FINAL SUPPORTING STATEMENT FOR 10 CFR PART 50 STANDARDS FOR LICENSES, CERTIFICATIONS AND REGULATORY APPROVALS SECTION 7 (50.44(c), Hydrogen Control Requirements; Appendix K, 50.46, Acceptance Criteria for Emergency Core Cooling Systems (ECCS);
50.47, 50.54(q & t), Appendix E, Emergency Planning; 50.48, Appendix R, Fire Protection; 50.49, Environmental Qualification; 50.120, Training & Qualification of Nuclear Power Plant Personnel; Appendix J, Primary Reactor Containment Leakage Testing For Water-Cooled Power Reactors; Appendix S, 50.54(ff), Earthquake Engineering Criteria for Nuclear Power Plants) 3150-0011 ABSTRACT Title 10 of the Code of Federal Regulations (10 CFR), Part 50 contains the Nuclear Regulatory Commissions (NRC) requirements and provisions for Standards for Licenses, Certifications and Regulatory Approvals.
The U.S. Nuclear Regulatory Commission (NRC) is authorized by Congress to have responsibility and authority for the licensing and regulation of nuclear power plants, research/test facilities, fuel reprocessing plants and other utilization and production facilities licensed pursuant to the Act. To meet its responsibilities, the NRC conducts a detailed review of all applications for licenses to construct and operate such facilities. The purpose of the detailed review is to ensure that the proposed facilities can be built and operated safely at the proposed locations, and that all structures, systems and components important to safety will be designed to withstand the effects of postulated accident conditions, without undue risk to the health and safety of the public.
Under 10 CFR Part 50, before a company can build a nuclear power plant at a particular site, it must obtain a construction permit from the NRC. Subsequently, the company must obtain an operating license from the NRC before it can operate the plant. The decision by the NRC as to whether to approve a company's application for a construction permit or an operating license is based largely on the NRC staff's detailed review of the information provided by the company as part of its application. Information provided by the applicant as part of the application is crucial to the licensing process as it provides the NRC with the information it needs to make a decision with regard to the proposed plant's impact on the public's health and safety and the environment.
These regulations affect 89 licensees for operating nuclear power plants, 31 non-power production and utilization facilities, 15 combined operating license holders/applicants and 29 power plants that are currently being decommissioned. Licensees may voluntarily submit a request for an exemption to the Commission and maintain a record of that request. Licensees must perform certain tasks, maintain records and prepare reports to demonstrate their fulfillment of regulatory requirements. The reporting and recordkeeping requirements pertain to hydrogen control analyses; licensee emergency preparedness plans; fire protection plans; records documenting drills and training records for each fire brigade member; list of electric equipment important to
safety; documents related to the establishment, implementation and maintenance of the training and qualification of nuclear power plant personnel; pre-operational and periodic tests must be documented in a readily available summary report and made available for inspection upon request at the nuclear power plant.
This section incorporates the Mitigation of Beyond Design Basis Events (MBDBE) Final Rule, which was approved by OMB August 2019.
A. JUSTIFICATION
- 1. Need for the Collection of Information The information is needed in order to determine licensee compliance with the regulations set forth in CFR 50.44c; 50.46; 50.47; 50.54(q & t). 50.48; 50.49; 50.120 and Appendix S, 50.54(ff). Details of these regulations can be found at the end of this supporting statement in Appendix A, Description of Requirements.
- 2. Agency Use of Information Applicants or licensees requesting approval to construct or operate utilization or production facilities are required by the Atomic Energy Act of 1954, as amended (the Act), to provide information and data that the NRC may determine necessary to ensure the health and safety of the public.
The NRC uses the records and reports required in this part to ascertain that licensees licensing the design, construction, operation, and decommissioning of commercial nuclear power plants and other nuclear facilities programs are adequate to protect public health and minimize danger to life and property and that licensees personnel are aware of and follow up on the information and steps needed to perform licensed activities in a safe manner. The reports and recordkeeping requirements allow NRC to determine whether to take actions, such as to conduct inspections or to alert other licensees to prevent similar events that may have generic implications. The emergency plans provide reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency. The emergency preparedness information submitted by licensees enables the NRC to determine the adequacy of the emergency plan, in regard to compliance with the emergency preparedness regulations. This includes whether additional regulatory oversight is needed. The information is also used to update information in the NRC Emergency Operations Center used in support of an NRCs response to an actual emergency, drill, or exercise.
- 3. Reduction of Burden Through Information Technology There are no legal obstacles to reducing the burden associated with this information collection. The NRC encourages respondents to use information technology when it would be beneficial to them. The NRC has issued Guidance for Electronic Submissions to the NRC which provides direction for the electronic transmission and submittal of documents to the NRC. Electronic transmission and submittal of
documents can be accomplished via the following avenues: The Electronic Information Exchange (EIE) process, which is available from the NRC's Electronic Submittals Web page, by Optical Storage Media (OSM) (e.g. CD-ROM, DVD), by facsimile or by e-mail. It is estimated that approximately 90% of the responses are filed electronically.
- 4. Effort to Identify Duplication and Use Similar Information No sources of similar information are available. There is no duplication of requirements.
