Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If manual boron concentration control is used, then operator flexibility is maintained, but operator workload increases and control precision decreases
Solution Approach 1:
The control system automatically determines boron concentration control amounts and control rod operation amounts based on power change requirements, eliminating the need for manual operator calculation and prediction. The system serves itself by autonomously generating control commands without human intervention for the actual control decisions.
Solution Approach 2:
The system uses feedback from current power levels, boron concentration values, and control rod positions to continuously adjust and optimize control decisions. The control amount determination unit receives real-time operational data and adjusts control strategies based on actual system state, improving both precision and reducing operator burden.
2Measurement precision
If automated control systems are implemented, then control precision improves, but system complexity increases
Solution Approach 1:
The control system is divided into distinct functional units: a control amount determination unit that calculates required control amounts, a boron concentration control unit that executes boron adjustments, and a control rod control unit that manages rod positions. This segmentation allows each unit to specialize in specific tasks, improving overall control precision while managing complexity through modular architecture.
Solution Approach 2:
The control system integrates multiple control functions into a unified automated platform that handles both boron concentration control and control rod operations. The single automated system performs what previously required separate manual operations for boron management and rod control, reducing operational complexity despite increased automation capabilities.
3Manufacturing precision
If boron concentration is frequently adjusted, then power control accuracy improves, but operational stability may be compromised
Solution Approach 1:
The control amount determination unit calculates and prepares control commands in advance based on predicted power change requirements. By determining the necessary boron concentration adjustments and control rod movements before power changes occur, the system maintains operational stability while ensuring precise power control when changes are needed.
Solution Approach 2:
The system dynamically adjusts control strategies based on real-time operational conditions, power change rates, and system state. Rather than applying fixed control rules, the control amount determination unit adapts control parameters dynamically, allowing frequent adjustments when necessary for precision while maintaining stability during normal operating conditions.
