The primary source of time correlated passive neutrons is the spontaneous fission of Pu, where the <sup>240</sup>Pu is usually the dominant isotope with <sup>238</sup>Pu and <sup>242</sup>Pu also contributing to a degree depending on the grade or burnup of the material. Consequently, knowledge of the <sup>240</sup>Pu spontaneous fission rate, expressed as fission per gram per second, and the associated uncertainty is key in interpreting measurement data absolutely. The <sup>240</sup>Pu spontaneous fission rate derives (and vice versa) from the <sup>240</sup>Pu spontaneous fission half-life. In this work we review and reevaluate the available experimental data on the spontaneous fission (SF) half-life of the Pu isotopes <sup>238</sup>Pu, <sup>240</sup>Pu and <sup>242</sup>Pu. The SF half-lives are used to compute the corresponding specific SF rates which are the traditional nuclear data parameters needed for analytical applications, especially the nondestructive assay of plutonium for safety, security and safeguards.</p><p>From 7 measurements we recommend a SF half-life of (4.745 ± 0.083) × 10<sup>10</sup> <em>y</em> for <sup>238</sup>Pu corresponding to a specific SF rate of (1171 ± 20) fis ⋅ s<sup>-1</sup> ⋅ g<sup>-1</sup>.</p><p>There are 16 absolute experimental determinations of <sup>240</sup>Pu half-life. Based on this evaluation, we find that the weighted mean of the 16 half-life determinations is (1.1608 ± 0.0091) × 10<sup>11</sup> <em>y</em> corresponding to a specific SF rate of (474.7 ± 3.7) fis ⋅ s<sup>−1</sup> ⋅ g<sup>−1</sup>, where the relative uncertainty of about 0.78% is the external standard error.</p><p>From 8 measurements we recommend a SF half-life of (6.766 ± 0.037) × 10<sup>10</sup> <em>y</em> for <sup>242</sup>Pu corresponding to a specific SF rate of (807.7 ± 4.4) fis ⋅ s<sup>−1</sup> ⋅ g<sup>−1</sup>. Finally, we conclude that there is a need for more experiments on all three plutonium nuclides using new techniques that have emerged in recent years.</p></div>","PeriodicalId":49735,"journal":{"name":"Nuclear Data Sheets","volume":"175 ","pages":"Pages 269-287"},"PeriodicalIF":3.7,"publicationDate":"2021-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/j.nds.2021.06.003","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42498635","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
