Non-Proprietary ABSTRACT This document describes the conceptual design of the Advanced Power Reactor 1400 (APR1400) Basic Human-System Interface (HSI), which establishes the generic indication, alarm, control and procedure methods applied to all systems and functions controlled from the main control room (MCR) and the remote shutdown room (RSR). These same HSI methods apply to the safety parameter display system (SPDS) indications provided in the MCR and the technical support center. The APR1400 Basic HSI also defines indication, alarm, and control methods for local control stations used for important human actions (IHA).

The APR1400 Basic HSI (also referred to as Basic HSI) is derived from the Basic HSI of the APR1400 predecessor design, Shin Kori nuclear power plant units 3 and 4 (SKN 3&4). The Basic HSI for SKN 3&4 reflects an evolution from previous operating plants in Korea and around the world. The APR1400 Basic HSI reflects changes from SKN 3&4 primarily for compliance to US regulatory criteria. The conceptual design of the APR1400 Basic HSI, as described in this document, is the starting point for development of the complete APR1400 Basic HSI, which is developed during the Human Factors Engineering (HFE)

Human-System Interface Design (HD) program element (PE). The HD PE is described in the HD implementation plan (IP) (Reference 5).

Section 1 of this document defines the purpose of the Basic HSI and the purpose of this document.

Section 2 establishes the scope of the Basic HSI. Section 3 provides an overview of the Basic HSI conceptual design. Section 4 provides the details of the conceptual design. Section 5 describes the history and design process that lead to the Basic HSI. Appendix A demonstrates compliance of the design to the NUREG-0711 Review Criteria for the HD PE.

PURPOSE This document describes the APR1400 Basic HSI, which establishes the generic indication, alarm, control and procedure methods applied to all systems and functions controlled from the main control room (MCR) and the remote shutdown room (RSR). These same human-system interface (HSI) methods apply to the safety parameter display system (SPDS) indications provided in the technical support center (TSC). The APR1400 Basic HSI also defines indication, alarm, and control methods for local control stations (LCS) used for important human actions (IHA). The APR1400 Basic HSI ensures the same HSI design is consistently applied throughout the plant systems of APR1400 and at the HSI locations credited for controlling the critical safety functions (CSF) and critical power production functions (CPPF) defined by the human factors engineering (HFE) functional requirements analysis (FRA), during normal and degraded HSI conditions.

This document describes the conceptual design of the APR1400 Basic HSI which includes, by reference, the APR1400 Style Guide (Reference 1) (also referred to as Style Guide). The Basic HSI concept includes the HSI accommodations for the plants operating staff, such as the ergonomic designs of operator consoles (OC) and the safety console (SC), and their architectural configuration to ensure visibility and hearing for crew coordination. The Basic HSI concept also defines the criteria and methods for spatially dedicated and continuously visible (SDCV) HSI, the methods for safety and diverse HSI, and the strategies for managing degraded HSI.

The implementation plan (IP) for the HD PE (Reference 2) governs the evolution of the APR1400 Basic HSI concept into the complete APR1400 Basic HSI detailed design through documentation of detailed functional designs, prototype development, and design tests using United States (US) licensed reactor operators.

All figures in this document that show video displays or control panel layouts depict the design standards of the Style Guide and the design basis inventory content of the Basic HSI. But the actual HSI inventory for the video displays and control panels for the APR1400 Human System Interface System (HSIS) will reflect the APR1400 plant design. For example, the typical large display panel (LDP) shown in Figure 3-3 employs the graphical standards of the Style Guide and the design basis content of CSFs and CPPFs (and their preferred normal and emergency success paths). However, the actual APR1400 LDP will reflect the CSFs and CPPFs for APR1400 (and their preferred normal and emergency success paths).

Therefore, the APR1400 LDP graphic may have a different inventory and mimic configuration than the graphic shown in Figure 3-3. The design of all APR1400 displays and control panels is based on the Style Guide criteria and the analyses of personnel roles (job analysis), and systematic strategies for organization, such as arrangement by importance, and frequency and sequence of use.

SCOPE The APR1400 Basic HSI encompasses the physical design of the MCR, which includes OCs, the SC, the LDP, and furnishings such as bookcases and worktables. The APR1400 Basic HSI defines the generic methods for controls, alarms, information displays, and procedure displays. These generic HSI methods are applied to Basic HSI functions, such as computer-based procedures (CBP), critical function monitoring (CFM), success path monitoring, accident monitoring instrumentation (AMI), and bypassed and inoperable status indication (BISI). All Basic HSI functions are seamlessly integrated through Basic HSI features such as the information display hierarchy, single point alarm acknowledgment, intuitive diagnostic drill down and inter-function navigational hyperlinks. These physical and functional resources constitute the APR1400 Basic HSI, within which the HSI inventory for the APR1400 design is implemented.

