    China to develop floating nuclear power plant
    27 October 2015

    The UK-based Lloyd's Register Energy and the Nuclear Power Institute of China (NPIC), a subsidiary to China National Nuclear Corporation (CNNC), have signed a "major cooperation framework agreement for a first-of-a-kind floating nuclear vessel" that will be used in Chinese waters to supply electrical power to offshore installations. Lloyd's Register Energy said in a statement that it would assist in the design and development of a "safe and secure floating vessel" containing a small modular reactor (SMR).

    The first contract under the framework agreement is to develop new nuclear safety regulations, safety guidelines and nuclear code and standards for the floating NPP (FNPP) that are consistent with offshore and international marine regulations and International Atomic Energy Agency (IAEA) nuclear safety standards. Lloyd's Register Energy helps clients design, construct and operate capital intensive assets to their highest levels of safety and performance, said nuclear director Mark Bassett. He said NPIC has asked Lloyds Register Energy to help them safely achieve this "technically challenging" offshore nuclear programme.

    Melvin Zhang, Lloyd's Register Energy's vice-president of strategic development for Greater China, said the agreement marks the beginning of a ground-breaking initiative for the Chinese nuclear industry, taking nuclear power generation offshore. He said the project will show how nuclear power can be used and applied to support sustainable power generation in both energy and marine sectors. NPIC said it believes there is "substantial opportunity" to further efforts in developing power generation for the future. This is just one example of how NPIC is seeking to innovate and apply new ways of using nuclear technology for robust power supply.

    NPIC designed and built China's first pressurised water reactor, its first high flux reactor, its first pulse reactor, as well as the Min Jiang Test Reactor. NPIC is involved in reactor design and safety research, and produces medical isotopes.

    The FNPP will be based on a 100MWe marine version of CNNC's ACP100 SMR design, an integrated pressurized water reactor with passive safety features, which has been under development since 2010. The preliminary design was completed in 2014. The ACP100 is a multi-purpose reactor designed for electricity production, heating, steam production or seawater desalination.

    China announced in June plans to put a FNPP into commercial operation by 2019. NPIC chief designer Song Danrong said station will have a 100MWe reactor unit of the domestic ACP100S design. The basic design will be completed in 2016, the project design will be ready in 2017 and the vessel carrying the station prepared, with the aim of completing the main component installation in 2018 and commercial operation in 2019, Song said. The station will be used to supply power to remote offshore areas or for deep-sea oil exploration projects. The demonstration project is expected to cost about CNY3.5bn (about $560m).

    CNNC New Energy Corporation, a joint venture of CNNC (51%) and China Guodian Corp, is planning to build two ACP100 units in Putian county, Zhangzhou city, at the south of Fujian province, near Xiamen, as a demonstration plant.

    In April, CNNC signed an agreement with the IAEA for a Generic Reactor Safety Review (GRSR) of the ACP100 which will review the completely- or partially-developed safety cases of new reactor designs that are not yet at the licensing stage. The review was scheduled to begin in July and expected to take seven months to complete.

    Russia is expected to provide some technical assistance. In June 2014, Rusatom Overseas, a subsidiary of Russia's state nuclear corporation Rosatom, signed a memorandum of intent with CNNC New Energy Corporation to design and build FNPPs and to promote small reactor technologies. Currently, the only FNPP nearing commissioning is the Akademik Lomonosov, under construction at the Baltiysky Zavod in St Petersburg.

    The vessel has two 35MWe reactors, based on those used to propel icebreakers, which are mounted on a barge to be moored at a harbour. Akademik Lomonosov is on schedule for delivery to Russian nuclear power plant operator Rosenergoatom in September 2016 for operation off the coast Chukotka in the northeast Arctic in 2017 or 2018. In late June, Rusatom Overseas (a branch of Rosatom) and China's CNNC New Energy signed a memorandum for building floating nuclear power plants. In July 2014, a Chinese visited Russia's FNPP Training Centre and the Baltiysky Zavod and met with members of the FNPP construction project team.

