Solution Overview

Problem

In power plants with fusion reactors, operators face challenges in managing and monitoring numerous parameters simultaneously, leading to information overload and the need for enhanced notification systems to prioritize critical conditions effectively.

Innovation Solution

A modular power plant notification system that uses a tiered hierarchy of notifications (alarms, warnings, notices, and status indicators) displayed via traffic lights on user interfaces, with audible alerts and visual indicators to prioritize and filter information, ensuring operators focus on immediate actions while minimizing confusion.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Measurement precision

If continuous monitoring of numerous parameters is implemented, then measurement precision is improved, but information overload occurs and operator workload increases

Engineering Contradiction:
Improvemonitoring precisionVSAvoidoperator workload
Core Design Contradiction:
Measurement precisionVSEase of operation

Solution Approach 1:

The notification system segments information into four distinct tiers (alarms, warnings, notices, and status indicators) based on criticality. Each tier is visually differentiated using color-coded traffic lights (red, yellow, green, and blue respectively), allowing operators to quickly assess and prioritize information without being overwhelmed by the volume of monitored parameters.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The notification system acts as an intermediary between the complex monitoring data and the operator. It processes raw parameter data through automated classification and presentation logic, transforming numerous individual parameter readings into synthesized notification categories that highlight only the most relevant information requiring operator attention.

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If comprehensive parameter monitoring is implemented, then reliability is improved, but device complexity increases

Engineering Contradiction:
Improvesystem reliabilityVSAvoidnotification system complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The notification system divides comprehensive monitoring data into four hierarchical tiers based on criticality. This segmentation allows the system to maintain comprehensive monitoring capability while presenting simplified, organized information that reduces perceived complexity for operators.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system uses color-coded traffic lights (red for alarms, yellow for warnings, green for notices, blue for status indicators) to visually encode the criticality of different notification tiers. This color-coding system provides an intuitive, rapid method for operators to assess system state without complex analysis.

Inventive Principle:
Principle #32Color changes

3Loss of information

If detailed information is presented to operators, then information completeness is improved, but information overload occurs

Engineering Contradiction:
Improveinformation completenessVSAvoidinformation processing
Core Design Contradiction:
Loss of informationVSEase of operation

Solution Approach 1:

Information is segmented into four criticality-based tiers that preserve complete monitoring data while organizing it by importance. Operators receive all information but presented in a hierarchical structure that allows rapid prioritization, maintaining information completeness while enabling efficient processing.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The system provides more information than traditionally displayed (excessive action) but organizes it through selective emphasis using the four-tier hierarchy. This allows operators to access complete information when needed while focusing attention on only the most critical items during normal operation.

Inventive Principle:
Principle #16Partial or excessive action

AI summary

Embodiments are directed to configuring, providing, and managing notifications to one or more operators or personnel of a power plant. The power plant may be a modular power plant that includes one or more power module (PM) assemblies. In some embodiments, the PM assemblies may include a nuclear reactor that has a reactor core that generates at least one of heat, pressure, or radioactivity. The PM assembly may be included in a PM assembly array included in a modular power plant, such as a modular nuclear power plant. The notifications are in regards to the real-time, or near real-time, status or condition of the operation of the power plant. The notifications aid the operators and/or plant personnel in understanding the current status of the plant operation and promote plant safety, while minimizing information duplication, noise, confusion, and information overload for the operators. The notifications may be prioritized.
