3.0 PERSONNEL INDOCTRINATION 3.1 Description 3.1.1 PASS is an on-line system designed to sample various liquid and gaseous sample streams during accident conditions.
3.1.2 The liquid PASS system consists of an AIMS detector to perform gamma isotopic analysis of the sample streams.
3.1.3 The PASS system provides the ability to obtain liquid grab samples to be shipped off-site for analysis. [NOCS 100440,100441]
3.1.4 The PASS system has the ability to analyze boron and gamma isotopic from RCS at high pressure. This sample may be obtained from RC letdown, RCP-1A discharge, or RCP-1C suction. [NOCS 100440,100441]
3.1.5 The PASS system has the ability to analyze boron and gamma isotopic on low pressure systems. These systems include DH and RB sump. [NOCS 100440, 100441]
3.1.6 When estimating total activity for liquid grab sample shipment, the following assumptions were made:
- Core Nuclide Mix and Half-lives from RADTRAD Code Library
- 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> since reactor shutdown
- Microshield software was used to determine conversion factors for calculating total pCi from dose rate. Sample assumed to be small enough at 7 inches to represent point source. Pig is 17.75 inches tall with diameter of 7 inches.
Weight is 725 pounds. This results in effective density of 7.4 g/cc.
- Release fractions from Regulatory Guide 1.183 for gap and early in-vessel melt
- Assume no noble gas remain in unpressurized RCS/sump sample 3.1.7 When estimating core damage based on RCS sample (Enclosure 5), the following assumptions were made:
- Factor (B)is 1300 based on the following:
Assumed dilution mass = 1.3E9 grams 1300= (1.3E9 grams) x (1E-6 Ci/pCi)
- Core Inventory (D) is from RADTRAD library for 2619 MWth core
- Expected fraction in gap (F)is from NUREG 1465
- Expected in-vessel melt release fraction 100% melt (G) is from NUREG-1465 I CH-632 I Rev. 2 1 Page 6 of 77
3.2 Definitions 3.2.1 AIMS Automated Isotopic Measurement System 3.2.2 EC Emergency Coordinator 3.2.3 PASS Post Accident Sampling System 3.2.4 RE-ENTRY Return of personnel to an area evacuated by an emergency condition 3.2.5 RMT Radiation Monitoring Team 3.2.6 TMI Three Mile Island nuclear power plant 3.2.7 IRP Instrument Relay Panel 3.3 Responsibilities 3.3.1 EC or designee shall authorize re-entry.
3.3.2 OSC Chemistry Coordinator
- Ensures EC approval for re-entry has been obtained
- Determines which sections of procedure are to be performed during re-entry
- Ensures re-entry prerequisites are complete klof 3.3.3 This procedure is performed by a qualified Emergency Sample Team member.
3.4 Limits and Precautions 3.4.1 Any or all of this procedure is done by direction of the EC or designee.
3.4.2 Re-entry must have RMT preplanning, concurrence, and coverage as outlined in EM-104, Operation of the Operational Support Center. Controlled access areas will be defined by the RMT personnel.
3.4.3 Extremely high radiation dose rates may be present during post-accident sampling.
These high dose rates could result in high radiation exposure. Performing this procedure requires ALARA pre-planning.
3.4.4 Emergency Sample Team will STOP and go to a low dose area (i.e. primary chemistry laboratory) if dose rates at re-entry work area exceeds limits specified in pre-job briefing.
3.4.5 All sampling actions are performed from the Main Control Board by Operations or from the Count Room unless specifically noted.
l CH-632 l Rev. 2 l Page 7 of 77
3.4.6 CAT-8 HI-HI level has the following interlocks:
- CAV-623 closes
- CAV-627 closes
- CAP-10 stops 3.4.7 Pressure > 175 psig at CA-89-PI may cause relief valves CAV-702 or CAV-491 to open. These relief valves open at approximately 200 psig.
3.4.8 Pressure > 30 psig at CA-94-PI may cause relief valve CAV-705 to open. This relief valve opens at approximately 50 psig.
3.4.9 Relief valves CAV-702, CAV-705, and CAV-491 discharge to the MWST. Lifting these relief valves may cause increased dose rates in the AB.
3.4.10 Sample is flushed through the boronometer at least 2 hours2.314815e-5 days <br />5.555556e-4 hours <br />3.306878e-6 weeks <br />7.61e-7 months <br /> before obtaining boron results.
3.4.11 Sampling described in Section 4.0 of this procedure CANNOT be performed concurrently due to shared piping in the different sample streams.
3.4.12 Sampling any of the low pressure systems for the first time requires an entry into the PASS room (95' AB) to reposition CAV-701 to PORT 2 which could result in high radiation exposure. CAV-701 is normally positioned to PORT 1. Once positioned to PORT 2, the valve will remain in that position to avoid re-entry into a potentially high dose area.
3.4.13 The RB sump ALTERNATE sample point returns water to the MWST which could result in increased radiation levels in the AB.
3.4.14 Using the RB sump ALTERNATE sample point requires an entry into 95' IB to open CAV-500 which could result in high radiation exposure. A second re-entry is required to close the valve when securing the line-up.

ASSESSMENT OF CORE DAMAGE BASED ON REACTOR COOLANT SAMPLE Assumptions and Limitations
- 1. Use of RCS sample results to estimate the extent of core damage is subject to significant uncertainties. Many orders of magnitude error are possible due to factors such as:
- fraction of an isotope assumed to be released from the fuel matrix
- homogeneity of the activity in the RCS
- whether or not sample is representative
- effects of removal mechanisms
- 2. Given the possible magnitude of the above errors, no corrections are made for the following minor factors:
- Radioactive decay (longer half-life nuclides chosen to minimize error)
- Dilution volume (assumes CFT's have discharged and BWST injection to low alarm setpoint)
- RCS temperature and density corrections
- Reactor power history (assumes end of cycle activities for long lived nuclides and assumes shorter lived nuclides at equilibrium)
- 3. Appropriate corrections may be applied if desired. For example, if no water has been added from the CFT's or BWST, then results could be reduced by a factor of 5.5 (510,000 lb RCS mass vs. 2,800,000 lb mass RCS, BWST and CFT's)
