3 ISSUE DATE:JAN 0 51984 INTRODUCTION PAGE OF 3 4 1.3 Basis The General Health Physics Plan is based on the regulations and requirements established by the USNRC. These regulations and requirements were established from recommendations of the Inter-national Commission On Radiological Protection (ICRP) and the National Council On Radiation Protection and Measurements (NCRP),
leading authorities on radiation protection.
Additionally, Company policy statements in Section 12 of this plan provide the basis for specific requirements detailed in this Plan.
1.4 Responsibilities The ultimate responsibility for radiation safety rests with each -
individual. Each person is responsible for maintaining their exposure ALARA during the performance of their duties. Indivi-duals are responsible for complying with all Radiation Controlled Area rules, procedures and safety practices and reporting to their immediate Supervisor, conditions or practices which are unsafe.
The Manager of Plant Operations has the overall responsibility for tho establishment and implementation of the General Health Physics Plan for personnel radiation protection.
ble for compliance with the applicable Federal and StateHe is responsi-regulations pertaining to radiological safety.
, Station Supervision is responsible for assuring that personnel comply with all requirements of the Plan.
sible for maintaining Supervision is respon-and collective (group) personnel exposure ALARA on an individual basis. Additionally, Supervision is responsible for maintaining a current knowledge of personnel exposure and controlling such exposure so that limits are not exceeded and the ALARA concept is properly implemented.
The Radiation Protection Section is responsible in particular for development and implementation of the General Health Physics Plan.
The responsibility for implementation includes compliance with all Federal and State regulations, establishment and evalua-i tion of the plant radiological working environment, ALARA implementation, and personnel exposure control, monitoring and evaluation.

COMANCHE PEAK STEAM ELECTRIC STATION SECTION: 2.0 GENERAL HEALTH PHYSICS PLAN REVISION: 4 ISSUE DATE: MAY 011986 RADIATION PROTECTION STANDARDS PAGE 2 OF 4 2.0 Radiation Protection Standards i
2.1 Development of Standards Radiation Protection standards were developed to assure that the risk associated with radiation exposure is acceptable to the individual and the population at large in view of the benefits received from the use of radiation and radioactive materials.
." Dose standards have been established such that the risk of
', radiation effects due to exposure is significantly less than the '.
risk associated with job hazards present in any occupation not involving radiation exposure.
Controversy exists over the effects of very low doses of radia-tion received over a long period of time. This issue will probably remain controversial for a long time since the effects
! are of the type which can only be observed statistically. The Radiation Protection Section will provide information, counseling and guidance to any employee concerning the effects of radiation and the CPSES program for radiation safety and protection.
2.2 Personnel Exposure Limits
! The USNRC has developed personnel radiation exposure limits following the criteria indicated above and these limits are set as CPSES.
the maximum permissible occupational exposure limits for It should be recognized that the philosophy of ALARA is dedicated to reducing exposure to radiation to the minimum practicable, therefore, these limits are not goals for exposure usage rather they are the framework in which ALARA shall be applied, a) Radiation Workers The following maximum permissible exposure limits apply to all radiation workers except those who are pregnant.
Personnel under eighteen (18) years of age will be pro-hibited from Radiation Controlled Areas.

Personnel who are assigned dosimetry devices shall wear them at all times within Radiation Controlled Areas and are responsible for their safekeeping. All dosimetry devices shall be serviced, maintained and evaluated by Radiation Protection. Personnel assigned dosimetry devices shall not tamper with them in any way or cause them to be exposed or the dose otherwise altered except during the performance of work requirements at CPSES. Personnel dosimetry devices shall not be removed from CPSES premises without prior authorization and approval by the Radiation Protection Engineer. Lost or damaged dosimetry devices shall be reported to Radiation Protection immediately.
Dosimetry devices shall normally be worn on the front of the body, between the waist and head and if more than one device is issued they shall be worn together. Other placement of dosimetry will require prior approval by Radiation Protection. Dosimetry shall be worn so as to prevent contamination of the dosimetry itself.
3.1 External Dosimetry The official and permanent record of an individual's external radiation exposure wil1 be obtained frem thermoluminescent dosimeters (TLD's). Badges will be issued to individuals requir-ing dosimetry and will contain several TLD elements to be used for assessment of external exposure. Dosimeters (TLDs) will be processed periodically on a scheduled basis to determine each individual's exposure, and new badges issued. Processing frequency may be increased depending on each individual's work requirements within the Radiation Controlled Area.
Additionally, a pocket ionization chamber dosimeter will be used for estimating personnel exposure for specific jobs and between periods of badge (TLD) processing. The pocket dosimeter will allow dose control by the individual since it can be read direct-i ly at any time. Pocket dosimeters shall be reset (Zeroed) by Radiation Protection prior to exceeding the maximum dose indi-cated on the scale. Each individual shall return his pocket dosimeter to Radiation Protection for resetting (Zeroing) when the indicated dose is 75% of full scale on the dosimeter.

