The corrosion of pure UO2 and UK Advanced Gas-cooled Reactor (AGR) simulated spent nuclear fuels (SIMFUELs) was studied under conditions typical of those found in interim spent fuel storage pond waters. With respect to the dissolution of spent fuel, it appears to be advantageous to dose the ponds to pH≈11.4. The alkaline conditions in the pond water suppress the dissolution as UO2 which may otherwise occur at neutrality and lower pHs.","PeriodicalId":20706,"journal":{"name":"Progress in Nuclear Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83076441","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this study, we estimated the quantity of uranium precipitated at the natural barrier using one-dimensional migration analysis, and studied dimension of uranium precipitated in the natural barrier and carried out the criticality analysis. As the result, more than 200 MTU is precipitated at redox front in the natural barrier to reach the criticality.

Recently, TRT attracted attention because a newly-developed commercially available pharmaceutical, Ra-223 chloride (trade name; Xofigo), an alpha particle emitting TRT agent. Despite the conventional TRT agents, such as I-131, Sr-89 and Y-90, are beta emitting phamaceuticals, Ra-223 chloride is a first-ever alpha particle emitting TRT product and shows a strong therapeutic effect in patients with bone metastases from prostate cancer because of its poweful cell killing effect of alpha particle irradiation. In TRT research fields, there are several other promising alpha particle emitting TRT agents, and one of these promising alpha particle emitting TRT agents is Ac-225 labelled PSMA-617 (Prostate Specific Membrane Antigen-617), which is a newly developed TRT agent and showed a suprising therapeutic effect in two metastatic prostate cancer patients in end-stage (case report in J Nucl Med 2016). QST and our department recently developed and reported one promising candidate for TRT, metaAt-211 astato-benzylguanidine (At-211-MABG). At-211-MABG is also an alpha-emitting radiopharmaceutical targeting the treatment of neuroendocrine tumors, such as malignant pheochromocytoma. In this session, we would like to show our recent advance in the research of At-211-MABG. One of our research goals is to develop Japan’s first-ever Japanese-made pharmaceutical products for TRT including Ac-225 labelled TRT agents. In addition, we would like to show our strategies in the future development of preclinical and clinical researches, dosimetric researches, and regulatory science, especially in the field of alpha emitter TRT pharmaceutical products.","PeriodicalId":20706,"journal":{"name":"Progress in Nuclear Science and Technology","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2018-11-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"80070414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
