We also expect that J-PARC can operate for 50 weeks over one year, and that the parasitic beam time for 10 hours of irradiation will be scheduled three times a week.
Any chemical handling of [sup.99]Mo-[sup.99m]Tc isotopes at the production target has to be done under an extremely high radiation level with minimum disturbance to the main J-PARC activities.
Through the series of RCNP experiments discussed above concerning the feasibility study of the [sup.99]Mo-[sup.96m]Tc production by the J-PARC injector beam, we were able to show that sufficient amounts of [sup.99]Mo isotopes could be produced to cover the total Japanese consumption.
We established a Japanese style solution using the world top-level high-power accelerator facility, J-PARC. Through the feasibility study using the 400 MeV proton beam from the RCNP/RING-cyclotron, it has been shown that a sufficient amount of [sup.99]Mo can be produced at the J-PARC TEF-T beam line.
For instance, after we achieved full confidence about [sup.99]Mo-[sup.99m]Tc production using the J-PARC, a serious question has arisen.
[sup.99]Mo isotope production at the J-PARC (Scenario (1)).
The construction of Japan's largest proton accelerator has been initiated within J-PARC (Japan Proton Accelerator Research Complex) at the coasts of Tokaimura, about 100 km from Tokyo.
This approach was also followed to predict the hydraulic conductivity of soils at J-PARC.
Summing up, the present work presents the results obtained from nine exploratory boreholes within J-PARC, evaluating the sedimentary sequence and investigating the main properties of the soils to effectively characterize the hydrogeology of the site.
The J-PARC complex is located at the Tokaimura, Ibaraki prefecture, which is approximately 100 km northeast of Tokyo.
A plot for the entire data set shows that hydraulic conductivity in J-PARC is close to this distribution (fig.
Drill cores from 9 wells were analyzed to a depth of 200 m at the coastal area of J-PARC, and the main lithological facies and hydraulic properties of the sedimentary sequence determined.
