Construction Plant Certification

ISO-14000 certification The first international standard for environmental-quality management. It is not a compliance standard but consists of voluntary guidehnes for constructing a management system from start to finish to ensure that objectives for environmental compliance are set and met. Plant certification wiU provide evidence of proactive environmental management and wiU reduce their exposure to lawsuits and regulatory problems. See plastics cradle-to-grave. 

When a construction completion certificate has been signed for every contract, construction can be deemed to be complete for the whole plant. 

Certificate of Training Achievement for construction plant operators (CTA)... 

All aspects of the material s chemical, mechanical and physical properties which are included in the specification should be capable of measurement and certification. For critical duties all material supplied should be fully tested and certified by competent approved, independent test laboratories. All items of plant should be purchased with material certification. Additional certification is required in cases where the fabricator, in manufacturing an item of plant, used techniques such as welding or heat treatment which may affect the corrosion behavior of the construction materials. 

Although the duration of construction was influenced by various factors, including the accident at Three Mile Island, economic conditions and power needs, the history and trend of extended times to obtain operating licenses was a motivation for the development of an alternate licensing process, which is defined in 10 CFR Part 52. The licensing process in 10 CFR Part 52 involves the possible submittal of a nuclear power plant design for certification and the approval of specific sites via an... 

The Advanced Pressurized Reactor AP-600 (Westinghouse) final design certification by NRC is expected for 1998. A larger unit of an advanced PWR, the System 80+, with 1300 MW(e) is being developed by ABB/Construction Eng. [86]. These designs with enhanced passive safety features are pursued in the USA to provide additional electricity and replace retired plants. 

During HR-5 construction, main design features and safety concepts of the NHR have been reviewed and approved by the Chinese National Nuclear Safety Administration (NNSA). The HR-200 design is based on the HR-5 practice. Their main design features are the same. Therefore the HR-200 will be licensable. Up to now the first HR-200 plant siting report and environmental impact assessment report have been reviewed and approved, the design certification of INET for NHR has been also released by National Nuclear Industrial Co. (NNIC), and the review on the preliminary safety analysis report is under way. 

A 1/3-scale integral test facility has already been constructed and operated to assess plant safety and to benchmark codes. Because of its small size, a full-scale nuclear prototype could be built and tested at a relatively low cost, if required and accepted for certification. 

The first APIOOO plant is already under construction in China. The design has also undergone design certification by the United States (US) Nuclear Regulatoiy Commission (NRC), albeit with some work still ongoing. This assessment shows that the design and development process of the APIOOO led to outcomes that are consistent with UK ALARP expectations. 

Section 8, page 22 on modifications). The construction team should give reasonable warning of their intention to offer the plant for mechanical acceptance and preliminary reservation lists, which include safety item.s, must be drawn up. A typical check-list is shown in Appendix 3.1 (page 89). In this way, many items can be cleared up informally. At handover, the plant should be checked line by line, valve by valve, against the Approved for Construction prrx s and instrumentation di ams

ensure that the plant meets the design intent. Die formal handover usually has a certificate with the final reservation hst of remedial work requited. It is most imponant that the plant is handed over in a safe condition, correctly built and to design.
