0 L TEC Purpose and Outcome l r\\l H KN A TI ON A L Purpose To provide a high-level overview of the SMR-160 Human Factors Engineering (HFE) milestones and discuss the HFE lmplementatio Plans.

Outcome To obtain feedback from the NRC staff on the HFE implementatio plans and examples of OER, FRA/FA and TA elements.

Overview of HFE Program

  • 1.* 0 L T E C Ir,, r~KN A llO NA L The Human Factors Engineering (HFE) program is being implemented according to NUREG-0711 and related regulatpry requirements.

The first element is the Program Plan which is HOLTEC procedure HPP-160-1014.

The schedule is proprietary and will be discussed during th closed session.

Overvievv of HFE Program ( cont'd)

This procedure contains 11 Appendices - one for each of th other elements of the HFE program.

O LT EC ll'\\ITEl<NA TI ONA L Each Appendix represents the Implementation Plan for one !of the HFE program elements.

Question: How do we submit the Implementation Plans (procedure HPP-160-1014) for NRC review and feedback?

HFE Issues Tracking OLTEC INITEK NA TIO NA L HFE issues are identified and tracked in the HFE Issue Trackirg System (HITS), which is a web-based database. HFE issues include:

known industry issues (typically identified in the OER) issues identified in one of the HFE program elements human engineering discrepancies (HED) identified during the HFE design (typically during the V&V process) issues identified during HSI design issues identified via simulator modeling

OER Scope The OER scope includes reviews of the following inputs:

predecessor and related plants and systems recognized industry H FE issues related HSI technology issues identified by plant personnel important human actions (IHAs)

OER Priorities The three priorities are defined as:

O LTEC E l< NA T I ON A L Priority 1 issues are high priority and need to be addressed. Tmese must have a documented way it is addressed. If it has not bee addressed yet, it must be in the HITS database with a high pri rity.

Priority 2 issues are moderate priority and should be assessed to determine if they should be addressed. If the issue has not been addressed yet, it should be in the HITS Database.

Priority 3 issues are low priority and normally not considered.

These issues are documented in the OER report but not entered into the HITS Database.

OER Documentation The OER report includes:

0 LT EC I N/TEKNA T I ON A L The sources of information and methodology used to perform! the OER Description of how the OER was conducted A list of the GER-identified issues that have been or will be incorporated including any open issues from the HITS

FRA/FA OLTEC lr'l!TEKNAT I ONAL The Functional Requirements Analysis and Function Allocatipn (FRA/FA) defines the plant's high-level functions of safety and power production and allocates the actions to human and system resources:

Establish a description of the plant functions that are required to operate the plant Establish the inter-relationships between plant functions Describe the allocation assignment of functions Assess the adequacy of functions against operational and human needs

FRA/FA Process Step 1: Plant Function Identification and Decomposition is performed for overall plant design to identify all the plant functions required to accomplish plant goals.

OLTEC EK N A TI ON A L Step 2: Functional Requirements Analysis is done for each high-level function associated with the system, the requirements are identified, and the results are captured in the Function Description Form.

Step 3: Function Allocation divides the system functions identified in the previous steps into actions, evaluated, and allocated as automatic, manual, or shared control.

TA Process e ~~N~T,~

The Task Analysis (TA) takes Human Actions (HA) identified i the FRA/FA and other HFE program elements and further analyzes them to identify the tasks that personnel must perform to accomplish the HA.

Task analysis encompasses a range of plant operating conditions, including startup, normal operations, abnormal operations, transient conditions, low power, shutdown, and refueling conditions.

TA Process ( cont'd)

The task analysis includes four major steps:

1) Identify and Define Tasks - gathers the HAs to be analyzed an defines tasks that encompass all the HAs.
2) Develop Task Descriptions - develops task descriptions, whic include attributes about the task O LT EC 1Nl E K N A TI ON A L
3) Analyze Tasks - refines the Task Descriptions to include enoufkh detail to allow requirements to be developed
4) Identify Requirements - identifies task requirements such as:

information, controls, alarms or other support needed to perrorm the task; K&A required; workload estimates; and constraints

O LTEC TA Process (cont'd) ll'!TEKN A T I O NA L Each task contains 3 elements:

1) Task Description Form documenting the HAs and task attribul!es
2) Task Analysis identifying specific tasks, subtasks and actions t perform the function containing HAs
3) Operational Sequence Diagram (OSD) to graphically shows th relationship between personnel and automated actions

0 L TEC S&Q lr!JTEKNATIO NA L The Staffing & Qualification (S&Q) is applicable licensed operator defined in 10CFRSS or optimized for SMR-160.

The SMR-160 intends to seek an exemption to the staffing guidante in 10 CFR 50.54(m) based on results of the HFE V&V and validation testing of the staffing plan. Currently no operator actions are credlited for DBAs with a digital control system containing defense-in-dept monitoring, tiered alarm system and computerized procedures.

Question: How is the workload scenario(s) for the unaffected unit determined?

OER, FRA/FA, TA examples

-,, _, *.1.* 0 L T E C l/'llTl:KNATION A L Some OERs have been prioritized with examples for each priority ( 1, 2, and 3).

The initial FRA/FA for major systems are complete.

Some TAs for completed FRA/FAs have been prepared.

Question: How do we submit examples of completed OERs, FRA/FAs and TAs for NRC review and feedback?

OLTEC TAV&V lriJTEKN A T I O N,\\L Once the desktop simulator is ready, the HFE Verification &

Validation (V&V) will begin.

The HFE V&V will be used as part of the plant referenced simulator (PRS) testing and qualification.

HOLTEC will use qualified Subject Matter Experts (SM Es) for simulator testing, including HFE V&V.

Siniulator Testing per ANSI/ ANS-3.5 0 LT EC lr\\lHl<N A fl ON A L ANSI/ANS-3.5-2018 will be used to perform simulator testin_.

Section 5.1 provides details for initial construction.

Question: Reg Guide 1.149 endorses the 2009 version, can we use the 2018 version?

Question: Section 5.1 implies that an SME can verify the simulator configuration. What training documentation is required for an SME?

Simulator Configuration Control OLTEC l ~ T E K NA T I ON A L HOLTEC will have a configuration control program in place t track plant (design) and simulator changes following declaration of a PRS.

Question: Will the NRC want to see a configuration control program during simulator development? How about after HiFE V&V but prior to declaring a PRS?
