Revision 1 12/16/77 THREE MILE ISLAND NUCLEAR STATION STATION HEALTH PHYSICS PROCEDURE 1681 CONTROL OF CONTAMINATED SPILLS 1.0 PURPOSE This procedure describes general guide lines to be utilized in the event of a radioactive contaminated spill and sets forth minimum requirements for the training of personnel in the proper response to contaminated spills.
2.0 DISCUSSION The detailed action which should be initiated in the event of a radioactive contaminated spill will vary with each incident; however.
there are several general rules or guides which are applicable for most spills.
These guidelines are set forth in order that all personnel will be aware of the proper response to all spills regardless of the physical state of the contamination, (i.e., solid, liquid or slurry).

Revision i 12/16/77 5.2 Emergency Rid 1olog:c;? Ccatrol Caoinets should be equipped per Form 1631-1.
The cabinets are to be located in an appropriate area near the elevator on each level of the Auxiliary Building.
A copy of Form 1681-1 is to be kept in each cabinet.
5.2.1 Emergency Radiological Control Cabinets should be inventoried and re-stocked as needed and at least quarterly.
They should also be inventoried and re-stocked af ter each use.
A seal may be utilized so as to indicate if the cabinet has been used.
Form 1681-2 is to be used to record the performance of each inventory and will be kept in each cabinet.
5.3 General Guide Lines - The following general guide lines are provided to assist in the development of detailed instructions for specific locations and make available a set of simplified rules.
The sequence of action is not mandatory since several may occur simultaneously.
5.3.1 Stop the Spill - If the spill is from a system which may release more material, promptly stop the leakage, if possible.
In the event the spill presents a serious hazard to your health, no ac tion should be taken.
5.3.2 Warning Personnel - Contact the Control Room and other personnel in the immediate area and inform them of the spill.
The Radiation Protection personnel will be notified of the spill as soon as possible.
Decontamination will be guided by the Radiation Protection personnel.
If any personnel have become contaminated, they should be instructed to remain in the general area so as not to spread the contamination to other areas of the facility.

Revision 1 12/16/77 5.3.3 Contain the Spill - If possible, the contaminated material which has been released should be contained to as small an area as possible.
This may involve use of blotting paper or rags to prevent a liquid spill from spreading or may require that all exits and exhaust from the area be secured to prevent the spread of air-borne contamination to outside areas.
This could also involve the covering of a dry radioactive spill with damp blotting material or rags to prevent airborne contam-ination.
5.3.4 Minimize Exposure to Contamination and Radiation - Personnel should be prevented from walking through the contaminated area. All personnel should move to the outer edge of the affected area.
Personnel may be required to move outside of the room or building to reduce their exposure to high radiation levels. However, personnel must not leave the gencral arca until monitored by Radiation Protection personnel.
If personnel are required to remain in or occupy the affected area, protective clothing and respiratory equipment should be worn.
5.3.4.1 Personnel decontamination will be performed as soon as possible utilizing the guidelines in section 2.12 of the TMI Radiation Protection Manual.
5.3.5 Determine Radioactivity levels - Radiation Protection personnel will survey the affected area for radiation and contamination l evel s.
Adjacent areas will be surveyed to ensure that the contamination has not been spread unknowlingly.
Ventilation and exhaust systems will be monitored for possible contamination.
Airborne activity levels will be determined as part of the lbb 3.0 e
