NRC INSPECTION MANUAL ARCB INSPECTION PROCEDURE 83535 PART 52, CONTROL OF RADIOACTIVE MATERIALS AND CONTAMINATION, SURVEYS, AND MONITORING PROGRAM APPLICABILITY: IMC 2504 B 83535-01 INSPECTION OBJECTIVE 01.01 To inspect for readiness of the plant with respect to Title 10 of the Code of Federal Regulations (10 CFR) Part 20, Standards for Protection against Radiation, based on the licensees programs for control of radioactive materials, contamination, surveys, and monitoring.

01.02 To determine whether the programs for control of radioactive materials and contamination, and performance of surveys and monitoring are adequate to support the radiation protection program objectives, including normal operation and under abnormal or accident conditions. This inspection procedure focuses on the programs readiness for use by plant personnel and effects on the developed program. For program elements where an issue arises directly related to emergency preparedness (EP), refer to the applicable EP inspection procedure for follow-up.

83535-02 INSPECTION REQUIREMENTS AND GUIDANCE General Inspection Guidance If the unit being constructed is at a site with existing operational units for which the same program will be used at all units, then this program may not require the same level of inspection as that required for units being constructed at sites with no operational units. This is consistent with the Baseline Inspection Program requirements identified in Inspection Manual Chapter 2506, Construction Reactor Oversight Process General Guidance and Basis Document. At sites with an operating unit where the licensee has chosen to take credit for similar operational programs as those that are already in use, the inspectors shall focus on the differences between the program already in use and the newly developed program. The operational program inspection should focus on those steps in the IMC 2504 inspection procedures where the inspectors cannot verify that the operational program, equipment, and components are the same, or substantially similar to, that of the operating unit. If the operational program, equipment, and components are the same, or substantially similar to, the operating unit, then the following minimum inspection requirements shall be completed, and all other inspection requirements may be omitted:

Issue Date: 03/04/20 1 83535

10 CFR Part 52 Licensees Collocated with an Existing Operational Unit Minimum Inspection Requirements:

a. Verify that the 10 CFR Part 52 licensee has incorporated the operational plants procedures for Control of Radioactive Material, Contamination, Surveys, and Monitoring into their program.

b. Verify, on a sampling basis, that area radiation and airborne radioactivity monitors are installed, calibrated, and operable, using Section 02.03, Area Radiation and Airborne Radioactivity Monitors, as guidance (Walkdowns).

c. Verify that sufficient calibrated and operable portable survey instruments are available to evaluate expected radiological conditions, using Section 02.04, Portable Survey, Sampling, and Contamination Monitoring Instruments, as guidance (Walkdowns).

Inspection Guidance: Verification of procedure incorporation should include a review of procedure cover sheet information (e.g., procedure titles and site applicability, management approvals, and revision history, etc.), and a limited review of the procedure itself for applicability to the 10 CFR Part 52 site. The licensee may have developed specific procedures due to differences in plant design or layout. If so, review the site-specific design differences for conformance with the Final Safety Analysis Report (FSAR) and review procedures for adequate inclusion of the site-specific design differences. Applicable guidance can be found throughout IP 83535. Where applicable, review these inspection activities for compliance with 10 CFR Part 20, 10 CFR Part 52, and the FSAR.

02.01 Radioactive Material and Contamination Control. Determine whether provisions for control of radioactive materials and contamination meet requirements as described in the licensees FSAR are adequate. Key aspects of the Radiation Protection program, such as facilities, instrumentation and equipment, training, and procedures are implemented by the radiation protection program procedures, similar to those described in Nuclear Energy Institute (NEI)07-03A, Generic FSAR Template Guidance for Radiation Protection Program Description. NEI 07-03A describes a radiation protection program that will be implemented in stages consistent with the following milestones:

a. Prior to initial receipt of by-product, source, or special nuclear materials (excluding Exempt Quantities as described in 10 CFR 30.18).

b. Prior to receiving reactor fuel.

c. Prior to initial load of fuel.

d. Prior to initial transfer, transport, or disposal of radioactive materials.

Licensee capability and performance in this area is evaluated on the basis of whether the licensee has taken appropriate measures to establish and maintain the program. Some aspects of a complete program, such as calibration of equipment, are not fully described in full in NEI 07-03A, and should be evaluated based on current guidance and the program developed by the licensee.

