DESCRIPTION AND JUSTIFICATION OF PROPOSED OQAP CHANGE QA-093

1.0

SUMMARY

DESCRIPTION STP Nuclear Operating Company (STPNOC) is submitting a revision to the South Texas Project Electric Generating Station (STPEGS) Operations Quality Assurance Plan (OQAP) in accordance with 10 CFR 50.54(a)(4). The proposed changes are considered a reduction in commitment which require approval by the Nuclear Regulatory Commission (NRC) prior to implementation. Specifically, STPNOC is proposing to revise the OQAP to decommit from NQA-1-1983 only

2.0 DESCRIPTION

OF THE CHANGE The proposed changes to the STPNOC OQAP will do the following:

Add specific definitions from NEI 16-07, Improving the Effectiveness of Issue

Definitions Chapter of the OQAP

Add statements to OQAP Chapter 2.0, Table 1, Program Commitments, regarding the exception STPNOC is taking to the NQA-1-1983 definition for CAQ, which includes a definition for SCAQ and a statement that STPNOC will ensure Targeted Program Controls are applied to certain non-safety related systems, structures, or components (SSCs)

Because this proposed change does not meet any of the criteria provided in 10 CFR 50.54(a)(3)(i) through (vi), STPNOC considers it a reduction in commitment and shall be processed in accordance with 10 CFR 50.54(a)(4).

Attachment 2 of this Enclosure provides the marked-up pages of the OQAP with the proposed changes and Attachment 3 provides the retyped pages. It should be noted that STPNOC is not requesting NRC endorsement of NEI 16-07 by submitting this proposed OQAP change.

3.0 JUSTIFICATION FOR THE PROPOSED CHANGE The proposed change to the definitions of CAQ and SCAQ align with the implementation of the industry-developed definitions in NEI 16-07. The CAQ definition from NQA-1-1983, committed to by STPNOC, encompasses failures, malfunctions, deficiencies, defective items. The scope of this definition, and the definition of SCAQ, which is included in the CAQ definition, has resulted in the undesirable and distracting accumulation of process controls and administrative requirements over the years. This accumulation affects the effectiveness of plant supervisors and managers by:

Creating administrative distractions not focused on conditions affecting the safety-related functions of SSCs.

Creating an over-reliance on the Corrective Action Program (CAP) to address issues.

NOC-AE-24004034 Enclosure Page 2 of 4

Duplicate use of CAP as a tool for departmental work tracking or management of lower-level issues.

Establishing additional reviews or committees to address issues of relatively low significance.

The proposed change continues to allow for condition reports to serve as the primary tool for raising and documenting issues; however, the issues that do not affect the safety-related function of an SSC will not be categorized as a CAQ.

This will allow station leaders and workers to have a greater focus on conditions adverse to quality and improve the prioritization of resources when addressing conditions adverse to quality.

4.0 BASIS FOR CONCLUDING THAT THE REVISED PROGRAM CONTINUES TO SATISFY THE CRITERIA OF 10 CFR 50 APPENDIX B AND THE PREVIOUSLY ACCEPTED QUALITY ASSURANCE PROGRAM COMMITMENTS

within NQA-1 (1983), except for the CAQ and SCAQ definitions. Multiple utilities have incorporated the CAQ and SCAQ definitions from NEI 16-07 into their fleet or site quality assurance plans.

The quality assurance requirements presented in 10 CFR 50, Appendix B, apply to the design, manufacture, construction, and operation of SSCs preventing or mitigating the consequences of postulated accidents that could cause undue risk to the health and safety of the public. Such structures, systems, and

provide adequate confidence that a safety-related structure, system, or component will perform satisfactorily in service. The associated requirements apply to all activities affecting the safety-related functions of SSCs, including designing, purchasing, fabricating, handling, shipping, storing, cleaning, erecting, installing, inspecting, testing, operating, maintaining, repairing, refueling, and modifying.

While the regulation does not strictly define what a CAQ is, the introduction of this part of the regulation describes the impact on the function of a safety-related system in consideration of how to determine if a CAQ exists.

NOC-AE-24004034 Enclosure Page 3 of 4

the implementation of dry cask storage, STPNOC will remain in compliance with 10 CFR 72.172, Corrective Action, with implementation of the proposed change.

STPNOC has implemented the Important to Safety (ITS) categories A, B, and C

Approach to Developing Quality Assurance Programs for Packaging Radioactive

purposes of identifying CAQs and SCAQs. This interpretation is based on the guidance in Regulatory Guide 7.10, Appendix A, where consequences of a failure or malfunction could directly or indirectly result in a condition that would adversely affect public health and safety.

Implementation of this proposed change to the CAQ and SCAQ definitions will

and Graded Quality Assurance Programs to the extent that the NRC has granted STP an exemption from the regulations as described in the Safety Evaluation on Exemption Requests from Special Treatment Requirements of 10 CFR Parts 21, 50, and 100 (TAC NOS. MA6057 AND MA6058). This includes Full Program Controls that are the highest levels of controls and oversight applied to safety-related SSCs categorized as High Safety Significant (HSS), and Targeted Program Controls that are selected program controls applied to certain non-safety-related SSCs categorized as either HSS or Medium Safety Significant (MSS) as prescribed in the STPEGS OQAP.

The proposed change for the CAQ and SCAQ definitions will continue to allow for condition reports to serve as the primary tool for raising and documenting issues; however, the issues that do not affect the safety-related function of an SSC will not be categorized as a CAQ. This will allow station leaders and workers to have a greater focus on conditions adverse to quality and improve the prioritization of resources when addressing conditions adverse to quality.

This improvement opportunity does not change the current expectations involving issue identification; therefore, employees will continue to be encouraged and expected to maintain a low threshold for condition reporting.

Supervisors, managers, and executives will ensure that a workplace environment supportive of problem identification, consistent with a healthy nuclear safety culture is maintained.

5.0 PRECEDENT No precedent NOC-AE-24004034 Enclosure Page 4 of 4

6.0 CONCLUSION

The proposed change continues to satisfy the criteria of 10 CFR 50, Appendix B, as incorporated into the OQAP.