The scope of the APR1400 Basic HSI includes:

The design basis (i.e., the HSI inventory selection criteria) for SDCV indications and alarms to be displayed on the non-safety LDP and safety related displays.

The design basis for SDCV controls and their location within the HSI facilities.

The methods (e.g., dynamic video symbols, conventional HSI components) for all displays, alarms and controls, including distinctions required to accommodate safety HSI, diverse HSI, and LCS HSI.

Criteria for alarm applicability and prioritization, and the display and control methods for alarm states and priorities.

Design criteria for graphic displays including density, graphic symbol and character size, line thickness, and information orientation (as defined in the Style Guide).

The video display hierarchy, including the function, task and system design content of each hierarchical level.

The navigation methods between and within hierarchical display levels, and between alarms, displays, controls and CBPs.

CBP methods, including navigation within and among procedures, place keeping, annotations and bookmarks, multiple procedure usage, independent step verification, archiving, automated data checking, and provisions for continuous action steps.

Configuration of OCs and the SC, and their arrangement within the HSI facilities.

Methods for control transfer between HSI facilities.

Nomenclature and labeling standards for all elements of both soft and conventional HSI, including abbreviations and syntax for labels and alarm messages.

The APR1400 Basic HSI includes the APR1400 Style Guide. This document defines the design standards for visual display unit (VDU) and conventional HSI devices, including screen and panel layout standards, visual coding standards (e.g., shapes and colors) and all alphanumeric styles.

While the Style Guide establishes the format and fonts for labels used on all HSI elements, the APR1400 Nomenclature and Labeling Guide establishes the naming, abbreviations, acronyms, numbering and syntax rules for components of the plant used by plant operators. This includes:

Basic Human-System Interface APR1400-E-I-NR-14011-NP, Rev. 2 KEPCO & KHNP 3

Non-Proprietary HSI components Room and plant area labels Instrumentation and control (I&C) and electrical cabinet labels Labels for components in plant systems (e.g., pumps valves)

For examples, since it is not practical to use complete English names and complete identification numbers for all labels, this guide defines the portions of names and numbers used on all media (soft and conventional nameplates) and at all hierarchical levels to ensure distinct unambiguous labeling. This guide also defines standard syntax and rules for alarm titles and messages to minimize the need for unique operator training and promote clear and rapid operator understanding. The Basic HSI Nomenclature and Labeling Guide is not part of the Basic HSI conceptual design, but is developed as part of the Basic HSI detailed design during the HSI design (HD) program element (PE).

APR1400 Basic HSI also establishes standard functional specifications for the indications and controls associated with plant instrumentation and components. This is referred to as the APR1400 Basic HSI Component Control and Instrumentation Design Guide. This guide ensures HSI and control method consistency across all APR1400 plant systems. The Basic HSI Component Control and Instrumentation Design Guide is not part of the Basic HSI conceptual design, but is developed as part of the Basic HSI detailed design during the HD PE.

All LCSs employed for IHAs are designed in accordance with the Style Guide, the APR1400 Nomenclature and Labeling Guide and the APR1400 Basic HSI Component Control and Instrumentation Design Guide.

The same SPDS information displayed in the MCR and TSC, as defined by the Basic HSI, is also transmitted to the Emergency Operation Facility (EOF) for display within the EOF HSI system. The EOF HSI system and the EOF physical configuration design are outside the scope of the APR1400 Basic HSI.

DEFINITIONS APR1400 Basic HSI The generic indication, alarm, control and procedure methods applied to all systems and functions controlled from the MCR and the RSR. These same HSI methods apply to the SPDS indications provided in the MCR and the TSC. The APR1400 Basic HSI also defines indication, alarm, and control methods for LCSs used for IHAs.

APR1400 HSI Design The complete integration of the APR1400 HSIS and APR1400 HSI Facilities (see definitions below).

APR1400 HSI Facilities The APR1400 MCR, RSR, TSC and LCSs. The facility designs accommodate the APR1400 HSIS (see definition below) as well as storage, communication, meeting and other habitability features important to support required operating crew performance, during all facets of plant operation.

APR1400 HSIS The specific soft and conventional indications, alarms, controls and operating procedures that encompass the HSI inventory defined by the TA PE and APR1400 plant system designs, within the generic HSI methods defined by the APR1400 Basic HSI.

Basic Human-System Interface APR1400-E-I-NR-14011-NP, Rev. 2 KEPCO & KHNP A1 Non-Proprietary Appendix-A NUREG-0711 REV. 3 REVIEW CRITERIA COMFORMANCE TABLE NUREG-0711 Rev. 3 Review Criteria Section and Paragraph 8.4 Review Criteria 8.4.1 HSI Design Inputs (1) Analysis of Personnel Task Requirements - The applicant should use the following analyses, performed in earlier stages of the design process, to identify requirements for the HSIs:

See HD IP

Operational Experience Review - An input to the HSI design should encompass lessons learned from other complex human-machine systems, especially predecessor designs and those involving similar HSI technology.

