1. PURPOSE AND SCOPE 1.1. Purpose This procedure defines the turnover, isolation and control process for areas being released for the Final Radiation Survey (FRS) of structures, systems and open land areas after planned decommissioning activities are completed at Zion Station Restoration Project (ZSRP). It also provides the administrative process to evaluate, approve, and document decommissioning or maintenance related activities in areas during and following FRS activities.

Because of differences in the conceptual models and required source terms, the FRS includes two different approaches depending on the media; (1) Final Status Survey (FSS) is conducted on soil, buried piping and groundwater to demonstrate that residual radionuclide concentrations are equal to or below site-specific Derived Concentration Guideline Levels (DCGL), and (2) a Source Term Survey (STS) is conducted to demonstrate that the inventory of residual radioactivity in building basements, embedded piping and penetrations is below a source term inventory commensurate with the dose criterion in 10 CFR 20.1402.

The term FRS is used in this procedure to represent both the FSS and STS surveys.

When only one of the survey methods is being addressed, either FSS or STS is specifically referenced.

Survey area, as addressed in this procedure, can include one or several survey units.

1.2. Scope Planned decommissioning actions must be completed and assessed for isolation and control measures before FRS activities can begin in a designated area. This procedure describes the protocols used to verify and document that an area is in suitable physical condition for FRS implementation and proper isolation and control measures are in place to limit the potential for cross-contamination from other decommissioning activities and to maintain the final configuration of the area.

This procedure applies to all personnel performing turnover and control activities in support of FRS.

4. PRECAUTIONS, LIMITATIONS, AND PREREREQUISITES 4.1. Precautions 4.1.1 Isolation and control measures are implemented to ensure that the final radiological and physical condition of a FRS survey area is not compromised and/or re-contaminated from access by personnel or equipment, or impacted by on-going decommissioning activities.

ZS-LT-300-001-003 Revision 2 Information Use Page 7 of 21 4.1.2 FRS survey area(s) shall be posted with signs instructing individuals to contact the Site Characterization/License Termination group prior to entering or conducting work activities in the area.

4.1.3 Scan surveys performed for area turnover should focus on sections which had been contaminated, remediated, or have been in direct contact with radioactive materials.

4.1.4 When a land area has been turned over for FRS, no radioactive material shall be introduced and/or demolition activities allowed.

4.2. Limitations 4.2.1 A systematic approach to the turnover of areas should be established, which could include a back-out plan and/or schedule. Planning the sequence of area turnover ensures the logistics to perform remediation activities does not impact the radiological status of a FRS survey unit.

4.2.2 Isolation and control measures shall be established for each survey area. Several survey areas of a common type may be grouped for isolation and control purposes.

4.2.3 Isolation and control measures shall remain in force until there is no risk of re-contamination from decommissioning activities or the survey area is released from the license.

4.3. Prerequisites 4.3.1 Controls and preparation for FRS shall be based on characterization and/or RA/RASS results that indicate residual radioactivity is unlikely to exceed an applicable action level, dose criterion, or Derived Concentration Guideline Level (DCGL).

4.3.2 Decommissioning activities having the potential to contaminate the survey area must be completed prior to the initiation of turnover activities.

4.3.3 Tools and equipment not required to perform FRS must be removed from the survey area prior to turnover. Any tools and equipment that remain in the area shall be surveyed for unrestricted release.

4.3.4 Housekeeping and cleanup of the survey unit must be completed prior to the initiation of turnover activities.

4.3.5 Posting materials used for posting of survey area(s) should be easily recognizable as pertaining to FRS. Examples of these materials are green protective coverings such as tarps, herculite and/or plastic, labels, ropes and signs. Postings and signs used to denote radiologically controlled areas shall not be used. An example of a sign used for posting a FRS area is provided in Attachment 4.

ZS-LT-300-001-003 Revision 2 Information Use Page 8 of 21

5. MAIN BODY NOTE Other formats may be used to document survey area turnover provided that the same information is presented as in the Attachments.

5.1. Initiate Isolation and Control Measures NOTE Upon completion of commodity removal, decontamination and/or demolition activities in a designated FRS survey unit, the Site Characterization/License Termination group shall be notified that the decommissioning activities in the survey unit(s) are complete and the area is ready for FRS. This communication may occur formally, (e.g., by schedule, memorandum or through project controls) or in-formally (e.g., by verbal communication). Verification of decommissioning completeness is provided by the turnover process.

