Determination of tritium production in the liquid blanket of fusion reactor is necessary for the nuclear material accounting system. In this paper, an equivalent measurement method is proposed, which is based on measuring the isotope abundance of lithium before and after irradiation. Theoretical analysis of the feasibility of the method is carried out, including complex nuclear reactions of neutron and lithium, the influence of the lead matrix, and the influence of gradient of the lithium isotope abundance before and after irradiation.

The corrosion behavior of stressed C-rings made of martensitic steel T91 was investigated through constant strain tests. The specimens with different initial hoop stresses (0 MPa, 150 MPa and 300 MPa) were exposed to static oxygen saturated lead–bismuth eutectic (LBE) at 480 °C for 500 h, 1000 h and 1500 h, respectively. The results showed that no crack was found on the outer surface of all the specimens after exposure; and the microscopic analysis showed that the specimens were covered with two oxide layers, which included a magnetite outer layer and a Fe–Cr spinel inner layer. The transformation of spinel into magnetite at the spinel/magnetite interface might be promoted by stress, which increased the difference between the thickness of the inner and outer layers. Moreover, the steel loss was estimated by the observed oxide layers; it increased rapidly when the stress was above 300 MPa, and was about 1.3 times of when the stress was absent.

ARIMA model is widely-range used in forecasting analysis area. The paper establishes an ARIMA model on the employment information of computer industry from 2002 to 2007 in China, and using the model, gives a prediction of situation in 2008. The study will be an exploration for subsequent researches on employment situation forecasting, or other related work.
