The RANGE system samples the RB atmosphere and gaseous effluents from both the RB and AB Vents.
The RANGE system consists of an AIMS detector to perform gamma isotopic analysis of the sample streams.
The RANGE system provides the ability to obtain gaseous and radioiodine grab samples to be shipped off-site for analysis.
The RANGE system has the ability to continuously monitor gaseous effluents from the RB and AB vents via the mid-and high-range noble gas monitors. The RB and AB each have a LMH valve controller that automatically aligns the mid-and high-range noble gas monitors based on sample stream activity. The LMH valve controllers may be operated manually.
When estimating total activity for gaseous 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

3.1.6 When estimating total activity for particulate and iodine grab sample shipment the following assumptions are 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. Pig is 5.625 inches tall with diameter of 5.5 inches.
The pig is composed of 0.5" lead and.375" of iron. The RMSB filter canister is 1.375" tall with a diameter of 2.25". The measurement distance is 3.0 " from the center of the pig.
Release fractions from Regulatory Guide 1.183 for gap and early in-vessel melt No removal of iodines and particulates from RB or AB air
- The RB or AB atmospheric mix is on the particulate and iodine filter. The particulate and iodine is filtered by the HEPA and charcoal banks, but the isotopic mix remains unchanged. Some of the Xe and Kr gas is retained in the iodine cartridge. The RB or AB particulate and iodine is reduced by - 99%
through the filters, and approximately 1 % of gas is retained in the cartridge.

OSC Chemistry Coordinator or designee 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 This procedure is performed by a qualified Emergency Sample Team member.
Limits and Precautions Any or all of this procedure is done by direction of the EC or designee.
Re-entry must have RMT preplanning, concurrence, and coverage as outlined in EM-1 04, Operation of the Operational Support Center. Controlled access areas will be defined by the RMT personnel.
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.
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.
All sampling actions are performed from the Main Control Board by Operations or from the Count Room unless specifically noted.

3.4.6 WS-1 3-CE (RANGE AIMS) can measure 1.OE-6 Ci/cc to 1 OE+5 Ci/cc.
3.4.7 WSP-1 is a positive displacement pump and may be damaged if operated without complete or proper valve line-up.
3.4.8 WSV-70 is interlocked with the following valves and will not open if any of these valves are open.
WSV-33 WSV-35 WSV-36 WSV-37 3.4.9 RMV-25 does not have a separate operator. It is interlocked with RMV-8. When RMV-8 is closed, RMV-25 will open. When RMV-8 is opened, RMV-25 will close.
3.4.10 RMV-26 does not have a separate operator. It is interlocked with RMV-20. When RMV-20 is closed, RMV-26 will open. When RMV-20 is opened, RMV-26 will close.
3.4.11 RMV-6 is a 3-way valve. OPEN indicates RMV-6 is aligned from RM-A1-RE4 (RM-A1 gaseous mid-range detector) outlet to RB Exhaust Duct.
CLOSED indicates RMV-6 is aligned from RM-A1 -RE4 (RM-A1 gaseous mid-range detector) outlet to RMP-A1 (RM-A1 sample pump) inlet.
3.4.12 RMV-18 is a 3-way valve. OPEN indicates RMV-18 is aligned from RM-A2-RE4 (RM-A2 gaseous mid-range detector) outlet to AB Exhaust Duct. CLOSED indicates RMV-18 is aligned from RM-A2-RE4 (RM-A2 gaseous mid-range detector) outlet to RMP-A2 (RM-A2 sample pump) inlet.
3.4.13 RM-A1-Fl and RM-A2-FI readings are multiplied by 0.1 to obtain flow in cfm.
3.4.14 A maximum filter loading of 3 Ci total activity is recommended for particulate and iodine filter grab samples.
3.4.15 RB dome sampling via WSV-34 and WSV-35 is the preferred sample point for sampling the RB atmosphere.
3.4.16 RB emergency recirculation discharge duct sampling via WSV-32 and WSV-33 is the preferred alternate sample point for sampling the RB atmosphere.
3.4.17 RB normal recirculation duct sampling via WSV-3 and WSV-4 is the least preferred sample point for sampling the RB atmosphere because this ventilation duct is normally secured during accident conditions.
3.4.18 ES must be bypassed or reset by Operations before WSV-3, 4, 5 or 6 can be opened from the Control Room.
3.4.19 Sampling described in Section 4.0 of this procedure CANNOT be performed concurrently due to shared piping in the different sample streams.

Manual Collimator Positioning and Manual Gamma Isotopic Analysis NOTE Starting with FAR CLOSED and progressively trying more efficient geometries is recommended but not required.
- 1. POSITION collimator and near line valves per Table 2 until one of the following criteria is met:
- adequate count rate observed at WS-1 3-CE rate meter
- NEAR OPEN position lined up with adequate count rate
- OSC Chemistry Coordinator or designee determines geometry to be used
- 2. Manually perform gamma spectroscopy analysis.

NOTE The collimator position lights represent binary code. The 1, 2, and 3 lights may be disregarded when manually positioning the collimator. These lights represent a total of 7 binary units which is <1 0% of total collimator movement.