5.1.1 When a survey area is deemed ready for FRS, then initiate Attachment 1, Area Turnover and Control Checklist for the survey unit and document the following information: (C/FRS Supervisor)

(RE or C/FRS Supervisor)

ZS-LT-300-001-003 Revision 2 Information Use Page 11 of 21 5.3. Area Turnover Survey and Posting NOTE The RE may waive the performance of an area turnover survey if the results from previous surveys (operational, characterization, RA, RASS) indicate a low probability that the survey area contains residual contamination above the applicable action level or DCGL and, the survey area was not remediated prior to the performance of FRS.

5.3.1 Review characterization and/or RA/RASS sample data for the survey area to determine if sufficient data is available to perform FRS survey design. (RE) 5.3.2 Indicate on Attachment 1 whether a survey is required for turnover, and if yes, provide the RA/RASS Sample Plan number. (RE)

NOTE The same type of instrumentation and instrument sensitivity that will be used for FRS should be used to assess a survey area and/or survey unit for turnover.

Instrumentation shall be controlled and operated in accordance with approved procedures and ZS-LT-01, Quality Assurance Project Plan (QAPP) for Characterization and Final Radiation Survey (Reference 6.2). Use of alternate instrumentation shall be approved by the responsible RE.

1.)

If the existing radiological survey data is adequate and sufficient for FRS survey design, then the survey performed for area turnover should consist of biased scans only.

2.)

If inadequate data is available, or if the variability in the existing data is excessive, then the responsible RE shall design a RA/RASS survey in accordance with procedure ZS-LT-200-001-001, Radiological Assessments and Remedial Action Support Surveys (RASS) (Reference 6.3) to acquire the measurements or samples (e.g., direct measurements, surface soil samples, etc...) necessary for the survey design for FRS.

5.3.3 Sign and date Attachment 1 under Survey for Area Turnover. (RE) 5.3.4 When directed, perform a turnover survey of the area using the instructions provided in the RA/RASS sample plan per the following: (C/FRS Technicians) 1.)

Document the turnover survey results on a survey map.

2.)

If the instrument alarms while performing the scan survey, then verify the alarm is valid by repeating the scan of the area in question.

A.

If the alarm is confirmed, then document all alarm locations and results on the survey map.

B.

If the alarm cannot be confirmed, then no further action is required.

ZS-LT-300-001-003 Revision 2 Information Use Page 12 of 21 5.3.5 Sign the Survey for Area Turnover section of Attachment 1, attach the results of the RA/RASS, including survey maps and data, and forward to the responsible RE. (C/FRS Technicians) 5.3.6 Review the RA/RASS results. (RE) 1.)

Document any Comments and Observations in the applicable section of.

2.)

If the survey area is acceptable for FRS, then denote approval by signing under the Comments and Observations section of the Attachment 1 and instruct the C/FRS Supervisor to post the survey area.

3.)

If the survey area is not acceptable for FRS, then cease the turnover process and inform the Vice-President D&D/Construction that the area requires additional remediation.

4.)

If the turnover process is terminated because additional remediation is required, then discard the current Attachment 1 and initiate a new Attachment 1 when the survey area is ready to be re-evaluated.

NOTE Designated FRS areas should have controls and postings placed at all entrances.

Postings should be highly visible to notify personnel of access restrictions and requirements.

5.3.7 Document the controls implemented in the Posting and Controls section of. (C/FRS Supervisor) 5.3.8 Post FRS areas using signs such as illustrated in Attachment 4, and establish controls as directed by the C/FRS Supervisor. (C/FRS Technicians)

NOTE Posting the area is the minimum requirement for isolation and controls. Other controls include physical restrictions such as stanchions and barricades; use of personnel frisking stations, sticky pads, protective clothing to prevent the introduction of plant-related radioactivity into the area; personnel training, briefing and site wide notices to disseminate information and provide instruction; or any combination of the above. These measures should be considered commensurate with the potential for introducing plant-related radioactivity into the area.