- 5. Effort to Reduce Small Business Burden The regulations cited previously affect both commercial power reactor licensees and non-power reactor licensees (e.g., research and test reactors operated by colleges and universities). Appendix E to 10 CFR Part 50 states that Regulatory Guide 2.61 will be used as guidance for the acceptability of research and test reactor emergency response plans. Regulatory Guide 2.6 endorses ANSI/ANS-15.16-1982.2 The American Nuclear Society revised ANSI/ANS-15.16-1982 on September 13, 2008, and the NRC is pursuing endorsement of ANSI/ANS-15.16-2008 with a revision to Regulatory Guide 2.6. In addition, NUREG-08493 addresses emergency plans for research and test reactors. Together, these documents present the non-power reactor emergency planning and preparedness requirements.
The emergency preparedness record keeping and reporting burden for non-power reactors is less than for power reactors, because the requirements are based on the potential risks associated with the specific reactor, and the corresponding need to protect the health and safety of the public and the environment. Non-power reactors are much smaller than power reactors, and as such, create a lesser risk from credible accidents.
- 6. Consequences to Federal Program or Policy Activities if the Collection is Not Conducted or is Conducted Less Frequently If the information is not collected, NRC will not be able to assess whether licensees are operating within the specific safety requirements applicable to the licensing and operating activities for existing nuclear power reactors and research and test reactors.
The information and required frequency from licensees that seek to licensee and operator nuclear power reactors and research and test reactors is essential to NRCs 1

determination of whether the applicant has adequate equipment, training, funds and experience throughout the life of the licensee to protect the public health and safety.
If the information were not collected, or collected less frequently, the NRC could be unaware for an extended period of time that an existing or revised emergency plan is no longer adequate to protect the health and safety of the public and the environment.
Without a timely review of information, changes to personnel, procedures, equipment, or facilities, or failure to maintain an effective emergency plan, could adversely affect emergency preparedness and response without the NRC imposing required corrective measures.
- 7. Circumstances which Justify Variation From OMB Guidelines A licensee must submit a report under 10 CFR 50.46(a)(3)(ii) within 30 days of discovering any significant change or error so that NRC is apprised of significant safety issues requiring immediate resolution.
Section 50.4(b)(5) requires that written communications for emergency plans and related submissions, the signed original must be sent to the NRC Document Control Desk, with one copy to the appropriate Regional Office, and one copy to the appropriate NRC Resident Inspector (if one has been assigned to the site of the facility). This is required because the NRC has both a headquarters and regional offices, and an NRC Resident Inspector located at the site.
Section 50.54(q)(6) requires that licensees retain their emergency plan and each change that reduces the effectiveness of the plan as a record until the Commission terminates the reactor license, which is initially issued for 40 years. Section 50.54(t) requires that the results and recommendations from emergency plan and emergency preparedness program reviews be retained for five years. This ensures that the plans will be maintained and will provide appropriate documentation that will support NRC review.
Licensees must retain the fire protection plan until the NRC terminates the license in order to ensure the health and safety of the public.
The records required by 10 CFR 50.49(d) and 10 CFR 50.49(j) are required to be maintained for the life of the component so that the NRC and the licensees can periodically assess and determine if equipment important to safety at nuclear power plants meets specified performance requirements.
Rather than requiring records to be routinely submitted to the NRC, 10 CFR 50.120 requires sufficient records to be maintained on-site to permit NRC verification of the adequacy of the programs. Pursuant to 10 CFR 50.71, program records are to be retained until termination of the license. Job performance qualifications are to be retained and maintained for each employee for the duration of employment. These record retention requirements result in an auditable trail for ensuring that training is developed, evaluated, and revised based on job performance requirements, and that power reactor personnel are qualified to perform their jobs.
Leakage test results, implementation plans, and records of the performance-based testing program must be kept for the operating lifetime of each nuclear plant for reference purposes.
- 8. Consultations Outside the NRC Opportunity for public comment on the information collection requirements for this clearance package was published in the Federal Register on February 19, 2021, (86 FR 10360). Additionally, NRC staff contacted five stakeholders via email. The stakeholders were new, operating and research and test reactor owner licensee representatives and interested stakeholders from Duke Energy Progress, LLC, Kairos Power, Southern Nuclear Operating Co., Washington State University and X-Energy.
The NRC received one out-of-scope comment as a result of the FRN. No additional responses or comments were received as a result of the FRN or the staffs direct solicitation of comment.
- 9. Payment or Gift to Respondents Not applicable.
- 10. Confidentiality of Information Confidential and proprietary information is protected in accordance with NRC regulations at 10 CFR 9.17(a) and 10 CFR 2.390(b).
- 11. Justification for Sensitive Questions This regulation does not request sensitive information.
- 12. Estimated Industry Burden and Burden Hour Cost Detailed burden estimates are included in the supplemental burden spreadsheet titled, Burden worksheet for Section 7, Standards for Licenses, Certifications and Regulatory Approvals.
