The calculations are based on HART's tensile test equation and on a phenomenological cavitation damage model. From this model the life fraction rule (LFR) is derived. Analytical expressions for the lifetimes are derived, which contain only stationary stress rupture data. The creep behavior of non-cavitating and ideally plastic materials is derived from the solution of the tensile test equation for the particular loading conditions considered. Cavitation damage is known to influence the creep behavior by reducing the load bearing capability.

Remote maintenance techniques or special treatment may be required to limit the amount of radiation exposure to plant operational and maintenance personnel. A computer code, RAPTOR, has been developed to estimate the transport of this activated material throughout a fusion heat transfer and/or tritium breeding material loop. A method is devised which treats the components of the loop individually and determines the source rates, deposition and erosion rates, decay rates, and purification rates of these radioactive materials. RAPTOR has been applied to the MARS and Starfire conceptual reactor designs to determine the degree of the possible radiation hazard due to these products. Due to the very high corrosion release rate by HT-9 when exposed to LiPb in the MARS reactor design, the radiation fields surrounding the primary system will preclude direct contact maintenance even after shutdown. Even the removal of the radioactive LiPb from the system will not decrease the radiation fields to reasonable levels. The Starfire primary system will exhibit radiation fields similar to those found in present pressurized water reactors.</p></div>","PeriodicalId":82205,"journal":{"name":"Nuclear engineering and design/fusion : an international journal devoted to the thermal, mechanical, materials, structural, and design problems of fusion energy","volume":"2 3","pages":"Pages 355-363"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0167-899X(85)90023-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73675478","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}

This test section is a beam-driven simple mirror, where 11 MW of fusion power produces a neutron flux of ∼ 2 MW/m<sup>2</sup>. In this test section one can perform 100 h uninterrupted tests of the power and fuel cycle operation of fusion blankets. The tandem mirror in which this section is embedded is a scale down version of the MARS reactor. It uses 200 kV negative ion beams, an 18 T choke coil, drift pumping for removing α-ash and ions trapped in the barrier/transition, halo pumping, and biased end plates for potential control and direct conversion. There are two modes of operation in the device: one mode achieves the high neutron flux by injecting beams in the test section and reducing the end plug potential to accommodate the high throughput of particles; the other mode reduces the beam input to the minimum required for fueling and raises the end potentials to their highest possible values for good confinement. This two-mode operation is a unique feature of the tandem that allows a dual physics-nuclear technology role for the device.</p></div>","PeriodicalId":82205,"journal":{"name":"Nuclear engineering and design/fusion : an international journal devoted to the thermal, mechanical, materials, structural, and design problems of fusion energy","volume":"2 2","pages":"Pages 209-222"},"PeriodicalIF":0.0,"publicationDate":"1985-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0167-899X(85)90013-8","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91773265","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}
