AP1000核岛电气物项质量保证分级

Quality Assurance Category for Electrical Items in AP1000 Nuclear Island

AP1000核岛电气物项分为电气设备、电缆、电缆通道及通道支架几类,在核岛不同的区域,由于其安全级与抗震等级的不同,各类电气物项的质量保证分级也不同,同时有些物项的质量保证分级在采购和施工阶段也有所不同。论文综合阐述了AP1000核岛电气物项质量保证分级、安全级、抗震等级之间的对比关系,以案例的形式论证了此对比关系,并分析了AP1000电气物项质量保证分级的特点,最终形成AP1000核岛电气物项质量保证分级指导书,用于工程施工、采购和质量验收,避免工程浪费,提高工程质量。

There are amount of electrical items in AP1000 nuclear island such as electrical equipments, cable, raceway and raceway supports, the quality assurance category for these items are different in different areas and they have different safety class and seismic category.The quality assurance category may be different in procurement period and construction period even for the same item.This thesis expounds the comparison among the quality assurance category, safety class and seismic category and demonstrates this comparison through series of cases and also analysis the quality assurance category.In the end it concludes the guideline of quality assurance for electrical items in nuclear island and this can be used to perform construction, procurement and quality inspection work and avoid construction waste and improve quality.