Hours Responses Reporting 423,951 4,484 Recordkeeping 413,701 164 TOTAL 837,652 4,648 The total estimated cost for information collection requirements in this section is estimated to be 837,652 hours0.00755 days <br />0.181 hours <br />0.00108 weeks <br />2.48086e-4 months <br /> at a cost of $233,704,908 (837,652 hours0.00755 days <br />0.181 hours <br />0.00108 weeks <br />2.48086e-4 months <br /> x $279/hr).
Detailed burden estimates are included in the supplemental burden spreadsheet titled, Table 1 - Summary of Supporting Statements. The $279 hourly rate used in the burden estimates is based on the Nuclear Regulatory Commissions fee for hourly rates as noted in 10 CFR 170.20 Average cost per professional staff-hour. For more
information on the basis of this rate, see the Revision of Fee Schedules; Fee Recovery for Fiscal Year 2020 (85 FR 37250, June 19, 2020).
- 13. Estimate of Other Additional Costs The quantity of records to be maintained is roughly proportional to the recordkeeping burden and therefore can be used to calculate approximate records storage costs.
Based on the number of pages maintained for a typical clearance, the records storage cost has been determined to be equal to .0004 times the recordkeeping burden cost.
Therefore, the storage cost for this clearance is estimated to be $46,169 (413,701 recordkeeping hours x $279 x .0004).
- 14. Estimated Annualized Cost to the Federal Government The staff has developed estimates of annualized costs to the Federal Government related to the conduct of this collection of information. These estimates are based on staff experience and subject matter expertise and include the burden needed to review, analyze, and process the collected information and any relevant operational expenses.
The annualized estimated cost to the government is shown on the attached Summary Table. The annualized cost to the government is estimated to be $5,656,725 (20,275 staff hours x $279/hr) as shown on the attached Summary Table.
- 15. Reasons for Changes in Burden or Cost The burden and number of responses have changed as described in the tables below:
Burden change 2018 estimates Current Change submission Reporting 299,065.0 423,951 +124,886 Recordkeeping 409,758.2 413,701 +3,942.8 Third Party 0 0 0.00 Disclosure Total 708,823.2 837,652 +128,828.8 Change in Responses 2018 estimates Current Change submission Reporting 4593.70 4,484 -109.7 Recordkeeping 173.00 164 -9 Third Party 0.00 Disclosure 0.00 Total 4766.70 4,648 -118.7 The primary reason for the change in the burden estimates associated with these requirements is due to the one expected submission of an DC application as stated in the Overview, Section 1. This submission is subject to the requirements related to
Appendix S, and 50.54(ff) earthquake engineering criteria (DC applicant), this burden is estimated at 155,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> per applicant. Other minimal increase changes occurred in Appendix K requirements for Emergency Core Cooling Systems (ECCS),
to include all applicable licensees.
There was a minimal decrease related to Appendix S, and 50.54(ff) earthquake engineering criteria (Operating Reactors), through historical review, staff determined the expected responses could be reduced, resulting in a reduction of responses and 4,500 hours0.00579 days <br />0.139 hours <br />8.267196e-4 weeks <br />1.9025e-4 months <br /> of burden.
Recordkeeping decreases occurred primarily due to the number of licensees subject to these regulations, these reductions occurred in the areas of 50.44(c), 50.48, Appendix R, 50.49(d),(f),(j), Appendix S, and 50.54(ff) earthquake engineering criteria (Operating Reactors), 50.120(b) due to a reduction of sites and 50.48(c) where no additional licensees are expected to transition to this regulation. These minor reductions resulted in an overall reduction of 9 recordkeepers.
Recordkeeping decreased for one-time implementation requirements associated with 50.155(a)(1). This section imposed one-time recordkeeping burden to review procedures, programs, and plans to confirm that they are consistent with the rule requirements in the Mitigation of Beyond-Design-Basis Events final rule. Only 17 licensees are estimated to complete these requirements during the clearance period because 38 licensees are estimated to have completed these requirements. This resulted in a burden reduction of 11,970 hours0.0112 days <br />0.269 hours <br />0.0016 weeks <br />3.69085e-4 months <br />
- 16. Publication for Statistical Use The information being collected is not expected to be published for statistical use.
- 17. Reason for Not Displaying the Expiration Date The recordkeeping and reporting requirements for this information collection are associated with regulations and are not submitted on instruments such as forms or surveys. For this reason, there are no data instruments on which to display an OMB expiration date. Further, amending the regulatory text of the CFR to display information that, in an annual publication, could become obsolete would be unduly burdensome and too difficult to keep current.
- 18. Exceptions to the Certification Statement None.
B. COLLECTIONS OF INFORMATION EMPLOYING STATISTICAL METHODS Not applicable.
Appendix A - Description Requirements Mitigation of Beyond Design Basis Events (MBDBE) Final Rule, approved August 2019 Section 50.34(i) requires applicants for power reactor operating licenses to include plans for implementing the requirements in 10 CFR 50.155, Mitigation of Beyond-Design-Basis Events, including a schedule for achieving full compliance, a description of the integrated response capability, and the equipment and location of the equipment upon which the strategies rely. These requirements were established under Order EA-12-049 and licensees have already completed this requirement.
