Post Accident Sampling OPCP01-ZA-0017 and Analysis Program Rev. O Page 3 of 18 1.0 EHEPose and Scope 1.1 This procedure describes the facilities and the program for sampling and analyses to monitor plant chemical and radiochemical parameters following a design basis accident, and the support programs necessary to assure sampling and analysis activities are performed in a safe and qualified manner.
1.2 This procedure is an extension of the sampling and analysis program for the chemical laboratories described in OPCTOl-ZA-0010 (Chemical Laboratory Sampling and Analysis Program).
2.0 Definitions 2.1 POST ACCIDENT SAMPLING SYSTEM (PASS): A system composed of various components that provides the capability to obtain reactor coolant and containment atmosphere samples and perform required analyses
. during post accident conditions within 3 hours3.472222e-5 days <br />8.333333e-4 hours <br />4.960317e-6 weeks <br />1.1415e-6 months <br /> or less from the time a decision is made to sample.
2.2 LIQUID AND GAS SAMPLE PANEL (LGSP): The major fluid / mechanical component of the PASS whose-purpose is to provide necessary in-line instrumentation, gas stripping equipment, grab sample (diluted and undiluted) collection points, and dilution loops.
2.3 SAMPLE COOLER RACK (SCR): A component of the PASS whose purpose is to provide temperature conditioning of liquid samples prior to entering the LGSP.
2.4 INSTRUMENT PANEL (IP): A component of the PASS whose purpose is to provide necessary the remote monitors and recorders for the in-line instrumentation located in the LGSP.

3.3.1 Laboratory Facilities and Instrumentation The following permanent plant laboratories are provided to 1
support the Post Accident Sampling and Analysis Program.
4
- 1) Post Accident Chemistry Laboratory (one per unit) 4 4
- 2) Counting Room (one per unit)
'A brief description'of each laboratory, including its location, special design features, major analytical instrumentation, sample lines, power supply, and layout is provided in Addendum 1.
3.3.2 PASS Operation Overview Samples are cooled by the SCR prior to entering the LGSP.
Operation of-the LGSP-during the sample line flushes, 4
sampling and in-line analysis is conducted from the ECP.
The only time a technician is required to be at the LGSP is to i
connect containers for grab sampling, any manual valving operations and collection of samples (diluted and undiluted).
Once the panel has been flushed and placed into operation, all readings from the in-line analyzers are taken remotely at the IP.
The only required handling of liquid grab samples j
(diluted) is for preparation for gamma isotopic analysis, or backup analysis.
3.3.3 Sample Points Collection of liquid samples is covered in 1PCP08-AP-0003/2PCP08-AP-0003 (Sampling and Analysis of RCS, RHR, and RCB Sump - Post Accident), collection of gaseous samples is covered in 1PCP08-AP-0004/2PCPO8-AP-0004 (Sampling and Analysis of RCB Atmosphere - Post Accident).
Specific sample points for the PASS are as follows:
Liquid Sample Points
- RCS Hot Leg No. 1
- RCS Hot Leg No. 3
- RifR Loop A
- RHR Loop B
- RHR Loop C
- Containment Normal Sump Gaseous Sample Points l

O Page 6-of 18 3.3.4 Implementation of the Pass Program In the event that OEPP01-ZA-0002 (Emergency Direction) activates any portion of the Emergency Plan relating to the integrity of the RCA, fuel cladding failure or a potential LOCA, the Chemical Analysis Supervisor shall impliment applicable portions of the PASS Program as directed in 1PCP08-AP-0001/2PCPO8-AP-0001 (Post Accident Core Damage Assessment). 1PCP08-AP-0001/2PCPO8-AP-0001 (Post Accident Core Damage Assessment) establishes specific steps necessary to complete the following major tasks.
a.
Initiation of PASS Operation b.
Post Accident Sampling and Analysis during Accident Conditions c.
PASS Shutdown 3.3.5 Recording and, Evaluation of Data Analytical results are recorded on the appropriate Worksheet, Log Sheet, Data Sheet or other approved form as specified in the analytical procedure used.
For post accident situations, there are no acceptance criteria as such to compare the analysis results against.
All information necessary to interpret the analytical results and any other conditions or situations deemed necessary are also recorded on these forms. The results will be used to evaluate a number of plant conditions and include, but are not limited to the following:
- Core Damage
- Presence of Explosive Gas Mixtures 3.3.6 Sample Verification Accuracies for the PASS in-line instrumentation as listed in the response to the NRC regarding the requirements in NUREG 0737 Item II.B.3 (Postaccident Sampling Capabilities) are also listed in the applicable sampling and analysis procedures. Performance of cross-comparisons between the in-line analyzer chemical results and those from grab sample:;
provides verification that the in-line analyzers are working properly. Corrective action is taken if there is a discrepancy in the results and the grab sample result is verified as accurate.
Location of the in-line analyzers for the PASS are indicated in Addenda 3 and 4.
