Proposed Rule entitled: 10 CFR Parts 50 and 52, "Risk-Informed Changes to Loss-of-Coolant Accident Technical Requirements." The Nuclear Regulatory Commission (NRC) proposes to amend its regulations to permit applicants for and/or holders of power reactor operating licenses, standard design certifications, combined licenses, standard design approvals or manufacturing licenses to choose to implement a risk informed alternative to the current requirements for analyzing the performance of emergency core cooling systems (ECCS) during loss of coolant accidents (LOCAs). In addition, the proposed rule would establish procedures and criteria for making changes in plant design and procedures based upon the results of the new analyses of ECCS performance during LOCAs. A licensee or applicant choosing to use the provisions of Section 50.46a would be required to submit a license amendment request with the required information, using the existing processes in Section 50.34 and Section 50.90.
The rule is estimated to result in a net increase of 53,388 hours in the information collection burden. This burden is associated with one-time (48,000 hours) and recurring (5,388 hours) costs to obtain the approval to implement Section 50.46a. The majority of this burden is a one-time burden, which includes fulfilling the requirements of Sections 50.46a(c)(1) (Application), 50.46a(e) (ECCS Evaluations Re-analysis), and 50.46a(f) (Risk-Informed Evaluations). These one-time and annual burdens also have additional associated annual burdens due to recordkeeping requirements.
On behalf of this Federal agency, I certify that the collection of information encompassed by this request complies with 5 CFR 1320.9 and the related provisions of 5 CFR 1320.8(b)(3).
The following is a summary of the topics, regarding the proposed collection of information, that the certification covers:
(i) Why the information is being collected;
(ii) Use of information;
(iii) Burden estimate;
(iv) Nature of response (voluntary, required for a benefit, or mandatory);
(v) Nature and extent of confidentiality; and
(vi) Need to display currently valid OMB control number;
If you are unable to certify compliance with any of these provisions, identify the item by leaving the box unchecked and explain the reason in the Supporting Statement.