2 ISSUE DATE: JAN 0 51984 RADIOLOGICAL CONTROL INCIDENTS PA OF 2 4 8.0 Radiological Control Incidents Radiological control incidents are events which involve the actual or -
potential loss of control of radioactive materials, concentrations or radiation dose rates. Loss of control creates the potential for 4 -
personnel injury, damage to equipment or facilities, and financial loss due to cleanup or disposal. Prompt action is necessary to minimize conditions.the impact of or prevent the loss of control of radiological Each person is responsible for being alert to any situa-tion which could lead to a loss of control and reporting such situations promptly to the Shif t Supervisor and Radiation Protection.
Immediate action will be taken to insure the safety of all personnel, evaluate the radiological conditions, minimize the consequences, and
- reestablish control as quickly as possible.
The Radiation Protection Engineer or designee shall determine if incidents require notification to theas tions State, USNRC, or other agencies and shall ef fect such notifica-required.
and responses is provided below.Information concerning some of the major incide 8.1 Personnel Exposure in Excess of Limits If an individual exceeds a personnel exposure limit, administra-tive or mandatory (10CFR20), or it is suspected that a limit has been exceeded, it shall be reported to the Radiatiqn Protection Engineer immediately. Such an individual will be prohibited from entering a Radiation Controlled Area until the actual dose received is ascertained and approval and authorization from the Radiation Protection Engineer is granted. If it is suspected that the dose received could result in illness or injury, prompt medical care shall be provided for the individual. Surveys and sampling by Radiation Protection will be initiated upon notifica-tion of a potential overexposure to assure prompt identification of radiological conditions which the individual was exposed to.
Once the initial response to protect the individual and establish the dose and radiological conditions present during the incident has been taken, an official investigation will be initiated.
reports of overexposure investigations shall be sent to the Alll Manager of Plant Operations and a copy of the report maintained in the individual's personnel exposure history file.
8.2 Loss of Control of Radioactive Material Loss of control includes spills, unexpected high airborne acti-vity, unplanned release of radioactive materials, unexpected high

As in all radiological incidents, the initial action shall be to protect personnel then minimize the spill or consequences of the loss of control and reestablish control as quickly as possible.
The consequences of the loss of control shall then be determined and formal investigation and reporting made as required.
8.3 Fire in a Radiation Controlled Area Fires involving radioactive materials require the assumption that airborne activity exists and therefore, respiratory protection is mandatory. Only personnel trained in radiation protection shall be involved assistance is in fighting such fires, unless off-site fire fighting required.
When off-site fire fighting personnel are involved, they shall be accompanied by TUGC0 personnel trained in radiation protection. The response will be to assure the safety of personnel first, then to minimize the spread of fire and damage, and of course extinguishing the blaze as soon as possible.
All equipment (including that to fight the fire) and areas affected by the fire, smoke and ventilation from the fire area vill be assumed contaminated until proven otherwise.
Radiation Protection shall provide approval and authorization for re-entry, recovery and decontamination work, after the fire is extinguished. Working times shall be established by Radiation Protection during the fire fighting procedure and for subsequent cleanup to assure personnel exposures do not exceed limits.
Radiation protection methods and responses for loss of control of radioactive material will apply to all fires involving such material.
