Docket ID NRC-2021- 0173 Draft regulatory issue summary (RIS) Operational Leakage

References:

(1) 87 FR 2361, 10 CFR Chapter I [NRC-2021- 0173] Operational Leakage; (2) ASME BPVC Section XI, American Society of Mechanical Engineers (ASME) Boiler and Pressure Vessel Code (BPVC) Code,Section XI, Rules for Inservice Inspection of Nuclear Power Plant Components.

PSEG Nuclear, LLC (PSEG) offers comments on Reference (1) and respectfully requests that the Nuclear Regulatory Commission (NRC) withdraw the proposal. PSEG endorses comments the Nuclear Energy Institute (NEI) is concurrently submitting on this matter.

In Reference (1), the NRC defines operational leakage and through wall. NRC asserts that 10 CFR 50.55a(g) requires only those methods described in the provisions of the applicable in -service inspection requirements to demonstrate operability of through-wall operational leakage from ASME BPVC Class 1, 2, or 3 structures, systems and components ( SSCs). Moreover, the NRC states operational leakage must be Office of Administration Page 2 LR-N22-0027

addressed in the same manner as leakage detected during an ASME BPVC,Section XI, pressure test.

PSEG agrees that the presence of operational leakage requires evaluation of technical specification operability. Technical specifications for the Hope Creek and Salem Generating Stations prohibit any pressure boundary leakage from the reactor coolant system (ASME BPVC Class 1). However, with respect to ASME BPVC Class 2 or 3 SSCs, PSEG cannot find regulatory requirement s limiting operability determinations to only those methods authorized for leakage detected during an ASME BPVC,Section XI, pressure test. It is contradictory to first distinguish operational leakage from pressure test leakage and then to require application of the same evaluation methods to both types of leakage.

Reference (2) prescribes approved methods to evaluate or repair leaks discovered during ISI examination. However, leaks discovered during operation are, as the NRC points out, distinct from pressure test leakage subject to Reference (2) requirements.

The nuclear power industry has established methods to evaluate oper ability when degraded conditions are present. These methods demonstrate whether a SSC can perform specified safety functions - that is whether a SSC required to be operable by plant technical specifications is operable.

The draft RIS is inconsistent with NRC values embodied in the Principles of Good Regulation. For example, imposing ASME BPVC,Section XI methods to operability determinations is not commensurate with the perceived risk reduction. W e disagree with the draft RISs contention on how operability must be assessed. Contrary to the language used in the draft RIS, there are no regulatory requirements in Section XI of the ASME BPV Code, 10 CFR 50.55a, or the Technical Specifications (TS) that require use of Section XI flaw acceptance and evaluation methods to evaluate the structural integrity of Class 2 and 3 SSCs to determine operability in response to operational leakage. The established operability decision-making process is a proven and effective process that can safely allow productive nuclear generating stations to continue operating if existing ASME/NRC approved evaluation methods mandated by the RIS are impractical to apply.

Further, the proposed RIS imposes heightened regulatory requirements without the openness provided by form al rulemaking that the agency previously considered both appropriate and necessary for this new requirement. NRC subsequently withdrew the proposed rule change while unilaterally asserting there is no change in NRC position or Office of Administration Page 3 LR-N22-0027

interpretation. See, 86 FR 16087. This proposed RIS circumvents the formal rulemaking process the agency initially considered both necessary and appropriate for this new requirement. Additionally, it would also constitute unanalyzed back -fitting, contrary to the requirements of 10 CFR 50.109.

In closing, PSEG reiterates its endorsement of NEI comments on the RIS proposed by Reference (1). Thank you for your attention to this matter.

There are no regulatory commitments contained in this letter.
