The saturated solubility of NaI in sodium was measured to be used for the safety analysis of the Fast Breeder Reactors. A saturated preparation vessel, and test apparatus was designed and preparation procedures for the study was established. The test was conducted in the sodium temperature range of 500$$^{circ}$$C-800$$^{circ}$$C. From the resu1ts obtained the two empirical equations saturated solubility have been derived: [log$$_{10}$$S$$_{H}$$ = 8.557-3524/T(800$$^{circ}$$C-661.4$$^{circ}$$C)] [log$$_{10}$$S$$_{L}$$ = 9.751-4640/T(661.4$$^{circ}$$C-500$$^{circ}$$C)] [S$$_{H}$$, S$$_{L}$$ : saturated solubility (ppm)] [T : absolute temperature (K)] The above two equations of the saturated solubility represented test result with 1% errors. An intersection of the equations completely agreed with the melting point 661.4$$^{circ}$$C of NaI. The results with the present ones by M, A, Bredig et al. agrees.

Instrumented test assembly (INTA) had been installed in experimental fast reactor JOYO from MK-Ii 8th duty cycle to the special testing cycle after 12th duty cycle. New information on core characteristics are obtained by noise analysis of various in-core sensors installed in INTA. (Flux monitor, thermocouples which measure fuel center and coolant temperature, et al.) They are not able to be obtained by conventional instrumentation. Main results are as follows. (1)Peak, existed in frequency band where space dependent characteristics is found, observed by ex-core flux monitor (about 4$$times$$10$$^{-2}$$Hz) is induced by some phenomena outside fuel zone. (2)Transfer function between neutron flux and fuel center temperature successfully corresponds to analysis results which assumes time constant of fuel center temperature sensor is about 2 seconds. (3)Deterioration of fuel center temperature sensor can be detected or predicted by monitoring of its noise characteristics. (4)Time constant of thermal expansion of core support plate is estimated to be about 8 seconds.
