    Karachi Nuclear Power Complex (K2, K3 Reactors) --- 2,200 MW ..... U/C


    Recently PAEC signed a contract for 1100 MWe plant at Chashma i.e C-5. That too is in limbo as govt is not releasing funds. Before K-4/K-5 and Muzaffargarh plants, C-5 first will be built as Chinese are very keen to build that first.
    Debt is paid by respective plants not by govt. I guess govt only gives sovereign guarantee.
    Update on k-2/3: Commissioning are scheduled to start from July this year for k-2 but Wapda has not yet laid the transmission lines for the project.
    Contractual completion of k-2 project: 20 Aug, 2020 (60 months construction period) and for K-3: Aug, 2021. But there will definitely be delays. Project is divided into 3 categories. A cat construction/design by Chinese, B to be constructed by Pak companies and designed by china and C to be constructed and designed by Pak. C cat only includes mess etc type buildings.

    nuclear power is expensive..i think coal and hydro should be more on pirority for pakistan which has no coal usage
    by comparison even after "green revolution" india will still be using 55% of power via coal

    also we are already entering a capcity surplus era

    China installs outer dome on Hualong One reactor in Karachi


    [​IMG]

    SHANGHAI: China has finished building the outer safety dome at its first overseas “Hualong One” nuclear reactor in Karachi, with the project scheduled to be finished by the end of 2020, the China National Nuclear Corp (CNNC) said late Tuesday.

    China is hoping to use its third-generation Hualong One design to boost its presence in the overseas nuclear power sector and it is already making plans to build projects in Argentina and Britain, international media reported. The steel dome — measuring about 53 metres in diameter and over 23m in height, and weighing about 366 tonnes — was placed upon the top of the containment building walls at 8:06am yesterday, China National Nuclear Power (CNNP) has announced.

    The Hualong One uses a double-layer safety shell design. Together with the inner protective dome, the outer dome protects the reactor and prevents the release of radioactive materials into the environment in the event of a serious accident. "The successful hoisting of the outer safety dome has marked the end of the main structural project of the nuclear power plant, which has created favourable conditions for the overall test and thermal test of the subsequent containment," CNNP said.

    China developed the Hualong One reactor as a rival to the Westinghouse-developed AP1000 and Europe’s “Evolutionary Pressurised Reactor”, with both models beset by cost overruns and construction delays.

    The world’s first Hualong One reactor is set to go into operation ahead of schedule in the southeast Chinese province of Fujian late next year. CNNC said its four demonstration projects in China and Pakistan are progressing in an orderly manner, noting that they “are the only third-generation pressurized water reactor projects in the world that are being constructed on schedule.”

    Karachi 2 and 3 are the first export of China's Hualong One design, with construction of unit 2 beginning in 2015 and unit 3 in 2016. Installation of the reactor internals at unit 2 was completed in January this year. The units are scheduled for commercial operation in 2021 and 2022, respectively.

    great news

    but those Chashma plants at 320MW and 340MW should have been 1,000 MW units

    our total capacity should be >10,000 MW for nuclear

    its clean way of producing energy

    only question remains, how exactly is Pakistan going to decommission these plants

    Chashma 5

    In November 2010 the PAEC is reported to have signed a construction agreement with CNNC for a fifth unit at Chashma. In February 2013 a further agreement was signed by PAEC with CNNC for a 1000 MWe unit at Chashma. It was reported that China expected that this deal would be controversial under the NPT and guidelines of the NSG. Early in 2013 CNNC confirmed its intention to build a 1000 MWe class reactor, and said it would be an ACP1000 unit, though not necessarily at Chashma. The status of any continuing plan for Chashma 5 is very uncertain, and it may have been displaced by plans for a plant near Multan in southwest Punjab. Certainly it has been overtaken by the Karachi Coastal power project.

    we need a NPP at Gawadar, Turbat or Pasni... whatever site is feasible... We should built max number of NPPs near the sea so as to prevent usage of fresh water. Just built high tension wires running from north to south, south to west and south to north. If possible a sea canal can be built till Kotri for a similar NPP near Hyderabad and also for possibly drinking water.

