Overview

EN 45510-6-9:1999 is a European standard developed by CLC, providing essential guidance for the procurement of main and auxiliary cooling water systems in electricity generating stations, specifically for turbine auxiliaries. This guide is intended to support the accurate and comprehensive drafting of technical specifications during the procurement process, ensuring that equipment and systems for cooling water applications in power stations meet high operational and quality requirements. It is important to note that this standard does not apply to cooling water equipment used in the nuclear reactor plant areas of nuclear power stations.

Key Topics

The standard covers a range of critical components and considerations for cooling water systems in power station environments:

• Pump intake screening plant: Including both coarse and fine screens, along with cleaning systems to remove debris and maintain water quality.
• Pressure filters: Guidance on selection and specification to ensure water purity and safeguard downstream equipment.
• Pipework and valves: Recommendations for material selection, system layout, and integration to optimize flow and reliability.
• Penstock gates: Requirements for operational reliability, safety, and compatibility with the cooling water infrastructure.
• Priming and venting equipment: Essential details to ensure proper system start-up, prevent air locks, and maintain efficiency.

This guidance ensures that each element of the cooling water system is specified to achieve safe, efficient, and long-term operation within the demanding environment of a power station.

Applications

The guidance of EN 45510-6-9:1999 is widely relevant for stakeholders involved in the procurement, design, and operation of power station equipment, specifically in the context of turbine auxiliaries and cooling water systems. Key practical applications include:

• Specification Development: Assists engineers and procurement teams in preparing clear, comprehensive technical documents for tendering and contract purposes.
• Supplier Evaluation: Provides a standardized framework for evaluating and comparing suppliers’ proposals and technical solutions.
• Operational Reliability: Enhances the reliability and performance of cooling water systems by promoting best practices in system design, component selection, and installation.
• Risk Reduction: Reduces the risk of system failures, maintenance issues, or inefficiencies arising from vague or incomplete technical specifications.

By adhering to this standard, power station operators and equipment suppliers can minimize procurement ambiguities and ensure robust, compatible installations that meet industry expectations for performance and safety.

Related Standards

For comprehensive compliance and integration, the following standards are also relevant:

• EN 45510 series: Covers procurement guides for various power station equipment categories, supporting harmonized technical documentation across all systems.
• IEC 60045 series: Relates to specification and performance standards for steam turbines and related auxiliaries.
• ISO 9001: Quality management systems, ensuring that suppliers maintain consistent quality in products and services.
• EN 1092: Standards for flanges and their joints-applicable in the design and operation of pipework and valve assemblies in cooling water systems.

Summary

EN 45510-6-9:1999 offers valuable guidance for the technical specification and procurement of turbine auxiliary cooling water systems in electricity generating stations. Applying this standard supports effective, efficient, and safe power station operations, making it an essential resource for power generation professionals focused on quality and long-term value.
