A reliable pressurized water target for F-18 production at high beam currents

Stability evaluation of (18)F-FDG at high radioactive concentrations.

UNLABELLED The objective of our study was to determine the concentration of ethanol, a known radiolytic stabilizer, needed to maintain stability for 12 h at an (18)F-FDG concentration of 19.7-22.6 GBq/mL (533-610 mCi/mL) at the end of synthesis (EOS). METHODS (18)F(-) was formed by the (18)O(p, n)(18)F reaction using 16.5-MeV protons on a cyclotron. (18)F-FDG was synthesized using a synthesis...

Production of [18F] fluoride with a high-current two layer spherical gold target

Background: Fluoride-18 is the most widely used radioisotope for Positron Emission Tomography (PET). [18F] 2-flouro- 2-deoxy D-glucose (FDG) has become a standard tool in the area of clinical research. The oxygen-18 enriched water is the most widely used target for the production of fluoride-18. The use of the nuclear reaction 18O (p,n)18F has been found as the most effective method for the pro...

Corrosion Properties of F82H in Flowing High Temperature Pressurized Water

This work reports the effects of water flow and dissolved oxygen (DO) on corrosion behavior of reduced activation ferritic/martensitic steel, F82H. The corrosion tests were performed in high temperature pressurized water by using a test apparatus for rotated disk sample. All of specimens showed weight gains after static corrosion tests up to 500 h. However, the rotated disk showed weight losses...

Core Loading Design for Bushehr Pressurized Water Reactor

The modified out-in fuel management strategy was applied to the core loading design for the first four cycles of the Bushehr (Iran-1) KWU designed Pressurized Water Reactor (PWR). The minimum peak-to-average power density was chosen as the objective function of the optimization process. Lattice homogenization and group constants generation were performed by using the LEOPARD computer code. For ...
