A number of radiogenically produced dysprosium isotopes have been studied by in-source laser spectroscopy at ISOLDE using the Resonance Ionization Laser Ion Source (RILIS). Isotope shifts were measured relative to $$^{152}$$Dy in the $$4f^{10}6s^{2}~^{5}I_{8}$$ (gs) $$rightarrow$$ $$4f^{10}6s6p~(8,1)^{0}_{8}$$ (418.8 nm $$_{rm VAC}$$)resonance transition. The electronic factor, $$F$$, and mass shift factor, M, were extracted and used for determining the changes in mean-squared charge radii for $$^{rm 145m}$$Dy and $$^{rm 147m}$$Dy for the first time.

The $$alpha$$-decay branching ratio of 0.52(5)% from the ground state of $$^{180}$$Pt to the ground state of the daughter nucleus $$^{176}$$Os has been determined more precisely than before. The $$^{180}$$Pt was produced as the $$beta$$-decay granddaughter of $$^{180}$$Hg which was produced and separated with the CERN-ISOLDE facility. The reduced $$alpha$$-decay width calculated with the present result has provided a new picture of the systematics for the $$alpha$$-decay width of neutron-deficient Pt isotopes.

The electron cyclotron (EC), ion cyclotron (IC), neutral beam (NB) and, lower hybrid (LH) systems for ITER have been reviewed in 2007/2008 in light of progress of physics and technology. Although the overall specifications are unchanged, notable changes have been approved. Firstly, the full 73MW should be commissioned and available on a routine basis before the D/T phase. Secondly, the possibility to operate the NB at full power during the hydrogen phase requiring new shine through protection; IC with 2 antennas with increased robustness; 2 MW transmission systems to provide an easier upgrading of the EC power; the addition of a building dedicated to the RF power sources and to a testing facility for acceptance of diagnostics and heating port plugs. Thirdly, the need of a plan for developing, in time for the active phase, a CD system such as LH suitable for very long pulse operation of ITER was recognized.

Port Limiter is one of important components of ITER (International Thermonuclear Experimental Reactor) with sophisticated geometry. A particular and accurate MCNP input model of ITER with Port Limiter for nuclear analysis was generated with MCAM (Monte Carlo particle Transport Calculated Automatic Modeling System). This paper introduces the detailed work flow of preprocessing of CAD engineering model and validates the MCNP model generated before the actual calculation. The successful application demonstrates that MCAM is capable of dramatically increasing the efficiency and accuracy to generate MC (Monte Carlo) models from CAD engineering models with complex geometry comparing with the traditional manual modeling method.
