This study is prompted by numerous problems in both the maintenance of equipment during reactor operation and the dismantling of the reactor after the completion of the operation, which is associated with contamination of working surfaces with long-lived radionuclides. The composition of the oxide films formed on the surface of commercial titanium alloy \u041fT-3B has been studied with specimens prepared in autoclave test conditions and surface samples from the pipeline sections to which the primary coolant was applied. These films on the coolant pipeline surface consist of a titanium dioxide layer tightly adhered to the pipeline metal surface and weakly fixed deposits\u2014crystallites comprised of titanium oxides and other corrosion products (oxides and hydrated oxides of iron, nickel, chromium etc.). The radionuclide composition of the samples was studied by gamma-spectrometry. It is shown that the mechanism of titanium-surface contamination with 137Cs is by physisorption, contamination level increases upon the presence of dispersed particles. For 60Co, both sorption and deposition onto surfaces are observed.<\/jats:p>","DOI":"10.3390\/ma15124261","type":"journal-article","created":{"date-parts":[[2022,6,17]],"date-time":"2022-06-17T05:25:11Z","timestamp":1655443511000},"page":"4261","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":2,"title":["Sorption of 137Cs and 60Co on Titanium Oxide Films in Light Water Reactor Primary Circuit Environment"],"prefix":"10.3390","volume":"15","author":[{"given":"Nikita A.","family":"Glukhoedov","sequence":"first","affiliation":[{"name":"Institute of Chemistry, Saint-Petersburg State University, 7\/9 Universitetskaya Emb., 199034 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Vitaliy N.","family":"Epimakhov","sequence":"additional","affiliation":[{"name":"Federal State Unitary Enterprise \u201cAlexandrov Research Institute of Technology\u201d, 72, Koporskoe Shosse, 188540 Sosnovy Bor, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sergey N.","family":"Orlov","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Saint-Petersburg State University, 7\/9 Universitetskaya Emb., 199034 St. Petersburg, Russia"},{"name":"Federal State Unitary Enterprise \u201cAlexandrov Research Institute of Technology\u201d, 72, Koporskoe Shosse, 188540 Sosnovy Bor, Russia"},{"name":"Institute of Nuclear Industry, Peter the Great St. Petersburg Polytechnic University (SPbSU), 29, Polytechnischeskaya, 195251 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Anastasiya A.","family":"Tsapko","sequence":"additional","affiliation":[{"name":"Federal State Unitary Enterprise \u201cAlexandrov Research Institute of Technology\u201d, 72, Koporskoe Shosse, 188540 Sosnovy Bor, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Aleksandr A.","family":"Zmitrodan","sequence":"additional","affiliation":[{"name":"Federal State Unitary Enterprise \u201cAlexandrov Research Institute of Technology\u201d, 72, Koporskoe Shosse, 188540 Sosnovy Bor, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Grigoriy A.","family":"Zmitrodan","sequence":"additional","affiliation":[{"name":"Federal State Unitary Enterprise \u201cAlexandrov Research Institute of Technology\u201d, 72, Koporskoe Shosse, 188540 Sosnovy Bor, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9841-150X","authenticated-orcid":false,"given":"Mikhail Yu.","family":"Skripkin","sequence":"additional","affiliation":[{"name":"Institute of Chemistry, Saint-Petersburg State University, 7\/9 Universitetskaya Emb., 199034 St. Petersburg, Russia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,6,16]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"32","DOI":"10.1016\/j.corsci.2019.01.020","article-title":"Oxide formation on titanium alloys in primary water of nuclear pressurised water reactor","volume":"150","author":"Bignon","year":"2019","journal-title":"Corros.