Section 50.155 requires licensees to review their previous compliance under Orders EA 049 and EA-12-051 against the MBDBE rule requirements to confirm their compliance with the MBDBE rule, as well as to make changes to procedures, programs, and plans to reference the new MBDBE rule requirements (rather than the Order requirements). Sites will incur a one-time recordkeeping burden to review procedures, programs, and plans to confirm that they are consistent with the rule requirements.
Section 50.155(b)(1) requires licensees to develop strategies and guidelines to mitigate beyond-design-basis external events from natural phenomena that are developed assuming a loss of all ac power concurrent with either a loss of normal access to the ultimate heat sink or loss of normal access to the normal heat sink. These requirements were established under Order EA-12-049 and licensees have already completed this requirement.
Section 50.155(b)(2) requires licensees to develop strategies and guidelines to maintain or restore core cooling, containment, and spent fuel pool cooling capabilities under the circumstances associated with loss of large areas of the plant impacted by the event, due to explosions or fire. These requirements were established under Order EA-02-026 and licensees already comply with this requirement.
Section 50.155(f) requires licensees to maintain documentation of changes in the implementation of the requirements of section 50.155. These requirements were established under Order EA-12-049.
Standards for Licenses, Certifications and Regulatory Approvals SECTION VI- (50.44(c), Hydrogen Control Requirements:
10 CFR 50.44(b)(1), (2), (3), and (4)- contain requirements for a mixed atmosphere, combustible gas control, equipment survivability, and monitoring of hydrogen and oxygen concentrations during an accident, for currently-licensed reactors. Further, 10 CFR 50.44(b)(5) requires each current holder of an operating license for a boiling water reactor (BWR) with a Mark III-type of containment or for a pressurized water reactor (PWR) with an ice condenser-type of containment to perform certain detailed analyses regarding hydrogen control, structural capability, and equipment survivability. However, as noted above, all of the requirements have already been met for currently-licensed reactors.
10 CFR 50.44(c)- requires future water-cooled reactor applicants and licensees to:
(1) Mixed Atmosphere: Have a mixed atmosphere during accidents; (2) Combustible Gas Control: Either have an inerted atmosphere or limit hydrogen concentrations in containment during and following an accident that releases an equivalent amount of hydrogen as would be generated from a 100 percent fuel clad-coolant reaction, uniformly distributed, to less than 10 percent (by volume) and maintain containment structural integrity and appropriate accident mitigating features.
(3) Equipment Survivability: Containments that do not rely upon an inerted atmosphere to control combustible gases must be able to establish and maintain safe shutdown and containment structural integrity with systems and components capable of performing their functions during and after exposure to the environmental conditions created by the burning of hydrogen. Environmental conditions caused by local detonations of hydrogen must also be included, unless such detonations can be shown unlikely to occur. The amount of hydrogen to be considered must be equivalent to that generated from a fuel clad-coolant reaction involving 100 percent of the fuel cladding surrounding the active fuel region.
(4) Monitoring: Equipment must be provided for monitoring oxygen in containments that use an inerted atmosphere for combustible gas control, and for monitoring hydrogen in all containments. Equipment for monitoring oxygen and hydrogen must be functional, reliable, and capable of continuously measuring the concentration of the monitored gas in the containment atmosphere following a significant beyond-design-basis accident for combustible gas control and accident management, including emergency planning.
(5) Structural Analysis: An applicant must perform an analysis that demonstrates containment structural integrity. This demonstration must use an analytical technique that is accepted by the NRC and include sufficient supporting justification to show that the technique describes the containment response to the structural loads involved. The analysis must address an accident that releases hydrogen generated from 100 percent fuel clad-coolant reaction accompanied by hydrogen burning. Systems necessary to ensure containment integrity must also be demonstrated to perform their function under these conditions.
10 CFR 50.44(d)- requires future non-water-cooled reactor applicants and licensees and certain future water-cooled reactor applicants and licensees to provide:
(1) Information addressing whether accidents involving combustible gases are technically relevant for their design; and, (2) If accidents involving combustible gases are found to be technically relevant, information (including a design-specific probabilistic risk assessment) demonstrating that the safety impacts of combustible gases during design-basis and significant beyond-design-basis accidents have been addressed to ensure adequate protection of public health and safety and common defense and security.
SECTION VII- Appendix K, 50.46, ECCS 10 CFR 50.46- provides an alternate method of meeting the 10 CFR 50 Appendix K requirements for Emergency Core Cooling Systems (ECCS). It permits licensees or applicants to analyze ECCS performance using realistic calculations. This method of calculation may remove some operating restrictions and, thus, motivate licensees to submit realistic analyses for review. This aspect of the rule represents a voluntary information collection burden to the industry. Realistic analyses are not required of licensees not electing this option.
10 CFR 50.46(a)(3)(i)- requires that each applicant for, or holder of, an operating license or construction permit, other than a holder of a license for a reactor facility for which the certifications required under 10 CFR 50.82(a)(1) have been submitted, shall estimate the effect of any change to, or error in, an acceptable evaluation model, or in the application of such a model, to determine if the change or error is significant. For this purpose, a significant change or error is one which results in a calculated peak fuel cladding temperature differing by more than 500F from the temperature calculated for the limiting transient using the last acceptable model, or is a cumulation of changes and errors, such that the sum of the absolute magnitudes of the respective temperature changes is greater than 500F.
