36、nt of condenser plants for use in electricity generating stations (power stations). This guide for procurement is not applicable to equipment for use in the nuclear reactor plant area of nuclear power stations. Other possible applications of such equipment have not been considered in the preparation

37、 of this guide. This guide covers: water cooled surface and direct contact condensers acting as a steam sink for main or auxiliary turbines in power stations (parts in brackets marked with * apply to direct contact condensers only); condenser auxiliary equipment. Air blast or air-cooled type condens

38、ers (ACCs) are not covered by this guide. The equipment covered by this guide is defined by its function rather than design type. Therefore, the guidance to the specification is stated in performance terms rather than being specified by a detailed description of the equipment to be supplied. This gu

39、ide indicates to potential purchasers how their specification should be prepared so that: the equipment type and capacity interfaces correctly with other elements of the systems such as the turbine, cooling water system, regenerating feed heating system, district heating and steam generating plant;

40、predicted performance is achieved; ancillary equipment is properly sized; reliability, availability and safety requirements are achieved; proper consideration is given to the evaluation process and the quality measures to be applied. This guide does not determine the type of specification (e.g. deta

41、iled, performance, functional) or the extent of supply for any given contract which is normally decided on the basis of the purchasers project strategy. It does not cover: any commercial, contractual or legal issues which are normally in separate parts of an enquiry; any allocation of responsibiliti

42、es which are determined by the contract. This guide does not prescribe the arrangement of the documents in the enquiry. NOTE As a comprehensive European environmental policy is still under preparation, this guide does not address the environmental implications of the equipment. 2 Normative reference