Functional Requirements Analysis and Function Allocation - The HSIs should support the roles of personnel in the plant, e.g., appropriate levels of automation.

Task Analysis - The set of requirements to support the role of personnel is provided by task analyses that should identify:

tasks needed to control the plant during a range of operating cond itions from normal through accident conditions detailed information and control requirements (e.g., requirements f or display range, precision, accuracy, and units of measurement) task support requirements (e.g., special lighting and ventilation re quirements) important HAs, as defined in Section 7 of this document, that sho uld be given special attention in the HSI design process

Staffing and Qualifications - The findings from analyses of staffing/qualifications should provide input for deciding upon the layout of the overall control room and allocating controls and displays to individual consoles, panels, and workstations.

The staffing/qualifications analyses establish the basis for the minimum and maximum number of personnel to be accommodated, and requirements for coordinating activities between them.

(2) System Requirements - The applicant should identify any constraints on the HSI design imposed by the overall I&C system, e.g., constraints on the information that can be presented due to sensor data availability.

(3) Regulatory Requirements - The applicant should identify the applicable regulatory requirements as inputs to the HSI design process.

3.5.2 (items 4-6), 4.6, 4.7.1.4, 4.14, 4.17 (4) Other Requirements - The applicant should identify any other requirements, such as customer requirements, that are inputs to the HSI design.

Basic Human-System Interface APR1400-E-I-NR-14011-NP, Rev. 2 KEPCO & KHNP A2 Non-Proprietary NUREG-0711 Rev. 3 Review Criteria Section and Paragraph 8.4.2 Concept of Use and HSI Design Overview (1) The applicant should develop a concept of use stating the roles and responsibilities of operations personnel based upon anticipated staffing levels. The concept of use should:

provide a high-level description of how personnel will work with H SI resources address the coordination of personnel activities, such as interactio ns with auxiliary operators and the coordination of maintenance a nd operations Additional Information: Examples of the types of information the applicant may identify include the allocation of tasks between the main control room or to local control stations, whether personnel will work at a single large workstation or at individual ones, to what types of information each crew member will have access, and what types of information will be displayed to the entire crew.

3.4, 3.5 including all subsections (2) The applicant should provide an overview of the HSI, covering the technical bases demonstrating that they constitute a state-of-the-art HSI design supporting personnel performance. These bases may include analyses of operating experience and the literature, tradeoff studies simultaneously considering multiple alternatives, and engineering tests and evaluations. The overview should include a description of:

facility layouts, including workstations, large screen displays, and t he nominal staff working positions key HSI resources and their functionality, such as alarms, display s, controls, computer-based procedures, and other support and jo b aids technologies to support teamwork and communication within the main control room and between the main control room, the remote shutdown facility, the TSC, EOF, and local control stations the responsibilities of the crew for monitoring, interacting, and ove rriding automatic systems and for interacting with computerized pr ocedures systems and other computerized operator support syste ms 3.0 including all subsections, 4.8, 4.11.4, 4.11.5 including all subsections 8.4.3 HFE Design Guidance for HSIs Applicants should employ design-specific HFE design guidance in designing the features of the HSIs, their layout, and environments.

Although design guidance documents are called by different names, NUREG-0711 refers to them as style guides. Applicants may use one or more individual documents to serve this purpose. The HFE guidelines in NUREG-0700 may serve to support the NRC staff's review of the guidance in an applicant's style guide.

3.6 (see separate Style Guide)

(1) The topics in the applicants style guide(s) should address the scope of HSIs included in the design, and address their form, function, and operation, as well as the environmental conditions in which they will be 4.0 including all subsections

Additional Information: NUREG-0700 lists HSI topics around which a style guide(s) may be organized.

(2) The guidance in the applicants style guide(s) should be developed from generic HFE guidance and HSI design-related analyses. It should be tailored to reflect the applicants design decisions in addressing specific goals of the HSI design.

Additional Information: Analyses related to the HSI design might include an evaluation of recent literature, analysis of current industry practices and operational experience, tradeoff studies, and the findings from design-engineering experiments and evaluations.

5.0 (3) The individual guidelines in the applicants style guide(s) should be expressed precisely and describe easily observable HSI characteristics, such as Priority 1 alarms are shown in red. The guidelines in the style guide(s) should be sufficiently detailed so that design personnel can deliver a consistent, verifiable design meeting the applicant's guidelines.

3.6 (see separate Style Guide), 4.15.1 (4) The applicants style guide(s) should contain procedures for determining where and how HFE guidance will be used in the overall design process. They should be written so designers can readily understand them; the text should be supplemented with graphical examples, figures, and tables to facilitate comprehension.

See HD IP and Style Guide (5) The applicant should maintain the style guide(s) in a form that is readily accessible and usable by designers, and is easily modified and updated as the design matures. The guidance should include a reference(s) to the source upon which it is based.
