The primary purpose of the fission chambers is to provide an absolute calibration of the neutron rate, while the scintillator detectors monitor fast excursion in the neutron yield due for instance, to fast MHD events. Within the last 10 years NSTX has performed 4 separate calibrations of the neutron monitoring system. Initially, a californium neutron source on a long tether was introduced into the vessel through 10 different top ports on NSTX corresponding to 10 of the 12 bays of the vessel. Each of the ports was at the same major radius just slightly larger than the nominal plasma major radius and a point-wise ring source was simulated to perform the calibration. Recently, the fission chambers were relocated to accommodate new equipment and the detector system required recalibration. This most recent calibration employed a commercial G-gauge model train and three different diameter circular tracks to transport the 252CF neutron source around the midplane of the NSTX vessel. In each of the calibrations, the fission chambers were operated in the pulse counting mode. During plasma operations one of the detectors transitions to the pulse saturated or current mode of operation. To complete the calibration, a series of low performance He discharges heated with one deuterium neutral beam were performed. Neutrons in this case come predominantly from beam-beam reactions. These low-yield discharges produced neutron levels that allowed the FC2 to remain in pulse counting mode while FC1 transitioned into the current mode. This allows a cross calibration to be performed between FC2 in pulse counting mode and FC1 in the current mode. The current mode value is then transferred to each of the four scintillating detectors. The results of the four insitu calibrations are presented.","PeriodicalId":393592,"journal":{"name":"2011 IEEE/NPSS 24th Symposium on Fusion Engineering","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126590386","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}

The main purpose of the feeders is to convey the cryogenic supply and electrical power to the coils as well as house the instrumentation wiring. The Feeder carries superconducting busbars, supercritical cryo-pipes and instrumental pipes from the CTB to the coil. The PF busbar which carries 52kA current will suffer from high Lorentz force due to the background magnetic field inspired by the coils and the self field between every pair of busbars. Peak magnetic force could be 6tons/m in the ICF region that requires dense supports. But to minimize the heat load to the busbars as well as the cryo-pipes, fewer and weaker supports design is proposed, so a balance between mechanical strength and thermal insulation performance should be achieved. This paper presents the simulation and analysis on support system design for ITER 1st PF feeder including the S-Bend Box (SBB), the Cryostat Feed-through (CFT), the In-Cryostat-Feeder (ICF), especially for a pair of busbars and main cooling-pipes firstly. This analysis aims to get real magnetic force load under the worst scenario, an electric-magnetic coupled analysis which includes the busbars and the coils is performed, then the Lorentz force result is imported into the mechanical analysis, applied on the busbars, meanwhile the supports and the containment duct are contained in the finite element model (FEM) to check the full system performance under Lorentz forces, earth gravity and thermal contract at 4.5K. Based on the simulative and analytical results, the quantity and the spaces between supports in the 1st PF feeder have been studied and the detail design optimized.","PeriodicalId":393592,"journal":{"name":"2011 IEEE/NPSS 24th Symposium on Fusion Engineering","volume":"115 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127614471","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}

Design, construction, and assembly of an ultra large scale machine such as ITER require thoroughly well defined plans, strategies, and predictions of potential problems and solutions. It is believed that preceding devices and projects may provide useful references for the several important considerations noted above. The KSTAR (Korea Superconducting Tokamak Advanced Research), a representative superconducting tokamak, has the most similar characteristics to the design concept of the ITER. Therefore, the lessons learned from KSTAR can be categorized according to the following engineering aspects: 1) policies to prioritize decisions, 2) catch-up plans for delayed schedules, 3) strategies in site assembly, 4) troubleshooting, 5) standard indexes or guides for tests and acceptance of individual systems and of site assemblies, and 6) interfaces that can be easily omitted in view of the system integration. This paper will summarize the lessons we have learned from the KSTAR project, focusing on engineering related points that can be considered to suggest guidelines for the ITER construction.","PeriodicalId":393592,"journal":{"name":"2011 IEEE/NPSS 24th Symposium on Fusion Engineering","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2011-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"122621828","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}
