On Thursday of this week, the UK Office of Nuclear Regulation announced that the design proposed for the station -the \u201cHPR1000\u201d, originally known as the \u201cHualong-1\u201d has successfully completed the first, preparatory stage of the Generic Design Approval (GDA) process. This appears to have been completed on time, or perhaps a few weeks early.<\/p>\n<p>While we shouldn\u2019t over-state the importance of this particular transition \u2013 GDA is a four stage process, in which stages 2 &amp; 3 are where the great majority of the detailed evaluation of the design from a safety perspective is undertaken \u2013 it is important in that it\u2019s the first point at which the developers have to publish reasonably detailed data on the design.\u00a0That data is available <a href=\"http:\/\/www.ukhpr1000.co.uk\/documents-library\/step-2\/\" target=\"_blank\" rel=\"noopener\">here<\/a>.<\/p>\n<p>This piece is intended to give an overview of the design, highlighted particular strengths and weaknesses that may affect the GDA outcome, and giving a comparison against the virtues and vices of the other contenders for UK build.<\/p>\n<p>&#8230;click on the above link to read the rest of the article&#8230;<\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>China\u2019s \u201cHualong 1\u201d passes the first stage of the UK GDA process With little fanfare last week, the Chinese designed HPR1000 (previously Hualong-1), pressurised water reactor, cleared the first of four stages in the General Design Assessment (GDA) administered by the UK Office of Nuclear Regulation (ONR).