    Outer dome installed on Hualong One reactor in Karachi

    The outer containment dome of the Karachi unit 2 nuclear reactor in Pakistan was successfully installed.

    The installation of the outer containment dome of Karachi unit 2, the first export of China's Hualong One pressurized water reactor design, will be followed up by containment and heat tests, it said.

    CNNC has four HPR1000 units under construction around the world, which make up the world's only third-generation pressurized water reactor nuclear power project constructed according to schedule.

    Analysts said the successful installation of the outer containment dome will speed up nuclear cooperation between China and countries and regions participating in the Belt and Road Initiative, boosting confidence in China's Hualong One technology.

    Construction of Karachi unit 2 started in 2015 and is scheduled for commercial operation in 2020, said the company.

    According to CNNC, the HPR1000 (Hualong One), the country's self-developed third-generation nuclear power technology, adopts a double containment design, with the outer containment providing protection for the primary containment.

    The outer containment dome is a 366-ton multi-surface shell made up of 63 prescribed components.

    Karachi Nuclear Power Plant (KANUPP) Expansion

    Pakistan’s first nuclear plant Karachi is undergoing a 2,200MW capacity extension with two 1,100 MW pressurised water reactor (PWR) units of Chinese design under construction at the site.

    $10 billion project is being built with financial assistance from China, the biggest energy and infrastructure investor in Pakistan.

    Karachi nuclear power plant is located on the Arabian Sea coast, approximately 18km east of Karachi and has been in service with a single 137MW reactor unit (Kanupp-1) since 1972. It is owned and operated by Pakistan Atomic Energy Commission (PAEC).

    Construction of the Kanupp-2 and Kanupp-3 reactor units started in August 2015 and May 2016, with the start of commercial operations scheduled for 2021 and 2022 respectively.

    Reactor units will have a design life of 60 years and account for approximately 10% of the country’s total generation capacity.

    Cold testing completed at Pakistan's Karachi 2

    China National Nuclear Corporation (CNNC) has completed cold functional testing at unit 2 of the Karachi nuclear power plant (Kanupp) in Pakistan.

    The two units (2&3) under construction at Kanupp are the first exports of China’s Hualong One reactor design.

    Cold functional testing at Karachi 2&3 involved checking some 7200 welds and 800 mechanical connection points within the test boundary for leaks on seven pressure platforms, CNNC said. All indicators met the acceptance criteria, and installation quality and performance meet design requirements.

    Completion of the cold test on 2 December was overseen by the Pakistan Nuclear Regulatory Authority and the Pakistan Atomic Energy Commission. It marks the completion of the main work of the nuclear island installation and the start of the system commissioning stage, CNNC said.

    Hot testing will follow, then first fuel loading and finally grid-connected power generation.

    Construction of Karachi 2 began in 2015 and unit 3 in 2016 for commercial operation in 2021 and 2022. Currently, four Hualong One units are being built in China - two at Fuqing NPP in Fujian province, and two at Fangchenggang NPP in Guangxi – all scheduled for commercial operation in 2019-2020.

    Getting nuclear-ready

    The key message of the “International Conference on Climate Change and the Role of Nuclear Power” held during October 7-11 in Vienna was for major nuclear role as nuclear energy. An integral part of the world’s clean energy future, nuclear power will help fight climate change as it has been a consistent source of low carbon electricity for decades.

    From this perspective, it is a landmark development that another two nuclear power plants of over two-thousand megawatt total capacity would come on stream in Karachi within a couple of years. This will result in enhancing three times the present nuclear energy capacity, achieving around eleven percent share in power generation using various energy resources. With this accomplishment, the policy goals of the government to optimise energy mix and low carbon development would be adequately met, which would also be in line with the international agenda for power sector.

    The government aims at mitigating carbon dioxide emissions up to 20 percent by 2030. By then the installed capacity of nuclear power generation will reach the mark of 8,800MW, as planned, to generate 27,850GWh annually. Pakistan’s total power generation capacity in 2030 is projected to be 46,683MW and envisaged to generate 191,781GWh, according to the SAARC Energy Outlook 2030. The government’s recent plan for capacity addition of about 17,000MW by 2025 is unrealistic, and likely to be achieved by 2030.

