.1 ADMINISTRATIVE PROCEDURES
.1.1 Conformance with Regulatory Guide 1.33 ulatory Guide 1.33, issued February 1978, Quality Assurance Program Requirements, is used uidance for the preparation of administrative and station procedures.
.1.2 Preparation of Procedures paration, review and approval of procedures is as described in the Quality Assurance Program cription (QAPD) Topical Report.
.1.3 Procedures ministrative control and station procedures cover a wide range of topics. Major areas are cribed as follows.
nding Orders to Operating Personnel ministrative control procedures define the authorities and responsibilities of operating onnel. The procedures specify the number of personnel with reactor operator and senior tor operator licenses required to be on site or at the controls in all plant conditions. The inistrative procedures direct the proper maintenance, review, and disposition of operating rds, establish requirements for shift turnover, and establish the authority and responsibilities he person in charge of the control room to limit access. Procedures also direct the assignment hift personnel to duty stations, establish limits for scheduled working hours, provide methods imely and concise feedback of operating experience to applicable plant staff, and describe hods used to verify operational activities are performed correctly. Plant procedures also vide for shift turnover such that all necessary information is properly transmitted to the oming shifts.
cial Orders of a Transient or Self-Cancelling Character ht orders are issued as necessary to provide guidance to operating shifts and are of a porary nature but will be incorporated into an administrative control if the need becomes manent.
ructions are written to specify proper methods of obtaining clearances on plant equipment for ntenance or construction and to specify procedures for control of jumpers, inhibits, and wire oval. The clearance procedure assigns responsibility for clearance issue to the shift supervisor.
censed operator, after ensuring he is aware of the effect of the activity on the system, is uired to authorize all maintenance, tests, and surveillances performed on plant systems. Upon pletion of the item, the document is returned to the operator for acceptance or for the purpose eturning the system to service. The administrative procedures which control these evolutions vide the required explicit notification of operational personnel whenever a safety related em is removed from and returned to service. The clearance procedure also contains certain rictions on the issuance of a clearance. The instructions for control of jumpers, inhibits, and e removal allow temporary alterations to critical structures, systems, or components to litate tests, maintenance, or operations. They specify administrative procedures to be followed erforming such alterations.
trol of Maintenance and Modifications ministrative control procedures implement the review and approval requirements for ntenance and modifications. These procedures include the control of plant modifications and ntenance on safety-related equipment. These procedures establish a framework of special cess and maintenance procedures.

10.1 INTRODUCTION
lstone has implemented 10 CFR 50.69 using the processes for categorization of Risk-rmed Safety Class (RISC)-1, RISC-3, and RISC-4 structures, systems, and components Cs) using:
Probabilistic Risk Assessment (PRA) model to evaluate risk associated with internal events, including internal flooding; the Appendix R program to evaluate fire risk; and the shutdown safety assessment process to assess shutdown risk; The Arkansas Nuclear One, Unit 2 (AN0-2) passive categorization method to assess passive component risk for Class 2 and Class 3 SSCs and their associated supports; The results of non-PRA evaluations that are based on the IPEEE [Individual Plant Examination of External Events] Screening Assessment for External Hazards, i.e., seismic margin analysis (SMA) to evaluate seismic risk, and a screening of other external hazards updated using the external hazard screening significance process identified in ASME/
0.2 SSC CATEGORIZATION outlined in the Safety Evaluation Report (SER) for License Amendment 337 to Renewed ility Operating License No. DPR-65 (Reference 12.10-3), Millstone 2 will use the hodology described in Section 12.10.
hould be noted that 10 CFR 50.69 does not replace the existing safety-related and nsafety-related classification. Instead 10 CFR 50.69 divides these classifications into two categories based on high or low safety significance, such that there are four categories of risk-rmed safety class (RISC), as shown below:
C-1: safety-related SSCs that perform (high) safety significant functions.
C-2: nonsafety-related SSCs that perform (high) safety significant functions.
C-3: safety-related SSCs that perform low safety-significant functions.
C-4: nonsafety-related SSCs that perform low safety-significant functions CRF 50.69(f)(2) requires updating the UFSAR to reflect which systems have been gorized. The list below is revised as part of the periodic UFSAR update to reflect systems that e been categorized.
tem Name iation Monitoring (2404)
0.3.1 Treatment of Component Categories programs or processes that implement the special treatment requirements are revised to gnize that the special treatments no longer apply to RISC-3 and RISC-4 SSCs. The programs rocesses either allow continued application of the special treatments or acceptable alternative tments, as applicable, to provide reasonable confidence that these SSCs would perform their ty-related function under design basis conditions.
those components that are categorized as Low Safety Significant, 10 CFR_50.69(b)(1) allows pliance with alternative requirements in lieu of the following special treatment requirements:
- 2. The portion of the 10 CFR 50.46a(b) that imposes requirements to conform to Appendix B to 10 CFR Part 50
- 3. 10 CFR 50.49
- 5. The in-service testing requirements in 10 CFR 50.55a(f): the in-service inspection and repair, and replacement (with the exception of fracture toughness),
requirements for ASME Class 2 and Class 3 SSCs in 10 CFR 50.55a(g); and the electrical component quality and qualification requirements in Section 4.3 and 4.4 of IEEE 279 and Sections 5.3 and 5.4 of IEEE 603-1991, as incorporated by reference in 10 CFR 50.55a(h)
- 6. 10 CFR 50.65, except for paragraph (a)(4)
- 7. 10 CFR 50.72
- 8. 10 CFR 50.73
- 9. Appendix B to 10 CFR Part 50
- 10. The Type B and Type C leakage testing requirements in both Options A and B of Appendix J to 10 CFR Part 50, for penetrations and valves meeting the following criteria:
- a. Containment penetrations that are either 1-in. nominal size or less, or continuously pressurized.
- b. Containment isolation valves that meet one or more of the following criteria:
- 2. The valve is normally closed and in a physically closed, water-filled system;
- 3. The valves is in a physically closed system whose piping pressure rating exceeds the containment design pressure rating and is not connected to the reactor coolant pressure boundary; or
- 4. The valve is 1-in. nominal size or less.
- 11. Appendix A to Part 100, Sections VI(a)(1) and VI(a)(2), to the extent that these regulations require qualification testing and specific engineering methods to demonstrate that SSCs are designed to withstand the Safe Shutdown Earthquake and Operating Basis Earthquake.
en applying alternative treatment, 10 CFR 59.69 requires that the licensee shall ensure, with onable confidence, that RISC-3 SSCs remain capable of performing their safety-related ctions under design basis conditions, including seismic conditions and environmental ditions and effects throughout their service life.
ormance monitoring is being performed on all RISC-1, RISC-2, RISC-3, and RISC-4 SSCs the station adjusts, as necessary, to either the categorization or treatment process so that the gorization process and results are maintained valid.
0.3.2 Enhanced Treatment of RISC-2 SSCs 10 CFR 50.69 procedures and 10 CFR 50.69(d)(1) require that RISC-2 SSCs perform their ctions consistent with the categorization process assumptions by evaluating treatment being lied to these SSCs to ensure that it supports the key assumptions in the categorization process relate to their assumed performance.
