• Note (General): 高速増殖炉の蒸気発生器における大リーク・ナトリウム-水反応時の諸現象を解析するため、大リーク・ナトリウム-水反応解析コードSWACSが開発された。これまでSWACSコードに含まれている準定常圧計算モジュール(SWAC-13)を検証するために、蒸気発生器安全性総合試験装置(SWAT-3)による大リーク・ナトリウム-水反応試験(Run-3$\sim$-6試験: 水リーク率約8$\sim$15kg/s)を基に解析が行われた。実験検証では、同計算モジュールによる。; SWACS code has been developed to estimate the sodium-water reaction phenomena in FBR steam generator (SG) over the range of large water leak. Sensitivity analysis was carried out to verify quasi-steady pressure calculation module SWAC-13 in SWACS on the basis of tube damage propagation test data of Steam Generator Safety Facility (SWAT-3 Runs through 3 to 6; water leak rates are about 8-15kg/s) until now. It was confirmed that reference condition A (REF-A), reference condition B (REF-B) and important parameter in calculation such as hydrogen gas/water mole conversion ratio (f) and hydrogen temperature (THG) used in SWAC-13 were effective. REF-A provides good agreement with test results and REF-B provides conservative results for safety evaluation. In this report validation analysis was performed in which SWAC-13 was applicable to intermediate water leak in calculation condition based on SWAT-3 Run-13 (Water leak rate is about 0.9kg/s) data with the same condition of above-mentioned large leak region. The following results were obtained. 1. REF-A is f (=0.5), THG (= the maximum temperature of experiment measurement) and slip ratio (2.0 at RV and relief line, 1.0 at secondary loop), this condition REF-A provides good agreement generally. 2.REF-B is f (=0.65), THG(= 727degree at all region ) and slip ratio (=1.0), This condition REF-B provides conservative results for safety evaluation. 3.In the sensitivity analysis of f, for the maximum pressure of experiment measurement which made f =0.5 to be a standard increases than f =0.65 at about 10\%, and it decreases than f =0.35 at about 10\%. 4.Pressure calculation result by the sensitivity analysis of THG increases at the order of initial sodium temperature , the maximum temperature of experiment measurement and 727degree at all region.