10 CFR 50.46(a)(3)(ii)- requires that, for each change to, or error discovered in, an acceptable evaluation model or in the application of such a model that affects the temperature calculation, the applicant or licensee shall report the nature of the change or error, and its estimated effect on the limiting ECCS analysis, to the Commission at least annually. If the change or error is significant, the applicant or licensee shall provide this report within 30 days and include with the report a proposed schedule for providing a re-analysis or taking other action as may be needed to show compliance with 10 CFR 50.46 requirements. This schedule may be developed using an integrated scheduling system previously approved for the facility by the NRC. For those facilities not using an NRC-approved integrated scheduling system, a schedule will be established by the NRC staff within 60 days of receipt of the proposed schedule. Any change or error correction that results in a calculated ECCS performance that does not conform to the criteria set forth in 10 CFR 50.46(b) is a reportable event as described in 10 CFR 50.55(e), 10 CFR 50.72 and 10 CFR 50.73. The affected applicant or licensee shall propose immediate steps to demonstrate compliance or bring plant design or operation into compliance with 10 CFR 50.46 requirements.
The effort associated with the reports required by 10 CFR 50.46 will vary, depending upon the nature of the ECCS model change or error being addressed. Most of the annual reports disclose that no changes were made to the ECCS evaluation or convey information about minor changes. These reports will require little effort to prepare. Other annual reports may be based on extensive re-analysis of ECCS performance, resulting in a greater expenditure of effort. To arrive at its estimate of the burden associated with the annual reports, the staff used its understanding of the types of reports typically submitted and its experience in the level of effort required to conduct ECCS evaluations.
10 CFR 50, Appendix K.I.A.- offers licensees the option to use a reduced power level margin for ECCS evaluation or maintain the current margin of 2% power. To use this option and apply a lower assumed power level, licensees would be required to demonstrate
the uncertainties associated with measuring reactor thermal power. The resulting change to ECCS evaluation results must be reported per 10 CFR 50.46(a)(3) and filed as a license amendment.
10 CFR 50, Appendix K.II.1.a.- requires that a description of each evaluation model be furnished. The description shall be sufficiently complete to permit technical review of the analytical approach including the equations used, their approximations in difference form, the assumptions made, and the values of all parameters or the procedure for their selection, as for example, in accordance with a specified physical law or empirical correlation.
10 CFR 50, Appendix K.II.1.- requires that a complete listing of each computer program be furnished to the NRC upon request in the same form as used in the evaluation model (EM).
NRC does not anticipate the need to request such information during this clearance period.
SECTION VIII- 50.47, 50.54(q & t), Appendix E, Emergency Planning Section 50.47 contains emergency planning standards that must be met in onsite and offsite emergency plans for a nuclear power reactor. Appendix E to 10 CFR Part 50 specifies the content of emergency plans for production and utilization facilities and establishes the minimum requirements for emergency plans to provide reasonable assurance that public health and safety is not endangered by operation of the facility concerned.
Section 50.54 establishes license conditions for licenses issued by the NRC.
Section 50.54(q) requires nuclear power, research reactor and/or fuel facility licensees to follow and maintain in effect emergency plans which meet the applicable standards in 10 CFR 50.47 and requirements in Appendix E to 10 CFR Part 50. Section 50.54(q) authorizes licensees to make changes to their emergency plans without NRC approval provided the licensee performs and retains an analysis demonstrating that the change(s) does/do not reduce the effectiveness of the plan and establishes the record keeping and reporting requirements for changes made to an emergency plan. Changes made to emergency plans must be submitted to the NRC within 30 days after the change is put into effect to allow the NRC to review the changes in a timely manner. Without a timely review, changes to personnel, procedures, equipment, or facilities that could adversely affect emergency preparedness, including failure to maintain an effective emergency plan, could exist without being examined by the NRC. The NRC could be unaware of potential reductions in the adequacy of emergency preparedness for an extended period of time, such that the revised plans may no longer provide reasonable assurance that adequate protective measures can and will be taken in the event of a radiological emergency.
Section 50.54(t) requires licensees to provide for the development, revision, implementation, and maintenance of its emergency preparedness program, and specifies that all program elements must be periodically reviewed by persons who have no direct responsibility for the implementation of the program.
Inspection Reporting Requirements for Emergency Preparedness Inspections are an important element of NRCs reactor oversight process (ROP), in that they ensure that licensees continue to meet applicable regulatory requirements. The NRC
evaluates plant performance by analyzing two distinct inputs: (1) inspection findings resulting from NRCs inspection program, and (2) performance indicators (PIs) reported by the licensee. There are three emergency preparedness PIs: (1) drill and exercise performance, (2) emergency response organization drill and exercise participation, and (3) alert and notification system reliability. The data which make up the PIs are generated by the licensees, and reported to the NRC on a quarterly basis.
