3.5 Moving the Selector Switch from one mode to'another stops all current system operations. Depressing the Activate button starts operation l ,

of the newly selected mode.

I 3.6 The radiation' monitor on the control panel will provide levels of

! radiation at the, sample panel. If the radiation monitor is not l working properly, then a portable survey instrument will be used

! to dete=4= radiation levels.

3.7 If problems with the pressure and/or temperature gauge are evident, such astgoing off scale or erratic response, the Selector Switch must be turned to the OFF mode and sampling discontinued until the problem is corrected. ,

3.8 If the sampling system cannot be operated, then HP/0/B/1009/15 (Ref. 2.4) will be used as an alternate method for obtaining a containment air sample. ,

3.9 Enclosure 5.5 will be used to check off the steps as the procedure is completed.

3.10 Operations must complete Enclosure 5.3 or 5.4 to bypass the Hydrogen Analyzer to bring containment air to the sampling system and to return the Hydrogen Analyzer to service after sampling is complete by Enclosure 5.6 or 517.

'3.11 The frcat' side of the sample panel is the side which contains the door.

The left and right side of the sample panel will be determined by using this fact.

3.12 If radiation levels exceed 16 R/hr and cannot be reduced by purging the system, secure operation of the panel, move to a low background area, and contact the Station Health Physicist or his designee for furtt.er instructions.

3.13 Eefore sampling operations begin, the decision must be made based on radiological conditions, in the reactor building and the sampling area whether to use a 100 ml gas bomb or a calibrated syringe for the gas sample. During emergency conditions, this decision will be made by the Station Health Physicist or his designee.

3.14 Enclosure 5.8, Valve Checklist for Sample Panel, may be used to provide assistance in determining flow inside the sample pansl. It is not intended to provide a verification for valve operation.

3.15 During accident conditions, the keys needed for sampling will be located in the Shiftman's key cabinet.

3.16 The sampling system must not be used if reactor building pressure is greater than 40 psig.

l OPERATING PROCEDURE FOR POST-ACCIDENT CONTAINMENT i

l AIR SAMPLING SYSTEM 1.0 Purpose  !

This procedure describes the operation of the Post-Accident Containment Air Sampling System which is used to obtain a prompt containment air

sample under accident conditions while keeping radiation exposure ALARA.

