DUKE POWER COMPANY McGUIRE NUCLEAR STATION

" OPERATING PROCEDURE FOR THE OPERATION OF THE POST ACCIDENT LIQUID SAMPLE SYSTEM UNIT II 1.0 Purpose The Post Accident Liquid Sampling System (PALS) provides the capacity to promptly obtain a reactor coolant sample under a nuclear reactor accident condition.

Sample acquisition during accident conditions (nonnal sampling area being 1 --

inaccessible) will help evaluate information related to:

1) The extent of core damage which has occurred or is occurring.

j 2) Types and quantities of fission products released to containment liquid and gas phases.

3) Reactor Coolant chemistry and radiochemistry. ,

2.0 Limits

, 2.1 The Post Accident Liquid Sampling System should not be used unless

,  ; one or more of the following conditions exist:

(a) The Reactor Coolant System (NC) Gross Specific Activity is expected to be or is known to be greater than 200 uCf/ml. This corresponds to a reading on EMF-48 of equal to or greater than 1.3 X 106 counts per minute.

(b) Health Physics has determined the radiation levels in the Nuclear Sampling Laboratory (NM Lab) prohibits access and use of the Nuclear Sampling System (NM) and local sample points for the Residual Heat Removal System (ND) are not accessible due to l radiation l'evels, NC activity levels (see (a) above) or can not l be used for other identified reasons. Refer to CP/2/B/8600/04, Identification and Instruction in the use of Primary Area Local Sample Points.

(c) Specifically requested by the Station Chemist or his designee.

(d) Operation required to perform monthly operational verification ,

or for maintenance and trainitig purposes.

l~ 2.5 When handling radioactive samples, good laboratory practices and techniques are essential to prevent radioactive contamination of j personnel, equipment, and physical structures. Reference applicable SRWP(s) or RWP(s) and Section 3.13 of the Chemistry Manual.

l- 3.0 Initial Conditions 3.1 In order to maintain the PALS in an operable condition at all times, the following requirements on Enclostre 9.1, PALS Monthly Checklist, l-.

l must be done monthly and be current prior to sampling.

sampling is to be performed and list on Enclosure 9.2.

p 3.3 If the containment building has been isolated due to an SI or SIS

\. , / ,

signal, no sample is to be obtained until the On-Site Support Center can decide how to un-isolate one of the sample lines.

One technicon cup of liquid sample will be analyzed via CP/0/A/8100/06, Chemistry Procedure for the Determination of Chloride in High Purity Water. Results must be adjusted via the calculation in Section 7.4, substituting ppb Cl- ,-

for ppm 8, so that dilution is taken into account. Record value in

CORRECTION OF DILUTION VOLUME To correct the dilution volume, divide the final radiation reading (Section 5.10.5) by 3 rem /hr, then multiply this by 250 ml to obtain desired dilution volume in Section 5.6.3.

m Example: Reading in Section 5.10.5 = 10 rem /hr then 10 rem /hr x 250 = 833 ml 3

Go back to Section 5.2 and repeat the sample sequence, using a dilution volume of 833 m1 in Section 5.6.3 instead of 250 mis.

NOTE: Set Totalizer 20 mis over dilution volume wanted as there is a 20 m1 loss do to a dead loop of tubing. I w
