1.1 Purpose and Scope
1.1.1 Purpose
The purpose of this procedure is to establish the steps necessary to complete the sampling and analysis of the Reactor Coolant System and of containment atmosphere under accident conditions in a safe, effective manner.
1.1.2 Scope
1.1.2.1 This procedure will define the responsibilities of chemical analysis personnel who will be involved in post accident sampling and analysis activities.
1.1.2.2 This procedure will also outline the steps necessary to complete the following:
a.
Initiation of the Post Accident Sampling System (PASS) b.
Post Accident Sampling and Analysis c.
Shutdown of the PASS 1.2 Definitions 1.2.1 Post Accident Sampling System (PASS): A system composed of various components that provides the capability to obtain Reactor Coolant System 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.
1.3 Principle 1.3.1 In the'bvent that OEPP01-ZA-0002 (Emergency Direction) activates any portion of the Emergency Plan relating to the integrity of the Reactor Coolant System (RCS), fuel cladding failure, or a potential LOCA, it will be necessary to monitor both plant chemical and radiochemical conditions. Parameters of the Reactor Coolant System (RCS), Residual Heat Removal (RHR) System, and Reactor Containment Building (RCB) sump that will be monitored include pH, specific conductivity, dissolved oxygen, gross gamma activity, boron, chloride, and dissolved hydrogen. Also, the RCB atmosphere will be monitored for gross gamma activity, hydrogen, and oxygen.
From these analytical results, it will be possible to assist in assessment of the accidents" severity, the condition of the core, and verification of the shutdown margin.

1 Post Accident Core Damage Assessment IPCP08-AP-0001 Sampling and Analysis Rev. O Page 3 of 11 1.3.2 This procedure establishes a chronological set of events that 4
will occur in the event of an accident up to a design-base type. These will include the set-up of associated instrumentation, inline and offline monitoring of the various parameters, liquid and gaseous sampling, performing required lab analyses, and shutdown of the PASS when completed. This procedure will also describe the responsibilities of the Chemical Analysis Supervisor, the Lead Chemical Technician, and the Chemical Technician.
1.4 Limitations None 2.0 Prerequisites 2.1 Ensure that a radiation survey has been performed and a Radiation Work Permit (RWP) has been issued in accordance with OPGP03-ZR-0002 (Radiation Work Permit.) An Emergency Radiation Work Permit'may have to be issued immediately af ter the entry.
1 2.2 Entry to and exit from the Pass facility will be coordinated through and directed by the Emergency Director.
3.0 Precautions 3.1 Due to the possibility of high contamination levels, personnel I
entering the PASS facility will dress out in accordance with the RWP, or as directed by Health and Safety Services.
i 3.2 In addition to accepted practices for laboratory safety, additional safety requirements listed in Section 3.7 of OPCP01-ZA-0017 (Post Accident Sampling and Analysis Program) will be followed.
l 4.0 Procedure 4.1 Responsibilities i'
4.1.1 The Chemical Analysis Supervisor is responsible for l
supervising all post accident sampling and analysis activities.
4.1.2 The Lead Chemical Technician (LCT) is responsible for l
initiating operation of the PASS upon direction from the j
Emergency Director. The LCT is responsible for supervising all shift post accident sampling and analysis activities, and for reviewing and reporting all analytical results to the Emergency Director.
Post Accident Core Damage Assessment IPCP08-AP-0001 Sampling and Analysis Rev. O Page 4 of 11 4.1.3 The Chemical Technician is responsible for taking all required post accident samples and performing all associated analyses, then reporting results to the Lead Chemical Technician.
4.2 Initiation of PASS NOTE The following steps should be performed in the order in which they are written. However, some steps may be omitted as directed by the Lead Chemical Technician based on the fact that portions of the system may already be in operation or that certain backup analyses may not be required.
4.2.1 Upon rotification from the Emergency Director that any portion of the Emergency Plan has been activated relating to the integrity of the RCS, fuel cladding failure, or a potential LOCA, perform the following steps.
4.2.1.1 Verify that the PASS has been placed in operation in accordance with IPCP08-AP-0002 (Operation and Maintenance of the Post Accident Sampling System).
4.2.1.2 Verify that the PASS in-line analyzers have been standardized in accordance with IPCP08-AP-0002 (Operation and Maintenance of the Post Accident Sampling System).
4.2.1.3 Verify that the Gamma Spectroscopy System has been standardized in accordance with OPCP09-ZO-0001 (Operation of the Gamma Spectroscopy System).
4.2.1.4 Verify that standardizations for the following backup PASS analyses have been completed in accordance with the indicated procedures, if backup analyses will be required.
a.
Boron-1PCP08-AP-0006 (Backup Determination of Boron-Post Accident).
b.
Chlorides-1PCP08-AP-0007 (Backup Determination of Chlorides-Post Accident).