Issue Date: 03/04/20 2 83535

For those licensees that elect to demonstrate compliance with the requirements of 10 CFR Part 20 via alternate methods, SECY-04-0032, Programmatic Information Needed for Approval of a Combined License Application Without Inspections, Tests, Analyses, and Acceptance Criteria addresses the absence of ITAAC, wherein the term fully described should be understood to mean that the program is clearly and sufficiently described in terms of the scope and level of detail that will support a reasonable assurance finding of acceptability at the combined license (COL) stage.

In addition, 10 CFR 20.1501(b) requires that instruments used for radiation measurements be periodically calibrated. However, while NEI 07-03A discusses instrument calibration, it does not specifically address the process to be used to ensure that calibration of portable and laboratory instruments is performed using known standards (i.e., traceability to the National Institute of Standards and Technology (NIST) or equivalent international standards). Since NEI 07-03 does not specifically address methods for establishing reference values for calibration standards or the methods for establishing calibration intervals, the licensees program should describe those program elements related to establishing traceability of calibration sources for portable and laboratory radiation protection instruments to recognized national or international standards, and the basis of the method for setting instrument calibration intervals, to ensure consistency with national standards and regulatory requirements in effect.

Focus should be on the ability to implement the applicable portions of the program for controlling radioactive materials and contamination, with additional emphasis on contamination minimization per 10 CFR 20.1406. The following aspects should be evaluated:

a. Documented plans and procedures should describe the system and responsibilities for identification, accountability, control, movement, storage, and inventory of radioactive materials outside of controlled areas; for identification, control, movement, and storage within controlled areas; for receipt of radioactive material; and criteria for release and unrestricted use in uncontrolled areas of materials from contaminated areas.

b. Provisions should be made for proper work techniques for contamination control and prompt correction and cleanup of contamination.

c. Provisions for minimizing the introduction of uncontaminated materials into contaminated areas.

d. Contamination control as a measure of the effectiveness of health physics, maintenance, and operations programs.

e. Provisions to detect, control, and promptly control and repair leaks in radioactive systems.

02.02 In-Plant Surveys and Monitoring. Determine whether provisions for surveys and monitoring of radiation and radioactivity meet requirements as described in the controlling documents and are adequate.

a. This inspection requirement is primarily limited to surveys and monitoring used to evaluate potential occupational exposure. Surveys for radiation exposure rate, airborne radioactivity, radioactive contamination, and radioactive materials are included. Internal and external exposure monitoring and assessment (dosimetry and bioassay programs) are further addressed in Inspection Procedures 83533 and 83534, respectively.

Issue Date: 03/04/20 3 83535

b. Procedures, or other survey program documents, should describe:

1. Frequency of periodic surveys, including criteria for conducting special surveys.

2 Nature and extent of surveys, including equipment to be used and suitable instrument types.

3. Reviews of surveys and uses of survey data in work planning and procedures, including administrative controls over work involving radiation and radioactive materials, such as radiation work permits, As low as Reasonably Achievable (ALARA) plans, and tag-out processes.

4. Identification, investigation, evaluation, and correction of abnormal or negative performance trends in radiological conditions.

5. Health physics supervision or management review of survey results.

6. Contamination surveys should address prevention and detection of the spread of contamination, such as:

(a) Checks for contamination of individuals using procedures and equipment that provides acceptable detection levels.

(b) Adequate detection of contaminated or activated materials before release for unrestricted use (see Generic Communications listed in Section 83535-04 References below).

(c) Surveys of waste areas not designated for radioactive materials, salvage areas, storage areas, etc.

7. Processes have been established to periodically evaluate and assess areas of the plant to ensure that personnel exposure to transuranic isotopes are anticipated and controlled (i.e., alpha monitoring program).

02.03 Area Radiation and Airborne Radioactivity Monitors. Determine whether area radiation and airborne radioactivity monitors for normal and emergency operations are installed as described in the application and in NUREG-0737, Item II.F.1, Attachment 3, and that adequate procedures have been developed for calibration, performance checks, maintenance, and use.