10 CFR 50.4(b)(5)- (Emergency plan and related submittals) 10 CFR 50.4(b)(5) provides the specific regulatory requirements for the submittal of written communications associated with emergency plans submitted under 10 CFR 50.34, changes to an emergency plan maintained under 10 CFR 50.54(q), and emergency implementing procedures as described in Section V, Implementing Procedures, of Appendix E to 10 CFR Part 50.
SECTION IX- 50.48, Appendix R, Fire Protection 10 CFR 50.48(a)- requires that each operating nuclear power plant have a fire protection plan that satisfies Criterion 3 of 10 CFR 50 Appendix A. This fire protection plan must describe the overall fire protection program for the facility, identify the various positions within the licensee's organization that are responsible for the program, state the authorities that are delegated to each of these positions to implement those responsibilities, and outline the plans for fire protection, fire detection and suppression capability, and limitation of fire damage. The plan must also describe specific features necessary to implement the program described above, such as administrative controls and personnel requirements for fire prevention and manual fire suppression activities, automatic and manually operated fire detection and suppression systems, and the means to limit damage to structures, systems, and components important to safety so that the capability to safely shut down the plant is ensured. Licensees shall retain the fire protection plan and each change to the plan as a record until the Commission terminates the reactor license and shall retain each superseded revision of the procedures for three years from the date it was superseded.
10 CFR 50.48(b)- requires that plants licensed to operate before January 1, 1979, meet sections III.G, III.J, and III.O of 10 CFR Part 50, Appendix R; and fire protection features accepted by the staff in fire protection safety evaluation reports.
10 CFR 50.48(c)- was implemented in 2004 to provide licensees with the option to transition their fire protection programs to ones based on National Fire Protection Association Standard NFPA 805, Performance-Based Standard for Fire Protection for Light Water Electric Generating Plants, 2001 Edition [69 FRN 33536, June 16, 2004]. The NRC has received 32 Letters of Intent covering 47 units. Forty-six units have already completed the transition. The remaining unit will not be transitioning.
10 CFR 50.48(f)- requires licensees that have submitted 10 CFR 50.82(a)(1) certifications to maintain a fire protection program to address the potential for fires which could cause the release or spread of radioactive materials. Several units have recently shutdown or announced their intention to shutdown in the near future and then move to the decommissioning process.
10 CFR 50.48(f)(2)- requires that the fire protection program be assessed by the licensee on a regular basis and revised, as appropriate, during decommissioning.
10 CFR 50.48(f)(3)- permits the licensee to make changes to the fire protection program without prior NRC approval if the changes do not reduce the effectiveness of fire protection for facilities, systems, and equipment which could result in a radiological hazard.
10 CFR 50 Appendix R,- "Fire Protection Program for Nuclear Power Facilities Operating Prior to January 1, 1979," includes sections III.G, III.J, and III.O that are required to be met by plants licensed to operate before January 1, 1979.Section III.G requires the capability to safely shut down. III.J requires emergency lighting. III.O requires the reactor coolant pump oil collection systems.
10 CFR 50 Appendix R,- "Fire Protection Program for Nuclear Power Facilities Operating Prior to January 1, 1979," also require each nuclear power plant to have a fire brigade (III.H), documented drills (Section III.I.3.d) and documented training records for each fire brigade member (Section III.I.4). Portions of 10 CFR 50 Appendix R were backfit to nuclear power plant licensees, however Sections III.H and III.I were not. All nuclear power plants have fire brigades, drills and training, but those features are not based on the rule requirements captioned above. Therefore, there is no burden associated with this section of 10 CFR 50, Appendix R.
Forty-six nuclear units have already transitioned to performance-based fire protection programs under 10 CFR 50.48(c). These comply with requirements analogous to those under 10 CFR 50 Appendix R, Section III.G, as part of their new fire protection programs or provide justification using performance-based methods for other means of complying with GDC 3 of Appendix A to 10 CFR 50 (Responses on the part of the NFPA 805 licensees can be assumed to be incorporated into their reporting requirements under Section 50.48(c).)
SECTION X- 50.49, Environmental Qualification:
Recordkeeping Requirements 10 CFR 50.49(a)- requires applicants and licensees of nuclear power plants, other than a nuclear power plant for which 10 CFR 50.82(a)(1) certifications have been submitted, to establish a program for qualifying the electric equipment important to safety as defined in 10 CFR 50.49. The current licensees have completed this requirement. Additional information is expected to be collected from approximately 4 new combined operating license (COL) holders.
10 CFR 50.49(d)- requires applicants and licensees to prepare a list of electric equipment important to safety, and include the performance specifications under conditions existing during and following design basis accidents, the electric characteristics for which performance under specified conditions can be ensured, and the environmental conditions in which it must operate. Applicants and licensees must keep the list and information in the file current. All current licensees have prepared lists of equipment and performance specifications, and future information collection under this section of the regulation is required to the degree it is necessary for keeping the information current. New COL applicants would need to prepare and maintain this list of electrical equipment important to safety that is covered under this section.
