,s 5.1 All Emergency Personnel --
5.1.1 The requirements of the Health Physics Procedure Manual and the Radiation Protection Manual shall be applicable during all radiological emergencies, except as authorized by the RPD or ED. 5.1.2. Priorsto entering a Radiation Hazard Area or highly contaminated area during an Emergency, an Emergency Radiation Work Pemit (ERWP, Fonn AD-11.1) must be completed. 5.1.3 For emergency actions requiring immediate access to radiation hazard areas, the ERWP may be bypassed. Approval of the RPD or ED is required and the ERWP must be completed as soon after the entry as possible.- , t 5.1.4 For any entry where an exposure greater than 10 CFR 20 limits is 9, likely, an Authorization For Increased Exposure (Form AD-11.3) must be cmpleted. NOTE: For the purposes of emergency repair / operation, personnel will not be allowed to receive a dose exceeding 25 REM to the whole body. 5.2 Emergency Entry Team , 5.2.1 An Emergency Entry Team shall be formed for entries into highly radioactive or contaminated areas for the purpose of search and rescue on 11fe saving missions. 5.2.2 The RPD shall designate an Entry Team Coordinator. 5.2.3 Communications will be maintained via two-way radios between the Entry-Team Coordinator and the In-Plant RET. . 5.2.4 Only self-contained pressure demand respiratory equipment shall be l used for worker protection during emergency entries. . 5.2.5 Each t am shall be briefed prior to entry. The briefings shall cover: purpose of the mission; exposure limits; work methods for reduced exposures; conditions expected to be encountered; abort l O instructions; stay times; personal dosimeter rionitoring; respiratory protection equipment and anti-C clothing requirements.

In the absence of the RPD, the ED may authorize an overexposure directly after concurring with the on-shift HP or an In-plant RET member. 5.3.2 The RPD will infom personnel of the availability of thyroid blocking agents (Potassium Iodide) for use in accorchnce with EP-AD-18. , 5.3.3 ERWP's must be reviewed and approved by the RPD. . 5.4 In-plant Radiation Emergency Team l 5.4.1 All irplant radiological conditions will be reported to the Radiological Protection Director. I 5.4.2 The RET will make radiological assessments of all inplant areas requiring access and occupation during an emergency. 5.4.3 The projected amount of time inplant emergency worters will be allowed to stay in a radiation and/or contaminated area shall be detemined in accordance with Stay Time (Fom AD-ll.2) and shall include a review of:
- a. Projected route exposures .
- b. Measured dose rates and airborne concentrations l
- c. Personnel exposure history
- d. Projected duration of task
- e. Infomation on current plant conditions and the plant area under consideration ( i. .
5.4.4 Continous radiation monitoring coverage will be provided in occup'ied areas when the potential for increased radiation levels exist - and the area is occupied. 5.4.5 Radiation surveys need not be performed in areas of extremely high radiation levels. Rather, surveys should be perfomed only if entry into these areas is required for other emergency actions. (O) V 5.4.6 Air sample surveys and radiological assessment surveys shall be ccupleted depending on the nature and seriousness of the emergency.

' l DATE: M 21 E I PAGE 4 of 8 5.4.7 For all entries into a Radiation Hazard area, exposures to airborne concentrations of radioactivity shall be limited by the following:
- a. Whenever practicable, total exposure of any individual during---
an emergency should be limited to 40 MPC-hours. MPC hours are calculated by multiplying the concentration in terms of - the number of MPC's by the total time of exposure (in hours). -
-b. : If emergency operations demand, total exposure of any individual shall be limited to 1,200 MPC-hours. This is roughly equivalent to the 3 Rem / quarter limit for external radiation exposure.
c.; Limits for exposure to Xe-133 and other noble gases are based on beta plus gamma dose limits to the skin and whole body.
- d. An integrated exposure of 10,000 MPC-hours for nuclides with short effective half-lives is roughly equivalent to an external, whole-body exposure of 25 Rem and should be recdived only with I
the approval of the Radiological Protection Director or Emergency o i Di recto r. Similar exposure to nuclides with long effective (E j i half-lives are to be avoided and should be restricted to 1,200 MPC-hours as in b above.
- e. Since t'e effects of external and internal exposure are additive, personnel should avoid exposures over 1,200 MPC-hours, even in the event of life-saving or rescue action, unless external radiation fields are minimal and unless ef fective half-lives are short.
- f. Personnel who have been exposed to more than 10,000 MPC-hours
--shall be removed from further emergency duty, @ ole body
' counted, and referred to a physician for attention. 5.4.8 For all special entries the RET shall review with the team members the task to be performed including the following where applicable.
- a. Potential stress conditions and problems -
- b. Work methods
- c. Number of personnel required
- d. Allowable exposure limits ,
- e. Tools, equipment, and parts
- f. Lighting
- g. Communications requirements
