[72]Bahnhof, which apparently used to host WikiLeaks in one of its datacenters, is understood to be investigating the possibility of installing a small modular reactor (SMR) at a datacenter being built in Hjorthagen, a district of Sweden's capital. According to a report in The Times newspaper, Bahnhof CEO Jon Karlung said the reactor could also provide enough power for 30,000 households in the surrounding area, and could be ready to go online within just a couple of years if given the go-ahead. Karlung told local TV news [73]SVT Nyheter that it might be considered "provocative" to want to build a nuclear power station in Stockholm, but claimed there are advantages to building small power plants where required. Datacenters in Sweden currently consume 3 terawatt hours (TWh) a year, according to SVT Nyheter, and this is estimated to double to 6TWh within just a couple of years. It isn't just Sweden where this approach is being considered. In the US, the Nuclear Regulatory Commission (NRC) has recently [74]finalized rules allowing construction of nuclear small modular reactors (SMRs), although not specifically for powering datacenters. The Register last year reported that engineering company Rolls-Royce was [75]on the lookout for sites in the UK to deploy SMRs, as well as a location for a factory to build the new reactors. * [76]Uncle Sam greenlights first commercial nuclear small modular reactor design * [77]Nuclear-powered datacenter throws open doors to tenants this year * [78]Miniature nuclear reactors could be the answer to sustainable datacenter growth * [79]US regulators set the stage for small, local nuclear power stations The UK government previously announced an [80]Advanced Nuclear Fund of up to £385 million as part of its 10-point plan for a green industrial revolution, up to £215 million of which is for SMRs, to develop domestic small-scale power plant technology. A report published by analyst Omdia at the end of last year made the case for [81]using SMRs to power datacenters. It suggested the sweet spot for SMRs will likely be for facilities exceeding 100MW in capacity, although smaller datacenters could partner with local utilities and other power-hungry industrial sites to make it a viable option - as Bahnhof appears to be proposing. SMRs are considerably smaller in scale than the large nuclear plants most people are familiar with, Omdia claimed, and pose far less risk. However, the biggest challenge in getting these up and running will be "convincing people in industry and where these things are going to [be deployed], that it is safe, and viable, and environmentally friendly," one of the report authors commented. There could also be downsides to this kind of technology. Another report published last year suggested that mini nuclear reactors such as SMRs might generate [82]up to 35 times more waste to produce the same amount of power as a traditional nuclear plant. ® Get our [83]Tech Resources (BUTTON) Share Similar topics * [84]Datacenter * [85]Nuclear Power * [86]Sweden More like these × Similar topics * [87]Datacenter * [88]Nuclear Power * [89]Sweden Narrower topics * [90]Disaster recovery * [91]ESA * [92]Fusion Power * [93]Open Compute Project * [94]PUE * [95]Software defined data center Broader topics * [96]Electricity * [97]EMEA * [98]Europe * [99]European Union * [100]Nordic Countries Similar topics (BUTTON) Share [101]3 comment bubble on white COMMENTS Similar topics * [102]Datacenter * [103]Nuclear Power * [104]Sweden More like these × Similar topics * [105]Datacenter * [106]Nuclear Power * [107]Sweden Narrower topics * [108]Disaster recovery * [109]ESA * [110]Fusion Power * [111]Open Compute Project * [112]PUE * [113]Software defined data center Broader topics * [114]Electricity * [115]EMEA * [116]Europe * [117]European Union * [118]Nordic Countries TIP US OFF [119]Send us news __________________________________________________________________ Other stories you might like Datacenters in China, Singapore cracked by crims who then targeted tenants Infiltrators tried to create fake remote hands tasks, alter visitor lists Cyber-crime23 Feb 2023 | Datacenters still a boys' club, staffing shortages may change that Fifth of server warehouse operators polled didn't employ a single female worker On-Prem2 Mar 2023 | 37 Microsoft wants to export 'grid-interactive' Dublin datacenter setup It's all about being 'aware' of effect power consumption has on energy networks On-Prem24 Feb 2023 | 7 Cloud infrastructure spreads its wings How Huawei KooVerse brings low latency IaaS to customers everywhere Sponsored Feature Lonestar bags $5m in seed funding for lunar datacenter project That's one small step for upstart, with many, many more to go On-Prem7 Mar 2023 | 4 Euro bit barn biz has hot prospect: immersion cooling for colo customers Aims at those who need help with green targets ... months after Intel axes R&D into tech On-Prem20 Feb 2023 | 7 Unless things change, first zettaflop systems will need nuclear power, AMD's Su says Of course the company that figured out chiplets says the answer is more chiplets Systems23 Feb 2023 | 54 Oracle NetSuite datacenter plunges offline for a day, customers warned of data loss Updated Anything could happen in a half hour Off-Prem15 Feb 2023 | 10 AWS puts datacenter in shipping container for the Pentagon Ditch the special forces helicopter - it's easier to ship it in an actual ship On-Prem15 Feb 2023 | 15 5% of the cloud now runs on Arm as chip designer plans 2023 IPO Growing indication power-sipping CPUs are catching on in crowded datacenters Systems8 Feb 2023 | 9 Nuclear-powered datacenter throws open doors to tenants this year Hit up Cumulus Data if you want your racks running on low-cost, zero-carbon energy On-Prem19 Jan 2023 | 20 Power grid worries force Amazon to run Oregon datacenters using fuel cells And not the green hydrogen kind Systems6 Feb 2023 | 9 The Register icon Biting the hand that feeds IT About Us * [120]Contact us * [121]Advertise with us * [122]Who we are Our Websites * [123]The Next Platform * [124]DevClass * [125]Blocks and Files Your Privacy * [126]Cookies Policy * [127]Privacy Policy * [128]T's & C's * [129]Do not sell my personal information [130]Situation Publishing Copyright.
