RE: Docket #70-1193

Dear Mr. Haughney:

Enclosed, you vill find a copy of our production procedure KM4G-31-6" Glove and Bag Changing" which you were interested in seeing. Apictorial sequence of a glove change cethod very similar to our pro-cedure can be seen beginning on page 47 of the booklet, " Safe Handlingof Plutonium" which is Safety Series No. 39 of the IAEA, (1974). Ourprocedure uses an additional outer clamp.

Also please find updated sections of our Cimarron Facility EmergencyManual which reestablish procedures to follow in the unlikely eventof an accidental criticality. These procedures are Section 2, "Criti-cality Action Plan" and Section 6, " Post Accident Evacuation andAssembly Plan", both dated February 5,1979. All assigned manual holdersare being furnished a copy of these revised procedures. Please updateyour copy of our Emergency Manual with these new procedures.

If you need any additional information, please let me know.

Sincerely,

2.1 Criticality Action Plan

The plutonium plan is equipped with devices which detect ionizingradiation above normal levels such as occurs during an accidentalnuclear criticality incident. The equipment will automaticallysound air horns in the event of a criticality.

2.1.1 Ecolovee Action

In case of a criticality all employees are t'o promptlyevacuate the building. Section six (6) of this manual isto be followed.

2.2 Testine the Alarm System

No action is required for announced and posted testing of thealarm system.

2.3 Evacuation Drill

For announced and posted training evacuation drills, evacuate thebuilding when alarm is sounded. Af ter evacuation, Section six (6)[[ of this manual is to be followed.

6.1 Introduction

Complete plant evacuation is autcratic in the event of an accidentalcriticality incident. Plant evacuation is also likely to be neededin the event of fire, release of hazardous material or because ofdamage frca severe weather. The severe weather evacuation plan isincorporated in the Severe Weather Erergency section of this manual.

An orderly assembly and accounting of personnel cust be accomplishedafter a plant evacuation. Various plans in the manual describe actionsto be taken if the personnel accounting indicates the need for rescue,personnel decontamination, care of injured and other. recovery actions.

This plan describes the evacuation and assembly plan.

6.2 Evacuation and Assembiv Plan

6.2.1 Uhen the evacuation horn sounds, or when notified to evacuate,personnel are to immediatelv leave the buildinz bv the nearestexit. Personnel exitine throu2h the receotion roon will takethe s12n-in-s12n-out 1o2 with them. Health Physics personnelwill evacuate with portable survey instruments if this action

di does not delay their evacuation of the building.%

6.2.2 When out of the buildin2, go to the nearest emercenev 2 ate inthe perimeter fence (See Figure 1). The first person to reachthe gate will break the glass cover on the gate lock and unlockthe gate.

6.2.3 Once outside the cerimeter fence running is not necessarv.Proceed without delav to the energencv assemblv area locatedout-of-doors immediatelv on the west side of the EmergenevBuildine. The evacuation rcutes to be taken are shcun inFigure 1 of this plan.

6.2.4 At the assembly area, recort to vour irradiate suaervisor.

Unnecessary talk, noise or anything tending to cause con-fusion should be avoided. Take no further action unlessinstructed by supervision and remain at the emergencyassembly area until instructed otherwise. When questioned,report to the supervisory personnel any inf ormation relatingto the emergency situation which you may consider importantfor evaluation or control of the incident.

6.2.5 Health Physics personnel will make a quick survey for radia-tion levels and otherwise assess the assembly area suitablity;reporting their findings to the Emergency Director.

In the event that the emergency building assembly and controlarea are found unsuitable an alternate assembly area will bedecided upon by the Director. If possible, the alternate areawill be on Kerr-McGee property. The emergency building area isjudged unsuitable:

A. If it is destroyed, badly damaged or on fire.

B. If heavy smoke, fumes or radioactive fallout are enveloping--

,; the area.

C. For non-injured personnel when external radiation levels

(field dose rates) enmited for the accident source (plant)exceed 50 mr/hr.

D. For all personnel when external radiation levels (fielddose rates) exceed 5 REM /hr. (Max. reading on " Cutie-Pie"instrument).

6.2.6 Supervisors will make a " head count" of the personnel assembledand determine if all are present and/or who are absent.

6.2.7 The Emergency Director or his assistant assigns an individualto be a " recorder". The recorder collects the vistors logbooks. He checks with each supervisor and makes the personnelaccounting. He informs the Director of his accounting: wi:Spartic'ilar attention to any persor :ho is missing.

6.2.8 b'henever possible , the Emergency Director vill make thecontrol room (office area) of the Erergency Building hisheadquarters for subsequent action plans.

6.3 Ouick Sort

Injured personnel and those who feel they have been exposed tohigh level radiation or affected by chemicals from a release ofhazardous material are to make this known to their supervisorimmediately af ter the head count. The supervisor will have thesepeople stand in front of his group of personnel. Persons whosubsequently feel ill (nausea, faint, shock, incoherent, etc.)will also be placed in front of the group. The supervisor willobtain first aid assistance fro = Health Physics personnel forthose persons needing i= mediate attention. The supervisor willinform the Director of these individuals and the " recorder" willdocument the names and apparent condition of the affected personnel.

In the event a criticality incident has occurred Health Physicspersonnel will survey affected persons for induced activity byplacing the open probe of a GM type monitoring instrument towards,_

%, the body under the left arm pit. (Deduct background readings'- and check for contamination). Readings of 1 Mr/hr (a-3,200 c/z)

indicates a neutron exposure of approximately 50 rad. (Note -The civil defense type C.M. ins trument at the Emergency Buildingis calibrated for this evaluation).

6.4 Further Action

6.4.1 If personnel are injured and/or contaminated see Section48 of this manual " Care of Injured and/or ContaminatedPersonnel".

6.4.2 Evaluate remaining hazards using Section 7 of this manual" Post Accident Hazard Evaluation and Re-Entry for Rescue".
