37、writing the technical specification for the procurement of high pressure piping systems 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 applicati

38、ons of such equipment have not been considered in the preparation of this Guide. This Guide covers: - Live steam lines - Hot reheat lines - Cold reheat lines - Feedwater lines - Spray water lines for HP and RH-attemperators and steam-bypass-systems - Pump minimum flow and balancing leak off lines -

39、Auxiliary steam supply lines - Condensate lines - Safety valve discharge pipelines - Bled steam pipelines - Steam and water drains, vents and warming lines The equipment covered by this Guide is defined by its function rather than design type. Therefore, the guidance to the specification is stated i

40、n performance terms rather than being specified by a detailed description of the equipment to be supplied. This Guide 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; - pre

41、dicted performance is achieved; - ancillaty 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.9. d

42、etailed, 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 pars of the enquiry; - any al/ocation of respons

43、ibi/ities 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 envimnmental implications of the equipment 2 Normative ref
