Open Source Software: LOGOS: Pioneering Optimization Software for Nuclear Power Plant Efficiency

In an era where operational efficiency and cost reduction are paramount in the nuclear energy sector, LOGOS emerges as a critical tool. This sophisticated software package leverages discrete optimization models, including deterministic and stochastic algorithms, to streamline capital budgeting processes. It's designed to tackle the complex challenges of Equipment Reliability (ER) and Asset Management (AM) in Nuclear Power Plants (NPPs), ensuring optimal resource allocation for improved safety and economic performance.

Historically, NPPs have grappled with balancing the reliability and availability of plant Structures, Systems, and Components (SSCs) against the backdrop of rising Operation and Maintenance (O&M) costs. The industry's shift towards value-based maintenance (VBM) under the Delivering the Nuclear Promise initiative highlights the pressing need for innovative approaches to sustain competitiveness. LOGOS addresses this need by providing a comprehensive solution that reduces labor-intensive processes and capitalizes on data analytics to cut costs and enhance engineering effectiveness.

LOGOS incorporates discrete optimization models based on advanced knapsack algorithms to address capital budgeting optimization challenges. With capabilities to manage both deterministic and stochastic data, LOGOS offers unparalleled flexibility in handling uncertainties in cost, reward, and constraints. Its integration with the RAVEN code facilitates data uncertainty propagation and sensitivity analysis, allowing for a customized workflow that aligns with specific user requirements. This enables NPPs to balance SSC reliability and cost efficiency optimally.

Advantages:

• Cost-Effective Operations: Minimizes O&M costs while maintaining or enhancing plant safety and reliability.
• Advanced Data Analytics: Employs state-of-the-art optimization methods to analyze and utilize ER and AM data effectively.
• Customizable Workflows: Interfaces with RAVEN for tailored data generation and analysis, fitting unique operational needs.
• Risk Integration: Combines economic and reliability risks in a single analysis framework for informed decision-making.
• Flexibility: Supports deterministic and stochastic input data, accommodating various uncertainty levels in decision processes.

Applications:

• Maintenance Optimization: Enhances ER programs by optimizing maintenance schedules based on reliability data and cost analysis.
• Optimal Component Replacement: Streamlines AM by determining the most cost-effective component replacement schedules.
• Budget Allocation: Maximizes profit by identifying the optimal set of projects within budget constraints.
• Operational Efficiency: Aids in achieving a balance between SSC reliability and availability, reducing operational costs.