10 CFR 50.49(f)- requires each item of electric equipment important to safety to be qualified by one of four specified methods, all with a supporting analysis to show that the equipment to be qualified is acceptable. Licensees have completed this requirement for existing plant equipment. However, this requirement remains active for qualification of new equipment installations and for replacement equipment that falls under the scope of this regulation. The COL applicants would need to qualify each item of electric equipment important to safety under one of four specified methods, and perform a supporting analysis to show that the equipment to be qualified is acceptable. All COL applicants are expected to qualify electrical equipment during the clearance period.
10 CFR 50.49(j)- requires that a record of the qualification, including documentation required by 10 CFR 50.49(d), be maintained in an auditable form for the entire period during which the covered item is installed or stored for future use in the nuclear power plant. This is required to permit verification that each item of electric equipment important to safety is qualified for its application and meets its specified performance requirements when it is subjected to the conditions predicted to be present when it must perform its safety function, up to the end of its qualified life. This requirement would not apply to COLs because the plants would be in the initial design phase.
10 CFR 50.49(l)- requires replacement equipment to be qualified in accordance with the provisions of 10 CFR 50.49 unless there are sound reasons to the contrary. Therefore, unless there is suitable justification for some alternate course of action, new equipment installations and replacement equipment that fall under the scope of 10 CFR 50.49 must be qualified in accordance with 10 CFR 50.49 requirements, including the documentation requirements of 10 CFR 50.49(d), CFR 50.49(f) and CFR 50.49(j). The licensee must maintain any justification for an alternative course of action on site, and the justification must be available for inspection as part of the inspection procedure. This requirement would not apply to COLs because the plants would be in the initial design phase.
Reporting Requirements 10 CFR 50.49(h)- requires each licensee to notify the NRC of any significant equipment qualification problem that may require extension of the completion date, provided pursuant to 10 CFR 50.49(g), within 60 days of its discovery. Since this requirement has been completed by all licensees, no further collection of information is required under this section of the regulation. This requirement would not apply to COLs because the activity would be completed as part of the initial design.
10 CFR 50.49(i)- requires applicants for operating licenses granted after February 22, 1983, but prior to November 30, 1985, to perform an analysis to ensure that the plant can be safely operated pending completion of equipment qualification required by this section.
This requirement is complete and is not applicable to new COLs.
SECTION XXX- 50.120, Training & Qualification of Nuclear Power Point Personnel Section 306 of the Nuclear Waste Policy Act of 1982, Public Law 97-425, directed the NRC to promulgate regulations or other appropriate Commission regulatory guidance for the training and qualifications of civilian nuclear power plant operators, supervisors, technicians and other appropriate operating personnel. In April 1993, the NRC published 10 CFR 50.120.
10 CFR 50.120- requires that each applicant for, and holder of, an operating license for a nuclear power plant establish, implement, and maintain training programs for 9 categories of power plant personnel that provide qualified personnel to operate and maintain the facility in a safe manner in all modes of operation.
10 CFR 50.120(b)(1)- requires that applicants and licensees develop and maintain these training programs with a systems approach to training (SAT) based on job performance requirements. Section 10 CFR 50.120 builds on existing industry practice related to training. Training for the personnel covered by 10 CFR 50.120 has already been developed and implemented by the industry.
10 CFR 50.120(b)(2)- requires power plant applicants and licensees to periodically evaluate and revise the training programs to reflect industry experience, changes to the site, procedures, regulations, and quality assurance requirements.
10 CFR 50.120(b)(2)- also requires periodic review of the training programs by licensee management, and requires licensees and applicants to maintain and keep available for NRC inspection, materials sufficient to verify the adequacy of the training programs.
Documents related to the establishment, implementation, and maintenance of the training programs must be kept. Documentation demonstrating the job performance qualifications of personnel performing in positions covered by 10 CFR 50.120, including contractor personnel, must be maintained for each employee for the duration of employment.
SECTION XXXI - Appendix J, Containment Leakage The 10 CFR 50 Appendix J is divided into two options: Option A, Prescriptive Requirements, and Option B, Performance-Based Requirements. Option B is a performance-based rule in which the intervals between tests are established, in part, based on the previous leakage rate performance of the component or system. A licensee may adopt, on a voluntary basis, either or both of the overall leakage testing requirements (Type A tests) and the local leakage rate testing requirements (Type B and C tests) of Option B.
In either case, the recordkeeping requirements of Option B must be implemented. The pre-operational and periodic Type A, B, and C tests must be documented to show that the performance criteria for leakage have been met. The comparison to previous results of the performance of the overall containment system, and of individual components within it, must be documented to show that the test intervals established for the containment system and components within it are adequate. These records must be available for inspection at plant sites, but licensees are not required to submit these results to the Nuclear Regulatory Commission (NRC).
Neither option of 10 CFR 50 Appendix J contains specific reporting requirements. All requirements to make reports to the NRC were eliminated from 10 CFR 50 Appendix J (in what is now known as Option A) in 1995, and Option B, promulgated in 1995, also contains no reporting requirements, other than referring to the requirements contained in 10 CFR 50.72 and 10 CFR 50.73. For either option, licensees, under 10 CFR 50.72 and 10 CFR 50.73, currently report any instances of leakage exceeding authorized limits in the Technical Specifications (TS) of the license.
