Revision 2 04/28/77 THREE MILE ISLAND NUCLEAR STATION STATION HEALTH PHYSICS PROCEDURE - 1682 Control of Contaminated Tools, Equicment and Material 1.0 PURPOSE This procedure outlines the proper treatment of contaminated equipment to prevent the spread of radioactivity to clean areas and to minimize exposures to personnel in radiation work areas.
2.0 DISCUSSION Tools and equipment used to service contaminated machinery will likely become contaminated.
Such items will.be stored in an appropriate area such as the " HOT" Instrument Repair Shop", the Decontamination Room or Reactor Building.
In some instances it will be desirable to use this cont?yinated equipment in other areas of the plant.
Authority to do so will be granted by the Radiation Protection Supervisor / Foreman or designated alternate.

5.1.1 Tools, equipment and material used in contaminated and radiation areas will be given unconditional release to cle'an areas if all exposed and unexposed parts and surfaces are free of 2
contamination (less than 1000 DPM/100 cm beta-gamma anc es 139 1.0 o

than 100 DPM/100 cm alpha, and the radiation level at 1 inch is less than 0.4 MR/Hr.
5.1.2 Upon completing a Radiation Work Permit area job, equipment and tools used are to be placed in a clean yellow poly bag and brought to the decontamination room.
5.1.3 Leave the equipment and tools in the decontamination room and notify the Radiation Protection Department.
5.1.4 The Radiation Protection Department representative will, if he can at the time, conduct a survey of the equipment to determine contamination levels.
5.1.5 If the Radiation i atection Department representative is not available to perform a contamination survey of the equipment at the time of request, the bag of tools or equipment must be marked with a " Caution - Radioactive Materials" tag and it is i
the requestors responsibility to put the equipme:it in his own department hold up area.
The bag of equipment may at some other mutually agreeable time be brought back to the decon-tamination room for a survey and/or decontamination.
NOTE:
If a piece of equipment, tool or other item is neede/ immediately, all efforts will be made by the Radiation Protection Department to perform a survey at the time of request.
5.1.6 Any item that cannot be decontaminated after a reasonable effort is to be retained by the department who is responsible 3
for that item in their own hold up area within the confines of the controlled area.
The items will be piaced in poly or any suitable container to control the spread of contamination and 2.0 e

Revision 2 04/23/77 clearly marked with a " Caution - Radioactive Materials" tag.
If this poses any problems refer to the Radiation Protection Supervisor / Foreman for guidance.
5.1.7 If an item is ready for release to a clean area of the plant a green radiation and contamination clearance tag will be placed on the item.
The person or department responsible for the item will be notified to pick un the item.
5.2 Conditional Release to Clean Areas 5.2.1 Items may be released to clean areas for conditional use if the intensity of radiation does not exceed 1.0 mR/hr. at one inch from any accessible surface, removable contamination does 2
not exceed 1000 DPM/100 cm Beta-Gamma activity or 100 DPM/100 cm activity, and the use of the items is approved by the Radiation Protection Supervisor / Foreman.
These items will be tagged with a properly completed " Caution - Radioactive Materials" tag.
No tool, equipment or material normally stored in a contaminated equipment storage areas such as the Decontamination Room or the Hot Instrument Repair Shop will be disassembled in any other area, unless authorization is granted by the Radiation Protection Supervisor / Foreman.
5.3 Release to Controlled Areas Equipment, tools and material used in a RWP area may be released to a Controlled Area for conditional use if intensity of radiation is less than 5.0 mR/hr at one inch from any accessible surface and if smearable contamination on all surfaces does not exceed 100 DPM/100 2

2 cm alpha, and 1000 DPM/100 cm beta-gamma.
These items will be tagged with a properly completed " Caution - Radioactive Material" 3.0 bb l'

.g, 1632 Revision c 04/28/77 tag. Such items will not be used, worked on or disassembled without prior survey and recommencation for control by Radiation Protection Supervisor / Foreman.
5.4 Radioactive Equipment All items from which the intensity of radiation is greater than 5.0 mR/hr. at one inch from any accessible surface shall be properly marked or tagged and placed in a contaminated equipment storage area or an appropriately posted Radiation Work Permit area.
These items may not be handled without orior survey and recommendation for Control by the Radiation Protection Superviosr/ Foreman.
5.5 Regulated Equipment Equipment of a portable nature, such as hand tools, small pumps and motors of such design which makes decontamination impractical, will be considered regulated equipment.
Regulated equipment may have 2
contamination up to 100,000 DPM/100 cm beta-gamma and 10,000 2
DFM/100 cm alpha, as determined by a smear test, and may have radiation levels up to 10 mR/hr at one inch.
It can be used only in the Control Areas by workers having a properly completed Radiation Work Permit, wearing protective clothing and proper monitoring devices.
These items will be marked with a properly filled c Jt
" Caution - Radioactive Materials" tag.
The Radiation Protection Supervisor or his designated alternate may permit the use of equipment having radiation levels higher than 10 mR/hr., af ter consideration of all the factocs involved, i.e., the nature of the equipment, the frequency of use, and the length of time it may be in use.
