Precautions 4.1.1 4.1.2 4.1.3 4.1.4 4.1.5 4.1.6 4.1.7
. 4.1.8 4.1.9 Only instrumentation specifically approved by the MARSAME Manager for surveying structures, systems, and M&E for unconditiJnal release shall be used when performing surveys in accordance with this procedure.
Only instrumentation capable of meeting the required MDCs shall be used to survey structures, systems, and miscellaneous M&E for unrestricted release.
Only qualified individuals may perform a URS of structures, systems, and miscellaneous M&E.
Structures, systems, and miscellaneous M&E designated for surveys and within the scope of this procedure shall be assessed for the possibility of internal contamination. This may involve disassembling or cutting access ports to gain access to internal surfaces/components. Prior to disassembling or cutting access ports, communications must be established with the appropriate Project Lead, Job Supervisor, and Zion Safety Department to ensure proper procedures are followed and the necessary support is available.
- Prior to any elevated work or confined space entries, discussions must be held with the appropriate Project Lead, Job Supervisor, and Zion Safety Department to ensure proper procedures are followed and the necessary support and permits are available.
Structures, systems, and miscellaneous M&E being surveyed that do not pass the release criteria may be (1) dismantled to isolate radioactive material and then resurveyed or (2) decontaminated and then resurveyed in an attempt to unconditionally release the structures, systems, and miscellaneous M&E. The scope of these actions will be determined by the survey planning team and added to the survey plan.
Survey data that exceeds the criteria or action levels used to determimtthat structures, systems, or M&E are suitable for release from radiological controls shall be reported to the RP-OPS Supervisor to ensure proper radiological controls, postings, and labels are implemented and maintained.
When surveying structures, systems, or M&E for unconditional release, the ambient background as measured by the instrumentation used must be known and/or controlled to ensure that the required MDCs are met. If necessary, consider relocating M&E to a lower background area or determine a local background by performing a shielded vs. unshielded background assessment.
Increase the count times, and/or using alternative instrumentation as approved by the MARSAME Manager.
All radiological markings (placards, labels, markings, rad tape, rad rope, etc.)
shall be removed or permanently defaced on all material and equipment to be released from radiological controls.
Page 8of47

This critical level is associated *with the appropriate minimum detectable concentrations (MDCs), after correcting for applicable background interferences, as necessary. If alternative criteria are used to determine if structures, systems, and miscellaneous M&E contain, or are contaminated with plant-related radioactivity, the criteria used shall be clearly documented as part of the survey plan/package documentation, and approved prior to initiating any related surveys, by the MARSAME Manager, or designee.
4.2.3 The associated MDCs for scan measurements and smears shall be no greater than the corresponding limits in NRC I.E. Circular No. 81-07.

1 Measurement Quality Objectives for Survey Plans Measurement Quality Objectives (MQOs)
ZS-L T-400-001-00.1 Revision 3 Information Use The following MQOs are established in order to ensure that the survey instrumentation used and survey and sampling methods performed will adequately and accurately characterize material surveyed for Unconditional Release based on a release limit of "no detectable".
The survey and sample analysis instrumentation selected for performing unconditional release ofmaterial, equipment and secondary structures from the ZSRP are consistent with the guidance found in NUREG-1575. The range, ruggedness, sensitivity, detection capability and quantification capability were confirmed through instrumentation calibration.
Implementation of instrument special training, operating procedures and survey plan instructions ensure that measurement method uncertainty remains consistent.
Selected Instrumentation Ludlum Model 2350 Data Logger coupled with detectors; 43-68 and 43-37 proportional detectors, 44-10 Nal.
Ludlum Model 2360 with 43-93 scintillator detectors.
Ludlum Model 3 with a 44-09 GM detector Ludlum Model 54 article monitor Ludlum 303.0P Alpha-Beta smear counter Tennelec S5 XLB proportional smear counter Canberra Lab SOCS/ISOCS Genie-2000 Gamma Spectroscopy System Canberra Inspector 1000 for qualification of indications of concern Background Determination Typically field background is determined as the mean of 5 background measurements
- collected as ambient area or as material specific background.
The equations below are listed in NUREG 1575, Rev. 1 page 6-34 as (6-6).
I The background mean and its associated standard deviation for the area where surveys will take place. Calculation of Le and Ld can be performed after arithmetic mean of background is obtained.
Le = 2.33.Jbkrd Ld = 3+( 4.65.Jbkrd)
Material specific background as above for material that has NORM.

- 1. PURPOSE AND SCOPE 1.1. Purpose This procedure provides the guidance used to design, perform, control, evaluate and document Contamination Verification Surveys (CVS) performed to verify that pre-open air demolition contamination levels of radiological impacted systems, structures and components (SS Cs) of the site Radiologically Controlled Area (RCA) and non-RCA are below the established limits for open air demolition. This procedure also provides guidance for authorization and implementation of isolation techniques and engineering controls to prevent airborne release or spread of contamination during removal of SSCs that exceed the open air demolition criteria.
1.2. Scope The performance of CV~ will ensure airborne radioactivity levels resulting from open air demolition are maintained within regulatory limits and that off-site dose consequences remain As Low as Reasonably Achievable (ALARA). It is_ assumed that Radiation Protection Operations (RP Ops) provide job coverage surveys during the course of demolition that will demonstrate that the radiological condition of a specific area is suitable for CVS.
Radiological conditions attributed to SSCs identified that exceed open air demolition criteria will limit the survey of adjacent SSC in some instances As agreed to by the Director of Radiation Protection SSCs exceeding open air demolition criteria will be removed, employing isolation techniques and engineering controls adequate to prevent release of airborne radioactivity and the spread of contamination during removal.
.Supplemental CVS survey will be performed in the area(s) not previously surveyed adjacent to SSCs and areas potentially contaminated by removal of SSCs. Open air demolition in the area will not continue until the supplemental CVS is completed and re~mlts satisfactory.