Aspects of protective equipment and monitoring programs that should be examined include:

a. For area radiation monitors, factors that should be examined include:

1. Conformance with the guidance of ANSI/ANS-HPSSC-6.8.1 (for monitoring and normal operations), of Regulatory Guide 1.97 (for accident monitors), and of NUREG-0737, Item II. F.1, Attachment 3 (containment high-range radiation monitor).

4. Personnel should be trained in proper use of instruments and be aware of their locations.

Issue Date: 03/04/20 6 83535

d. The references pertaining to test and calibration of survey and monitoring instruments should be reviewed to determine appropriate standards and performance criteria.

1. Determine the adequacy of the processes used to establish the initial radiation detection counting efficiency values and the evaluation processes for verifying and adjusting counting efficiencies, as needed, during initial testing and power ascension.

2. Determine that portable instruments provided to monitor radiation and airborne radioactivity concentrations in the facility and the site environs where it is impractical to install stationary monitors capable of covering both normal and accident levels, and are appropriately classified in accordance with RG 1.97 and IEEE-497.

e. Determine the effectiveness of the processes and procedures used to specify, acquire and use instruments and equipment, in a manner that is consistent with actual or expected site environmental conditions. Examples of environmental conditions which may impact the use or storage conditions of equipment include outside air temperature impact on dew point requirements for air cylinders stored in outside emergency vehicles, or temperature and pressure conditions expected inside the reactor containment building during power operation.

f. Determine the effectiveness of processes provided for evaluating routine equipment performance checks (e.g., daily source checks) and for ensuring regulatory compliance (i.e., adequate personnel protection per 10 CFR Part 20, or compliance with transportation limits) in the event of equipment failures.

Issue Date: 03/04/20 7 83535

c. Sufficient supplies should be readily available and accessible for both normal and emergency operations. See NUREG-0654, Planning Standards H and J, for emergency operations.

d. Determine the program elements and procedures associated with evaluating decontamination options and the impact on personnel heat stress exposure due to the use of protective clothing or respiratory protection devices.

e. Assess the effectiveness of site procedures for:

1. Implementation of design elements provided for radioactive material control.

2. Identifying, assessing and implementing current industry practices associated with radioactive material control.

3. Examining how performance indicators have been established, based on expected plant operations involving fuel receipt, fuel loading and initial startup testing.

02.06 Programs. Determine the licensees actions to address and properly document development of the program from the functional program description provided to NRC staff during the application review process. Focus is on readiness for operation.

Review the originating documents submitted by the licensee to determine the affected facilities and equipment:

a Review Agency resources to locate the most current versions of the applicable documents and functional program description.

b. Determine the specific measurements that will be needed to verify the readiness and acceptability of the program as implemented, in comparison with the program description provided in the application. Review inspections of other licensees of similar design. If there are ongoing issues at plants of similar design, consider the applicability of those issues in developing the scope of the inspection.

c. Determine from the licensees submissions regarding what commitments to or incorporation by reference were made with respect to national standards or other guidance documents, and whether there have been any changes, amendment proposals, impact evaluations, or other remedial or compensatory actions by the licensee that affect adequacy of the program, or that have not already been reviewed by NRC staff.

83535-03 RESOURCE ESTIMATE The staff estimates that approximately 40 hours4.62963e-4 days <br />0.0111 hours <br />6.613757e-5 weeks <br />1.522e-5 months <br /> of direct inspection effort will be required to implement this procedure. An inspection of the program and related procedures and records will require health physicists trained in applicable radiation protection procedures and inspection techniques as they relate to nuclear power facilities.

Issue Date: 03/04/20 8 83535

The actual hours required to complete the inspection may vary from this estimate. The inspection hours allocated for this inspection are an estimate for budgeting purposes. The hours expended for this inspection should consider plant specific design features and operational programs. The level of effort expended in such inspections should be recorded for the purpose of planning future inspections and updating budget allocations. If this inspection procedure is performed at a 10 CFR Part 52 licensee collocated with an existing operational unit and the operational program, equipment, and components are the same, or substantially similar to, that of the operating unit, inspection effort is expected to require approximately 20 hours2.314815e-4 days <br />0.00556 hours <br />3.306878e-5 weeks <br />7.61e-6 months <br /> of direct inspection effort.
