Overview

EN 45510-6-7:1998 (published by CLC) is a procurement guide that helps users prepare technical specifications for moisture separator reheaters used as turbine auxiliaries in electricity generating stations. The standard provides structured guidance for procurement documentation and contract preparation for moisture separator reheaters in conventional power stations. It is explicitly not applicable to equipment used within the nuclear reactor plant area, and other non-power-station applications were not considered in its development.

Key Topics

This guide focuses on the elements a clear technical specification should address. While it does not mandate design solutions, it highlights essential procurement topics such as:

• Scope and application - defining intended use within power station steam-cycle systems and exclusion of nuclear reactor plant area.
• Functional and performance requirements - expected operating conditions, moisture separation efficiency, reheating duty and integration with turbine steam paths.
• Design and materials - selection principles, corrosion resistance, mechanical integrity and compatibility with steam quality (as applicable).
• Interfaces and installation - mechanical and piping interfaces, required clearances, mounting and alignment considerations for turbine auxiliaries.
• Testing and inspection - factory and site tests, acceptance criteria, performance verification, and non‑destructive examination where relevant.
• Documentation and drawings - required drawings, data sheets, calculation records and manuals for operation and maintenance.
• Commissioning and handover - procedures, performance testing during commissioning and final acceptance.
• Safety, quality assurance and compliance - quality control, inspection regimes and relevant statutory or industry compliance expectations.

Note: The guide provides structured topics to include in procurement specifications but does not prescribe specific technical values or detailed engineering rules.

Applications

EN 45510-6-7 is intended for use when procuring moisture separator reheaters for:

• Steam turbines and combined-cycle power plants (conventional electricity generating stations)
• Plant owners and operators preparing tender documents
• Procurement and specification engineers developing contract requirements
• OEMs and suppliers responding to tenders
• Consulting and project engineering firms writing technical specifications or evaluating bids

Using the guide helps ensure clearer tenders, more comparable bids and reduced procurement risk for turbine auxiliary equipment.
