“…Due to the large number of diagnostics systems required for the commissioning and operation of ITER it is imperative that the interfaces to CODAC, central interlock system and central safety system are well defined and standardized [8]. This is especially important since the diagnostics systems are provided as in-kind contribution from all 7 domestics agencies.…”

“…Nuclear heating values are 2 MW/m 3 applied for the outer box and 1 MW/m 3 applied for the inner box and mirrors [5]. Radiative plasma heating values are from maximum 150 kW/m 2 applied on the plasma facing area of the outer box to minimum 50 kW/m 2 applied on the lower area of the outer box and the reflecting surface of the 1st mirrors [6]. Heat transfer coefficient which depends on cooling path diameter is applied on cooling path area as a boundary condition for cooling.…”

The Divertor Impurity Monitor (DIM) for ITER is a spectroscopic diagnostic that measures the parameters of impurities and isotopes of hydrogen in the divertor plasmas. The DIM systems are installed in upper port, equatorial port, lower port (LP) and the divertor cassette. The LP systems consist of the side-upper/lower optical systems and the central optical system. In the central system, the front-end optics (optical mirrors) are located under the divertor-dome and this optics is required to have a structure that can withstand extremely high thermal loads in terms of establishing a sensitive optical structure. This paper presents a mechanical design of the optics with taking manufacturability into account and structural integrity assessment according to ITER load conditions (thermal and electromagnetic loads, etc.) and design criteria specified in the RCC-MR code. The mechanical design of the optics forms a box-shaped optics and the structural analysis results indicate the mirror box satisfies design criteria in the RCC-MR code, except for the inner support part interfacing with the divertor cassette.

“…The inner diameter of the cooling path and water flow rate in plasma facing parts were 10 mm diameter and 10 l/min, and those in others were 8 mm diameter and 3 l/min. The thermal load conditions for nuclear heating and radiation heat flux in the divertor area were referred [7,8]. The nuclear heating is 2 MW/m 3 to 1 MW/m 3 .…”

ITER diagnostic lower ports will be used to exchange divertor cassettes and install diagnostic systems. Invessel components of diagnostic lower port #02 (LP#02) will be mounted on a divertor cassette and a support structure, so-called a diagnostic rack, to be removed and reinstalled collectively. Japan Domestic Agency is responsible for procurements of an integration engineering of LP#02 and a divertor impurity monitor, a main tenant system in LP#02. This paper presents preliminary thermal analyses for two critical components in LP#02, the diagnostic rack and a mirror box on the divertor cassette, which will be exposed to the harsh thermal load from plasma. Realistic fabrication methods for cooling the diagnostic rack and a required cooling path layout of the mirror box on the divertor cassette have been assessed to implement the preliminary design from the viewpoint of thermal analysis.
