SACADA A Tool for Operator Training and Human Reliability Analysis Y. James Chang, Ph.D.
Human Factors and Reliability Branch Division of Risk Analysis Office of Nuclear Regulatory Research U.S. Nuclear Regulatory Commission Presented at the Regulatory Information Conference Rockville, MD March 12-14, 2019 1

Overview
- A partnership between the U.S. Nuclear Regulatory Commission (NRC) and South Texas Project (STP) developed the SACADA software with two objectives:
- Facilitate operator training
- Provide empirical data to inform human error probability (HEP) estimates
- The NRC is developing SACADA-2
SACADA: Scenario Authoring, Characterization, and Debriefing Application
What Is SACADA?
(Scenario Authoring, Characterization, and Debriefing Application)
- A tool for operator simulator training
- Author simulation scenarios
- Debrief crew performance
- Other uses (e.g., generate reports, automatically e-mail crew performance information)
- A standalone software
- Not connected to the simulator or other plant systems
- A database for human reliability analysis (HRA)
- Provide an empirical data basis to inform the calculations of HEPs 3
Initial Condition Elements (Training Objective Elements)
Malfunctions/Conditions 4
Generic Simulation Scenario Structure Fire in No. 12 Condensate Pump Motor US Enter POP04-ZO-0008, Fire/Explosion CREW Activate the fire alarm, make the announcement, and call out the Fire Brigade SM Review 0ERP01-ZV-IN01 for Emergency Plan Classification (none required)
Scenario Representation in SACADA 5
Different Information Needs between Operator Training and HRA 6
Four students took the same exam with various performance.
100 Piece of cake 80 It was OK.
60 It was somewhat difficult.
20 It was very difficult.
Training Department:
(Retrospective Analysis) Find out why the two students failed the exam and fix the problems.
HRA Analyst:
(Predictive Analysis)
How can I reliably predict the failure probability is 50%?
Two Groups of Human Performance Information 7
Predictive Analysis (Characterization)
Retrospective Analysis (Debriefing)
What are the task challenges?
How well was the task performed?
Tell me more about the performance deficiencies.
How to prevent the deficiencies from reoccurring?

Debriefing Screen Shots Evaluate the Performance 30 Link to INPO Operator Fundamentals
Debriefing Screen Shot Understand the Deficiencies Seven classes Monitoring/Detection Diagnosis/Understanding Procedure Following/Decisionmaking Manipulation Supervision Teamwork Communication Stimulate crew to think Can choose more than one class 32
Reports Exportable formats: PDF, MS Word, and Excel 44
SACADA-1 vs. SACADA-2 STP and Vogtle Electric Generating Plant, Units 3 and 4, Provide Technical Support for SACADA-2 Development SACADA-1 SACADA-2 Collect Simulator Data
Collect Job Performance Measure (JPM) Data
Collect Written Exam Results
Directly Support Crew Notebook
Provide Simulator Guide
Track Crew Performance
(Simulator only)
(All areas)
Track Individual Performance
(All areas) 13 All areas: Simulator, JPM, and written exams.
STP Training Departments User Experience
- More efficient and focused debriefing
- Provides consistency between crews in the debriefs
- Ensures the crew addresses an issue
- Issues cannot be minimizeddrills down to the root cause
- Can be used to track individual crew performance as well as overall department performance
- Addresses ACAD Objective 3.3personnel performance and feedback during training are used to evaluate and modify training programs
- Addresses ACAD Objective 3.2managers are engaged in training activities through monitoring and oversight to provide feedback and direction 14
- Three NRC contractors presented methodologies using SACADA to estimate HEPs in an HRA data workshop and PSAM-14 conference in 2018
- The NRC will present the use of SACADA data for HRA methods during the HRA data workshop on March 14-15, 2019, in 3WFB 3A28, NRC HQs
- You are invited to attend the workshop 15 PSAM: Probabilistic Safety Assessment and Management
Partner with the NRC on SACADA
- Current NRC partnership with U.S. NPPs includes:
- STP: a user since 2012
- Vogtle Units 3 and 4: started to pilot in January 2019
- Partnership principles:
- The NRC provides free software license, training, and technical support
- NPPs share the data with the NRC for HRA improvements
- The NRC welcomes the partnership of the NPPs 16
NRC Is Happy to Partner with the Nuclear Industry on SACADA Yung Hsien J. Chang, Ph.D.