This procedure is also used to perform the semi-annual functional test of de system 2.0 References 2.1 Duke Power Company Nuclear Station Post-Accident Containment Air Sampling System Manual 2.2 HP/0/3/1006/07, Procedure for Preparation of Gas Calibration Sources 2.3 CP/1/A/2002/04C, Operating Procedure for the Post Accident Liquid Sampling (PALS) System 2.4 HP/0/B/1009/15, Procedure for Sampling and Quantifying.High. Level...

~~~

Gaseous, Radioiodine'and Particulate-Radioactivity 2.5 EP/0/A/1800/04, Loss of Coolant 3.0 Limits and Precautions 3'.1 The sampling cycle will require two (2) qualified technicians approximately one (1) hour per sample, of which about ten .(10) _ .

minutes will be spent in the sample panel area. One qualifie'd technician will operate the control panel while the other will _

perform transit duties to and frem the panel.

3.2 Personnel communications can be achieved by phone.

Unit 1 & 2 - Ext. 1268 (by column AX-38)

Unit 3 -

Ext. 1396 (by door to RCA) 3.3 The following items will never be used on the panel.

a. Trap Area Evacuation

b. Fast Sample Dilution

HP/2/A/1009/17 Pdga 2 of 8 3.4 The Recire Pump must never be used at any pressure other than 0-inches

of Mercury. ~

l 3.5 Moving the Selector Switch from one mode to'another stops all current system operations. Depressing the Activate button starts operation of the newly selected mode.

3.6 The radiation monitor on the control panel will provide levels of radiation at the sample panel. If the radiation mor.itor is not working properly, then a portable survey instrument .will be used to determine radiation levels.

3.7 If problems with the pressure and/or temperature gauge are evident, such as going off scale or erratic response, the Selector Switch must be turned to the OFF mode and sampling discontinued until the problem is corrected.

3.8 If the sampling system cannot be operated, then HP/0/B/1009/15 (Ref.

2.4) will be used as an alternate raethod for obtaining a containment air sample.

3.9 Enclosure 5.5 will be used to check off the steps as the procedure is completed.

3.10 Operations must complete Enclosure 5.3 or 5.4 to bypass the Hydrogen Analyzer,to bring containment air to the sampling system and to return the Hydro' gen Analyzer to service after sampling is complete by Enclosure.  ;

. 5.6 or 5.7.

" ' ~ '

3.11 The front' s[d'e of 'the sample panel is the side which contains the door.

The left and r'ight side of the sample panel will be determined by

. using this fact.

3.12 If radiation levels exceed 16 R/hr and cannot be reduced by, purging the system, secure operation of the panel, move to a low background area, and contact the Station Health Physicist or his designee for further instructions.

3.13 Be. fore sampling operations begin, the decision must be made based on radiological conditions in the reactor building and the sampling area whether to use a 100 ml gas bomb or a calibrated syringe for the gas sample. During emergency conditions, this decision will be made_by the Station Health Physicist or his designee.

~

3.14 Enclosure 5.8, Valve Checklist for Sample' Panel, may be used to provide assistance in determining flow inside the sample panel. It is not=

intended to provide a verification for valve'operat. ion.

3.15 During accident conditions, the keys n'eeded for'sa,pling will be located in the Shiftman's key cabinet.

l 3.16 The sampling system must not be .used if reactor building pressure,is greater than 40 psig.

' This procedure describes the operation of the Post-Accident Containment Air Sampling System which is used to obtain a prompt containment air sample under accident conditions while keeping radiation exposure ALARA.

This crocedure is also used to perform the semi-annual functional test of the system.

2.0 References 2.1 Duke Power Company Nuclear Station Post-Accident Containment Air Sampling System Manual 2.2 HP/0/B/1006/07, Procedure for Preparation of Gas Calibration Sources 2.3 CP/1/A/2002/04C, Operating Procedure for the Post Accident Liquid Samplingt(PALS) System

system operations. Depressing the Activate button starts operation l of the newly selected mode. ,

3.6 The radiation monitor on the control panel will provide levels of radiation at the sample panel. If the radiation monitor is not working properly, then a portable survey instrument will be used to determine radiation levels.

3.7 If problems with the pressure and/or temperature gauge are evident, such as going off scale oc erratic response, the Selector Switch must be turned to the O_q mode and sampling discontinued until the Problem is corrected.

3.8 If the sampling system cannot be operated, then HP/0/B/1009/15 (Ref. 2.4) will be used as an alternate method for obtaining a containment air sample.

3.9 Enclosure 5.5 will be used to check off the steps as the procedure is completed.

3.10 Operations must complete Enclosure 5.3.or.5.4 to bypass the Hydrogen Analyzer to bring containment air to the sampling system and to return the Hydrogen Analyzer to service after sampling is complete by Enclosure 5.6 or 5.7.

._ _ 3.11 The front side of the sample panel is the side which contains the.d_oor. _

The left and right side of tL sample panel will be determined by~

using this fact.

3.12 If radiation levels exceed 16 R/hr and cannot be reduced by purging the system, secure operation of the panel, move to a low background area, and contact the Station Health Physicist or his designee for further instructions.

~

~

3.13 Before sampling operations begin, the decisica must be malis ba' sed on'~

radiological conditions in the reactor building and the sampling area _

whether to use a 100 ml gas bomb or a calibrated syringe for the gas sample. During emergency conditions, this decision will be made by the Station Health Physicist or his designee.

. 3.14 Enclosure 5.8, Valve Checklist for Sample Panel, may be used to provide assistance in determining flow inside the sample panel. It is not intended to provide a verification for valve operation.

3.15 During accident conditions, the keys needed for sampling will be located in the Shiftman's key cabinet.

3.16 The sampling system must not be used if reactor building pressure is greater than 40 psig.
