3.2 It has been determined by the Shift Supervisor, Plant Radiation Protection Supervisor, their designees, or other responsible plant staff personnel, that additional information on the poten-tial releases through the plant vent is needed.4.0 PRECAUTIONS'.
4.1 Very high dose rates and high levels of airborne radioactivity may be pr eseht in unexpected locations in the Auxiliary Building.Precautions to keep internal and external exposure to a minimum shall be taken.These may include, but are not.limited to the following precautions:
4.1.1 4.1.2 4.1.3 At least two individuals shall be sent when there is doubt about the radiological conditions in the Auxiliary Building.At least one functioning high range dose-rate instrument shall be available at all times.This normally means carrying a suitable spare instrument.
The instruments used for survey may be either GM or Ion Chamber type.If an instrument with a sealed chamber (such as the PIC-6A)is not available, an RM-16 with bullet probe may be used.Page 1 of 9 Revision 0
'I l(I+At~~Alt'tO U)E4 4 1 l~PMP 2081.EPP.027 4.1.4 Normally, if vent release conditions are serious enough to require activation of this procedure, airborne condi-tions in the Auxiliary Building would require the use of pressure demand type supplied air respirators by all personnel invol ved.5.0 ENVIRONMENTAL CONDITIONS 5.1 In all cases involving a significant increase in airborne acti-vity, licensed Control Room personnel should consult PflP 2080 EPP.001;ECC-19 and ECC-13 to determine if any emergency action levels (EAL's)have been exceeded.Upon exceeding an EAL, the proper anergency condition shall be declared and the Energency Plan activated by implementing PMP 2080 EPP.001.6.0 PROCEDURE 6.1 Obtain portable ccmmunication radio frcm the Technical Support Center, Control Room or an Emergency Station.Survey data taken at the sample station should be transmitted to the Control Room every fifteen (15)minutes.)NOTE: Communication can also be made to the Technical Support Center and Operational Support Center, if necessary or desired.6.2 Obtain calibrated, operable, dose-rate reading instruments.
This should include, i f possible, an RM-16 (2 mR/hr to 20 R/hr)with bullet probe.If the range of the RM-16 is expected to be exceeded, a PIC-6A (1 mR/hr to 1000 R/hr)survey instrument from an emergency station should be obtained for use.6.3 Carefully proceed to the 650'levation sample station.6.4 Remove the shield plug and insert the detector so that it is 6 inches from the sample line inside the shield.For exact positioning of instruments, see Figure 2 for PIC-6A, or Figure 3 for RM-16 bullet probe.6.5 If RM-16 with bullet probe is used in shield, slide lead plug up against bullet probe retainer to minimize radiation shine from sample line.6.6 Open the remote operated sample valves and start the sample pump (controls are located near the sample station).6.7 Obtain a reading on the survey instrument.
6.8 Using Attachment
<1, determine the Activity Factor at Time After Event.Page 2 of 9 Revision 0 PMP 2081.EPP.027 NOTE 1: Computer program CPM.002 may be used instead of steps 6.8 through 6.12.NOTE 2: The Activity Factors of Attachment
>1 correspond to one (1)R/hr at six inches frcm the sample line (activity uCi/cc factor units~n>h).The concentration required to give 1 R/hr will change with time.It is important that Attachment 81 be referenced frequently to insure that the proper activity factor is used.6.9 Calculate the Unit Yent Release Concentration by multiplying the measured R/hr at the sample station times the activity factor, 6.10 Calculate the Unit Yent Release Rate by multiplying the release concentration times the unit vent flowrate (in CFM)times 4.72E-EXAMPLE: 2.5 R/hr 9 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> (1 day)Activ i ty Factor=5.2E3 Release Concentration
