REACTOR SAFETY
IntroductionThe NRC conducted an inspection to verify that licensee personnel adequatelypreserved the facility safety system design and performance capability and that licenseepersonnel preserved the initial design in subsequent modifications of the systemsselected for review. The scope of the review also included any necessary nonsafety-related structures, systems, and components that provided functions to support safetyfunctions. This inspection also reviewed the licensee's programs and methods for monitoring the capability of the selected systems to perform the current design basisfunctions. This inspection verified aspects of the initiating events, mitigating systems,and barrier cornerstones.Licensee personnel based the probabilistic risk assessment model for the South TexasProject on the capability of the as-built safety systems to perform their intended safetyfunctions successfully. The team determined the area and scope of the inspection by reviewing the licensee's probabilistic risk analysis models to identify the most risksignificant systems, structures, and components. The team established this accordingto their ranking and potential contribution to dominant accident sequences and/orinitiators. The team also used a deterministic approach in the selection process by considering recent inspection history, recent problem area history, and all modifications developed and implemented. The team assessed the adequacy of calculations, analyses, engineering processes, andengineering and operating practices that licensee personnel used for the selected safety system and the necessary support systems during normal, abnormal, and accidentconditions. Acceptance criteria used by the team included NRC regulations, thetechnical specifications, applicable sections of the Updated Final Safety Analysis Report, applicable industry codes and standards, and industry initiatives implemented by the licensee's programs.
1R02 Evaluations of Changes, Tests, or Experiments
a. Inspection Scope
The team inspected the effectiveness of the licensee's implementation of changes tofacility structures, systems, and components, risk-significant normal and emergencyoperating procedures; test programs; and the updated final safety analysis reports in accordance with 10 CFR 50.59, "Changes, Tests, and Experiments." The team utilizedInspection Procedure 71111.02 for this inspection.The minimum sample size for this procedure is 6 evaluations and 12 screenings. Theteam reviewed 9 licensee-performed 10 CFR 50.59 evaluations to verify that licensee personnel had appropriately considered the conditions under which the licensee may make changes to the facility or procedures or conduct tests or experiments without prior NRC approval. The team reviewed 13 licensee-performed 10 CFR 50.59 screenings, in
-2-which the licensee personnel determined that evaluations were not required, to ensurethat the exclusion of a full evaluation was consistent with the requirements of10 CFR 50.59. The team selected evaluations and screenings in the cornerstones of initiating events, mitigating systems, and barrier integrity, with the majority of evaluationsand screenings encompassing the mitigating systems cornerstone. The team selectively reviewed the licensee's design modifications and supportingdocuments associated with replacement of underground cables serving the 480 Vac loads in the essential cooling water (ECW) intake structure, replacement of Class 1E 480 Vac motor control center buckets, and Class 1E 120 Vac inverters. The review focused on the potential impact of the changes on the design and licensing basis, and post-modification testing of the cable and inverters. The specific documents the team inspected are identified in the list of documents reviewed. The team also reviewed and evaluated the most recent licensee 10 CFR 50.59 programself assessment to determine whether licensee personnel conducted sufficient in-depth analyses of their program to allow for the identification and subsequent resolution of problems or deficiencies. In addition, the team reviewed the licensee's self assessment plan to verify the licensee's program in resolving issues associated with the application of the 50.59 process.
b. Findings
No findings of significance were identified.
1R21 Safety System Design and Performance Capability (71111.21)The minimum sample size for this procedure is one risk-significant system for mitigatingan accident or maintaining barrier integrity.
The team completed the required sample size by reviewing the ECW and the emergency electrical systems. The primary reviewprompted parallel review and examination of support systems, such as, power,instrumentation and controls, cooling and related structures and components..1System Requirements
a. Inspection Scope
The team inspected the following attributes of the selected systems:
- (1) processmedium (water, steam, air, electrical signal),
- (2) energy sources,
- (3) control systems,and
- (4) equipment protection. The team examined the procedural instructions to verify that instructions were consistent with actions required to meet, prevent, and/or mitigate design basis accidents. The team also considered requirements and commitments identified in the Updated Final Safety Analysis Report, technical specifications, design basis documents, and plant drawings. In conjunction with the primary review, a parallel review and examination of support systems and related structures and componentswere also conducted.

No findings of significance were identified..2System Condition and Capability
a. Inspection Scope
The team reviewed the periodic testing procedures for the selected systems to verifythat the capabilities of the systems were periodically verified. The team also reviewedsystem health reports, as well as a sample of the governing procedures anddocumentation for the control of calculations that were translated into values used inplant procedures. In addition, the team performed walkdowns of the selected systemsto ascertain the material condition of the systems.To assess the licensee's monitoring of the condition of underground cables, the teamreviewed a sample of insulation resistance test procedures, test results, and trending for the power cable serving the 4160 Vac ECW pump motors and the power cable serving the 480 Vac motor control centers in the ECW intake structure. The team also reviewed a sample of surveillances of the 13.8/4.16 kV engineered safety features transformers.
The specific documents the team inspected are identified in the list of documentsreviewed.The team also reviewed the operation of the systems by reviewing normal, abnormal,and emergency operating procedures. The review included the Updated Final Safety Analysis Reports, technical specifications, design calculations and drawings.
b. Findings
No findings of significance were identified..3Identification and Resolution of Problems
a. Inspection Scope
The team reviewed a sample of problems associated with the selected systems thatwere identified by licensee personnel in the corrective action program to evaluate the effectiveness of corrective actions related to design issues and aging hardware.
The sample included open and closed condition reports and their disposition via maintenance work orders, or apparent cause evaluations, as documented in the licensee's corrective action program. The sample covered the past 3 years and the documents reviewed are listed in the attachment to this report. Inspection Procedure 71152, "Identification and Resolution of Problems," was used as guidance to perform this part of the inspection. The team reviewed a sample of licensee condition reports involving electricalcomponents and cable. The sample included conditions whereby cables in the underground duct bank to the ECW intake structure had become flooded, or had potential for flooding, and where the licensee had reported adverse trends of insulation
-4-resistance for underground cable serving 480 Vac ECW loads. The specific conditionreports the team inspected are identified in the list of documents reviewed.