Although there are no specific reporting requirements, each option has recordkeeping requirements.
OPTION A 10 CFR 50, Appendix J, Section III requires licensees to develop a program consisting of a schedule for conducting Type A, B and C tests for leak testing the primary reactor containment and related systems and components penetrating the primary containment pressure boundary. Since this information is presented in the Final Safety Analysis Report (FSAR), any burden involved in its preparation is considered under preparation of the FSAR.
10 CFR 50, Appendix J, Section III.A.6 states that if a licensee's containment does not pass the Type A test, the test schedule applicable to subsequent Type A tests will be reviewed and approved by the Commission. No Commission notifications are expected during this clearance period.
10 CFR 50, Appendix J, Section V.B requires recordkeeping of test results. The pre-operational and periodic tests must be documented in a readily available summary report that will be made available for inspection, upon request, at the nuclear power plant. The summary report shall include a schematic arrangement of the leakage rate measurement system, the instrumentation used, the supplemental test method, and the test program selected as applicable to the pre-operational test, and all the subsequent periodic tests.
The report shall contain an analysis and interpretation of the leakage rate test data for the Type A test results to the extent necessary to demonstrate the acceptability of the containment's leakage rate in meeting acceptance criteria.
10 CFR 50, Appendix J.Section V.B. 2 For each periodic test, leakage test results from Type A, B, and C tests shall be included in the summary report. The summary report shall contain an analysis and interpretation of the Type A test results and a summary analysis of periodic Type B and Type C tests that were performed since the last Type A test. Leakage test results from Type A, B, and C tests that failed to meet the acceptance criteria of Appendix J, Sections III.A.5(b), III.B.3, and III.C.3 shall be included in a separate accompanying summary report that includes an analysis and interpretation of the test data, the least squares fit analysis of the test data, the instrumentation error analysis, and the structural conditions of the containment or components, if any, which contributed to the failure in meeting the acceptance criteria.
Results and analyses of the supplemental verification test employed to demonstrate the validity of the leakage rate test measurements shall also be included.
OPTION B 10 CFR 50, Appendix J, Section III.A requires that a Type A test be conducted 1) after the containment system has been completed and is ready for operation and 2) at a periodic interval based on the historical performance of the overall containment system as a barrier to fission product releases to reduce the risk from reactor accidents. The test results must be compared with previous results to examine the performance history of the overall containment system to limit leakage.
10 CFR 50, Appendix J, Section III.B requires Type B and Type C pneumatic tests to be conducted (1) prior to initial criticality, and (2) periodically thereafter at intervals based on the safety significance and historical performance of each boundary and isolation valve to
ensure the integrity of the overall containment system as a barrier to fission product release to reduce the risk from reactor accidents.
The performance-based testing program must be established which contains a performance criterion for Type B and C tests, consideration of leakage-rate limits and factors that affect performance, evaluations of performance, and comparison to previous test results.
10 CFR 50, Appendix J, Section IV requires that the results of pre-operational and periodic Type A, B, and C tests must be documented to show that performance criteria for leakage have been met. The comparison to previous results of the performance of the overall containment system and of individual components within it must be documented to show that the test intervals established for the containment system and components within it are adequate. These records must be available for inspection at plant sites.
10 CFR 50, Appendix J, Section V.A requires that if the requirements for tests in Option B,Section III.A, or Option B,Section III.B, are implemented, the recordkeeping requirements in Option B, IV, for these tests must be substituted for the reporting requirements of the tests contained in Option A.
10 CFR 50, Appendix J, Section V. B. 2 requires that a licensee or applicant for an operating license may adopt Option B, or parts thereof, by submitting its implementation plan and request for revision to technical specifications. (Burden for changes to TS is covered by the Section 2 Supporting Statement.)
10 CFR 50, Appendix J.Section V. B. 3 The regulatory guide or other implementation document used to develop a performance-based leakage program must be included, by general reference, in the plant's TS. The submittal for TS revisions must contain justification, including supporting analyses, if the licensee chooses to deviate from methods approved by the Commission and endorsed in a regulatory guide.
10 CFR 50. Appendix J.Section V. B. 4 The detailed licensee programs for conducting testing under Option B must be available at the plant site for inspection.
SECTION XXXIII- Appendix S, Earthquake Engineering Criteria 10 CFR 50 Appendix S IV(a)(3) states that if vibratory ground motion exceeds that of the Operating Basis Earthquake Ground Motion, or if significant plant damage occurs, the licensee must shut down the nuclear power plant. If systems, structures, or components necessary for the safe shutdown of the nuclear power plant are not available after the occurrence of the Operating Basis Earthquake Ground Motion, the licensee must consult with the Commission and must propose a plan for the timely, safe shutdown of the nuclear power plant. Both 10 CFR 50 Appendix S IV(a)(3) and 10 CFR 50.54(ff) require that prior to resuming operations, the licensee must demonstrate to the Commission that no functional damage has occurred to those features necessary for continued operation without undue risk to the health and safety of the public and that the licensing basis is maintained.