    ACPR50S small reactors developed by CGN to be operational by 2020

    [​IMG]
    ACPR small modular PWRs

    Not to be outdone by CNNC in the small modular field, CGN has two small ACPR designs: an ACPR100 and an ACPR50S, both with passive cooling for decay heat and 60-year design life. Both have standard type fuel assemblies and fuel enriched to <5% with burnable poison giving 30 month refueling. The ACPR100 is an integral PWR, 450 MWt, 140 MWe, having 69 fuel assemblies. Reactor pressure vessel is 17m high and 4.4 m inside diameter, operating at 310°C. It is designed as a module in larger plant and would be installed underground.

    The offshore ACPR50S is 200 MWt, 60 MWe with 37 fuel assemblies and two loops feeding four external steam generators. Reactor pressure vessel is 7.4m high and 2.5 m inside diameter, operating at 310°C. It is designed for mounting on a barge as floating nuclear power plant (FNPP) or possible submersible. The applications for these are similar to those for the ACP100, but the timescale is longer and none is expected on line before 2023.


    China to Build First Marine Nuclear Power Platform

    Chinese authorities have approved the construction of the country's first marine nuclear power platform.

    The demonstration project is sponsored by China Shipbuilding Industry Corporation, which began the R&D process in 2014.

    Military analyst Shi Hong explains the technology.

    "A marine nuclear power platform is a floating nuclear power plant, built on a mobile platform on the ocean. It can be very helpful for marine resource exploration, and life on small islands. It can provide energy for ocean water purification and electricity generation on islands. Such platforms can improve the quality of living on small islands tremendously."

    Marine nuclear power platforms can also provide safe and reliable energy for oceanic oil exploration.

    Shi Hong says beyond serving civil functions, the technology also has military applications.

    "The development of such nuclear power platforms can present new opportunities for war ships. Military ships have very high standards when it comes to employing nuclear energy. These platforms can serve as basic testing grounds to further develop new equipment and technology for military use."

    Two construction plans have been drawn up by the developer. One is for a power plant built on a mobile platform in the ocean. The other is for a submersible plant that can operate below the ocean surface under harsh conditions.

    Nuclear submarines and Nuclear powered Aircraft careers have floating nuclear power plant as well. the only difference is that its energy is used to move the platform and not to produce electricity.

    China mulls 20 floating reactor platforms to aid oil drilling

    China is planning to build about 20 floating reactor platforms to meet the demand of maritime atomic propulsion, driving a market that could be worth tens of billions of dollars, a report said on Thursday.

    The country's first-ever floating nuclear plant is about to start the final assembly in Huludao, a coastal city in Liaoning province, and it will be built by Bohai Shipbuilding Heavy Industry Co Ltd, a unit of China Shipbuilding Industry Corp, according to eworldship, a Shanghai-based maritime industry information provider.

    "CSIC is the first company with the permission to construct the floating nuclear-powered vessel, and it aims to become the strongest builder of floating nuclear platforms within five years," the report quoted Wu Zhong, general manager of CSIC Asset Management Co Ltd, as saying during an expert review held this week.

    Zhu Hanchao, deputy chief engineer of the CSIC 719 Research Institute, said that the average cost of a pilot project is about 3 billion yuan ($463 million), but it will be able to generate sales of 22.6 billion yuan in 40 years, the life span of the vessel. He said that the cost could go lower as the company realizes mass production of such platforms.

    The CSIC 719 was established in 2014 to develop a maritime nuclear power platform and core technologies in the field.

    At the end of last year, the shipbuilder got the nod from the National Development and Reform Commission, the country's top economic regulator, to start research for a demonstration project of the platform.

    Earlier this year, China General Nuclear Power Group signed a strategic cooperation agreement with CSIC to develop a reactor design-200-megawatt ACPR50S for the offshore nuclear power platform.

    CGN is currently working on the preliminary design for ACPR50S, which is expected to start construction in 2017 and be commissioned by 2020.

    The floating nuclear power plant, which can be equipped inside a section of the vessel, is often used to supply stable electricity not only to remote areas, but also to large industrial facilities such as seawater desalination plants and offshore oilfield exploration rigs, CGN said.

    "The project has a wide range of civilian applications in providing safe and stable energy for maritime resources exploration and development," CGN said.

    The offshore oil drilling demand will keep growing in the next five years with a market value of 100 billion yuan, while the industry of nuclear-powered equipment is expected to reach 50 billion yuan per year in the Bohai Bay, Wu Zhong said.

    Anyone can do that who has got key technologies.
    Play is of money and need. Neither India needs it, plus it's costly.
