows:
1.)
Remove the safety cap and inspect the source connector.
(
)
The connector should not be damaged or show signs of excessive wear. Check the connector for straightness at the flexible cable. If the connector is satisf actory, the mating connector should be connected to the source and about 30 to 40 pounds of pressure should be applied. If connector is damaged or inoperable, notify the RSO.
2.)
! aspect the lock mechanism for ease of operation. Dirt and other foreign matter may foul the mechanism and make it inoperative. The lock may be cleaned and lubricated by using a spraying lubricant such as WD - 40 into the leck. If necessary, the lock can be removed and washed in solvent.
Caution: the camera must be empty before removing the lock.
3.)
Remove the safety plug and inspect the source outlet nipple. The outlet nipple should be round and smooth so that it will match with the 1. D. of the source tube. If the ripplo is out of round it may be straightened by using a punch or round bar on the inside of the outlet. If it cannot O
se etreigntened or is broken tne nippie must se repieced.
OPER ATING & EMERGENCY PROCEDURE orcssions ORIGINAL APPENDIX D DATE: June 29,1987 PAGE 2 of 2
4.)
Inspect labeling on exposure device. All werning signs and source identification tags should be distinct and legible. If tags are not legible, they must be replaced.
5.)
Inspect source tubes for damage such as crimps, foreign matter, ease of connecting, and disconnecting from exposure device.
(~i 6.)
Inspect source connector on drive cable. The connector V
should not be damaged or excessively worn. If the connector shows any excessive wear or damage, the drive cable must be replaced.
7.)
Inspect the remainder of the drive cable for kinks, wear, or corroded sections that may become stiff and would prevent the cable from running in the gear box. The drive cable should be cleaned and soaked in solvent or diesel fuel.
8.)
The control assembly should be dismantled and the parts should be cleaned and re-lubricated. If the drive gears or bushings show excessive wear, they should be replaceo.
l l
9.)
Inspect the drive cable housing or conduit. In any case where the inner metal liner has been damaged, the conduit must be replaced. If the outer covering has been damaged, water proof tape or a wcterproof sealer can be applied to prevent moisture from entering and causing the dri'.>e cable to corrode.
