Reactor vessel cladding separate effects studies

Reactor Pressure Vessel Embrittlement—i

Two separate thoroscopic segmentectomies with vessel sealing system.

Total thoracoscopic segmentectomy is an appealing concept in terms of providing a parenchyma-sparing treatment. We describe our technique of two seperate total thoracoscopic segmentectomies by using a vessel sealing system (VSS). A 76-year old female with four gradually enlarging ground glass lesions on the right segment 2 (10 and 3 mm) and segment 6 (8 and 3 mm) was admitted to our institute f...

Specific effects in microwave chemistry explored through reactor vessel design, theory, and spectroscopy.

Microwave chemistry has revolutionized synthetic methodology for the preparation of organics, pharmaceuticals, materials, and peptides. The enhanced reaction rates commonly observed in a microwave have led to wide speculation about the function of molecular microwave absorption and whether the absorption leads to microwave specific effects and enhanced molecular heating. The comparison of theor...

Aging and Life Management System of Reactor Pressure Vessel

Reactor pressure vessel (RPV), the only key component that can not be replaced in nuclear power plants (NPPs), is the main barrier against the radioactive leakage. The lifetime of NPPs is dependent heavily on the life of RPV, and thus, the aging and life research on a RPV is a key factor in determining the life extension of NPPs. The purpose of this paper is to introduce an aging and life manag...

Positron Annihilation Measurements on Nuclear Reactor Pressure Vessel Steels

Positron Annihilation Spectroscopy is a valuable microscopic method to study radiation damage in nuclear reactor pressure vessel steels. At SCKoCEN, a new positron lifetime setup, suited to measure positron lifetimes in irradiated steel, is being constructed. The particularity of this setup is that the prompt count rate originating from the induced 60Co-activity in the steel is highly reduced. ...
