The computer code for a large leak sodium-water reaction in an LMFBR SG-SWACS-has been developed by PNC. The most important parameter of sodium-water reaction phenomena is the water leak rate from a failed tube. To validate the calculation module of water leak rate, named SWAC-11, the thrust forces caused by fluid discharge from a pipe were measured and compared with the computer code. This report describes a model of the thrust fonce calculation, the measuring method of the thrust force, and comparisons between gas blowdown tests and calculational results by SWAC-11. Major conclusions are as follows : (1)Compared with analytical solutions and experimental data, the numerical calculation method of SWAC-11 was validated. (2)The short term transient of thrust force could be measured using the spring-mass model. (3)Compared with analytical solutions, the "cell center approximation" was found to be good as a thrust force calculation model of SWAC-11. High temperature and water blowdown tests using this measuring method will be described in the No.2 report.

In this study, we developed a new method to visualize and evaluate the movement of 
C-photosynthates into the root system and 11C-rhizodeposits released in the soil coupled with positional information using the positron-emitting tracer imaging system. A newly developed rhizobox was consisted of a square nylon mesh bag containing the root system and a pair of soil boxes, and it could be distinguishing the C signal of soil from that of root. Test plants of white lupin (Lupinus albus) and soybean (Glycine max) were grown in the rhizobox, and fed CO
as a pulse. Simultaneously, the behavior of 11C-photosynthates into the root system and the distribution of C-rhizodeposits released in the rhizosphere soil were visualized.