    National Electric Power Regulatory Authority (NEPRA) has admitted this month application of the Pakistan Atomic Energy Commission (PAEC) for considering grant of a generation license for its Karachi Nuclear Power Plant-2 (KANUPP-2). The enriched uranium based nuclear power facility of 1,145MW gross and 1,059MW net capacity, is currently in advanced stage of construction, and expected to be connected to national grid sometime during July-November 2020.

    KANUPP-2 is one of the two under-construction units of the Karachi Coastal Power Project of the same type and capacity being supplied by China on turn-key basis. Groundbreaking of the two units was held in November 2013, but construction was held up as the public environmental issues took the matter to the court. Project was re-launched after a gap of about two years. Construction of KANUPP-2 thus commenced in August 2015 and that of KANUPP-3 in May 2016. The second unit, known as KANUPP-3, is scheduled to achieve commercial operations by the end of year 2021. These units will have a design life of sixty years.

    Both the units are subject to safeguards by the International Atomic Energy Agency (IAEA) and the Pakistan Nuclear Regulatory Authority (PNRA). These are pressurised light water reactors (PWR) of advanced design, known as Hualong One or HPR 1000 (HPR stands for Hualong Pressurized Reactor). The reactors have special features of having a single stack layout, 177 nuclear fuel assemblies, a double containment structure, and a combination of active and passive safety systems. The reactors are designed to provide emergency cooling for 72 hours in the absence of electric supply. Instrumentation and control systems are supplied from the European sources.

    Total cost of the two units is estimated as $9.116 billion, which is being financed through a loan from Export-Import Bank of China, on the Chinese side and, on Pakistani side, under the Public Sector Development Program (PSDP) of the government. National Transmission and Despatch Company (NTDC) is constructing additional 16km transmission line for evacuation of power from KANUPP-2 and KANUPP-3. Electricity transmission infrastructure for the project consists of 220KV and 500KV transmission lines, which will be completed in 2021. Generation cost works out Rs9.59 per kWh levelised, whereas plant availability factor is 90 percent.

    Currently, there are five operating nuclear power plants with a cumulative generation capacity of 1,430MW contributing about 4 percent to total generation capacity from all resources of energy. These units provide economical and safe operation. The first nuclear power plant KANUPP-1, currently of 98MW de-rated capacity, was constructed in 1966 with the Canadian assistance and made operational in 1972. It has completed 47 years of safe and successful operation—much beyond its 30-year design life.

    This has been possible through implementing a comprehensive balancing, modernization and rehabilitation plan for the original 137MW nuclear power plant, with technical support from the IAEA. Subsequently, conventional equipment was upgraded and critical equipment and controls were replaced at KANUPP-1. The plant, which is using the fuel produced by the PAEC, is now expected to be shut-down and decommissioned next year.

    It was almost after three decades that the construction of the second nuclear power plant was started at Chashma, in 1993. Now four units of the installed Chashma Nuclear Power Plants (CHASNUPPs) are operational that have 40-year design life. CHASNUPP power plants are considered among the best operating power units in terms of endurance and availability. Average cost of nuclear power to the NTDC is Rs6.35 per unit. Expansion of nuclear power capacity has long been a corner-stone of the national energy policy. CHASNUPP-5 of over 1,000MW capacity is planned for launching in near future. Technological and engineering infrastructure created domestically over the years is supporting the existing, under-construction and planned nuclear power projects.

    Nuclear power is very expensive to install but very cheap once installed...
    This is one of the myth that it is expensive and it is doubly cheap for us because we mine our own uranium...
    It is cleanest, cheapest and a source that produce almost infinite energy from very little raw materials . And it is the cleanest of all .

    true, uranium is cheaper source of power outside large scale hydro and large scale solar...
    this wasnt true in 2015..when solar was expensive than nuclear

    remeber the upfront cost of 2 nuclear plants is 9 billion dollars and will produce 10 billion units/year
    dasu will have cost of 6 b and will produce 18 billion units/year

    and no one has thought of the decommissioning part

    what do you think will happen to the spent fuel for all those reactors ?
