Starting actual final disposal activities requires an operating licence for the facility from the government. Used nuclear fuel will be placed in the bedrock, at a depth of about 450 metres. The disposal system consists of a tightly sealed iron-copper canister, a bentonite buffer enclosing the canister, a tunnel backfilling material made of swellable clay, the seal structures of the tunnels and premises, and the enclosing rock.<\/p>\n<p>Posiva&#8217;s plan is for used fuel to be packed inside copper-steel canisters at an above-ground encapsulation plant, construction of which began in September 2019 and is scheduled to be completed in mid-2022. Posiva noted the encapsulation of used nuclear fuel and the emplacement of the canisters in the deposition holes will start once the Finnish government grants the operating licence for the final disposal facility. &#8221;The current estimate is that the final disposal operation will start in the mid-2020s,&#8221; said Kimmo Kemppainen, Posiva&#8217;s programme manager. &#8221;The excavation and reinforcement of the tunnels, which have now been started according to tight regulatory requirements, signify for Posiva a transfer to the execution of the most complex and exacting rock structure system in Onkalo.&#8221;<\/p>\n<p>In March this year, Posiva announced that work to excavate a tunnel had started at the Onkalo for the &#8217;joint functional test&#8217;, which involves small-scale final disposal under actual conditions, and is part of commissioning the geological repository. That tunnel will be about 80m long and four deposition holes will be drilled into it during the joint functional test, which will take place in 2023. This test will demonstrate that the processes and procedures related to final disposal are in order and, only then, can the disposal facility be granted an operating licence.<\/p>\n<p>Source: <a href=\"https:\/\/waste-management-world.com\/a\/finnish-posiva-is-the-first-company-in-the-world-to-implement-geological-final-disposal\">Waste Management World<\/a><\/p>\n<p>&nbsp;<\/p>\n<p>&nbsp;<\/p>\n<\/div>","protected":false},"excerpt":{"rendered":"<p>The project, with a total value of some 500 million euro, consists of Posiva building and furnishing all the facilities required for final disposal activities,&#8230;<\/p>","protected":false},"author":4,"featured_media":13005,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_FSMCFIC_featured_image_caption":"","_FSMCFIC_featured_image_nocaption":null,"_FSMCFIC_featured_image_hide":null,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false},"categories":[5594],"tags":[13121,201,745,13120],"class_list":["post-48329","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-chief-editors-choice","tag-final-disposal","tag-finland","tag-nuclear-waste","tag-posiva","wpcat-5594-id"],"jetpack_featured_media_url":"https:\/\/i0.wp.com\/vastuullisuusuutiset.fi\/wp-content\/uploads\/2020\/06\/radioactive-2056863_1920.jpg?fit=100%2C100&ssl=1","jetpack_sharing_enabled":true,"_links":{"self":[{"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/posts\/48329","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/users\/4"}],"replies":[{"embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/comments?post=48329"}],"version-history":[{"count":1,"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/posts\/48329\/revisions"}],"predecessor-version":[{"id":48330,"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/posts\/48329\/revisions\/48330"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/media\/13005"}],"wp:attachment":[{"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/media?parent=48329"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/categories?post=48329"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/vastuullisuusuutiset.fi\/en\/wp-json\/wp\/v2\/tags?post=48329"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