5.3.9 File the completed Attachment 1 in the appropriate survey package.

ZS-LT-300-001-003 Revision 2 Information Use Page 13 of 21 5.4. Access Control NOTE While it is highly desirable to control access to survey areas as soon as possible following completion of decommissioning activities, it is absolutely essential that access be positively controlled at the time of, and following, the performance of a RA/RASS survey performed for the purpose of area turnover.

5.4.1 Entry of personnel and/or equipment into areas that have been turned-over and are controlled for unrestricted release and/or FRS will be restricted.

NOTE Most approvals are provided daily or on a case-by-case basis. A generic, one-time approval for access may be granted by the C/LT Supervisor if the potential for introducing plant-related radioactivity is low. An example would be Security performing routine inspections.

1.)

Personnel shall receive authorization from the C/FRS Supervisor prior to entering these areas.

2.)

Personnel entering or exiting an area controlled for FRS purposes shall sign in and sign out on a FRS Area Access Sign-In Sheet, Attachment 3.

3.)

All personnel, tools and equipment shall be surveyed for the presence of residual radioactive material and/or contamination prior to entering these areas.

Exceptions to the survey requirement will be approved by the C/FRS Supervisor.

5.4.2 Any work activities to be performed in areas that have been turned-over and are controlled for FRS will require prior review and approval by the C/FRS Supervisor.

1.)

Document the evaluation of access work requests and approval or denial using a log book or other tracking mechanism. (C/FRS Supervisor) 2.)

Document the date of request for access or evaluation, the name, company and telephone number of the contact person, the work to be performed and the expected duration. (C/FRS Supervisor) 3.)

Summarize the conclusions of the assessment to determine if there is any potential impact from the introduction of plant-related radioactivity into the area and, if any actions must be taken to prevent re-contamination (e.g., engineering controls, approval/denial of access). (C/FRS Supervisor)

ZS-LT-300-001-003 Revision 2 Information Use Page 14 of 21 5.4.3 Access control and boundary controls/signage shall be removed from STS areas just prior to backfill. The backfilled area has a very low risk of re-contamination and will revert to an open land area for future FRS evaluation.

5.5. Post FSS Routine & Special Surveillances 5.5.1 Generate and maintain a list of survey units that have completed FRS and require surveillance. (C/FRS Supervisors)

NOTE Routine surveillances will be performed in areas following FRS completion to monitor for indications of recontamination and verification of postings and access control measures.

NOTE Surveillances are not required in STS survey units that have been backfilled or in piping (embedded or buried) that has been isolated or grouted in place.

5.5.2 Perform a routine surveillance of each FRS area on a semi-annual basis. In addition, a surveillance may be performed at any time as determined by the responsible RE when an activity occurs that may have radiologically impacted the survey unit (e.g., transiting a radioactive material package though an FRS area, etc). Perform surveillances as follows:

1.)

Review the authorizations and reasons for entry into the area since the performance of FRS or the last surveillance.

2.)

Perform a walk-down of the area checking for proper postings, barriers, system covers, and/or seals, as appropriate, are intact and, for evidence of disturbance, loss of isolation and control or unauthorized introduction of or placement of radioactive materials.

3.)

Document the verification on a survey map(s) of the area(s).

NOTE The Canberra In-Situ Object Counting System (ISOCS) has been selected as the primary instrument that will be used to perform STS. Consequently, the ISOCS will also be used in the same manner to perform any required surveillance in a STS survey unit. Scanning is not applicable to a STS survey unit.

4.)

If the results from steps 1 and 2 are not satisfactory, then perform and document a biased scan of the survey area, focusing on access and egress points and any areas of disturbance and/or concern using the same type of instrument and detector, scan speed, and alarm set-points as used in the original survey.

ZS-LT-300-001-003 Revision 2 Information Use Page 15 of 21 5.)

Forward the completed surveillances of FRS areas to the RE for review and approval.

5.5.3 If a routine surveillance identifies physical observations and/or radiological scan measurements that require further investigation, then FRS may be repeated in the affected survey unit at the discretion of the RE or C/LT Manager.

5.5.4 If FRS is repeated in a survey unit, then generate a new sample plan in accordance with ZS-LT-300-001-001, Final Radiation Survey Package Development (Reference 6.1).
