An old issue and a new challenge for nuclear reactor safety

F. D’AURIA

Frontiers in Energy 2021, Volume 15, Issue 4,   Pages 854-859 doi: 10.1007/s11708-021-0729-0

Abstract: Nuclear reactor safety (NRS) and the branch accident analysis (AA) constitute proven technologies: theseLarge break loss of coolant accident (LBLOCA) has been, so far, the orienting scenario within AA andElectronic and informatics systems were in extensive use and their impact in case of accident becomesmore and more un-checked (however, quite irrelevant in case of LBLOCA).The present paper deals with the LBLOCA that is inserted into the above context.

Experimental study of critical flow of water at supercritical pressure

Yuzhou CHEN, Chunsheng YANG, Shuming ZHANG, Minfu ZHAO, Kaiwen DU, Xu CHENG

Frontiers in Energy 2009, Volume 3, Issue 2,   Pages 175-180 doi: 10.1007/s11708-009-0029-6

Abstract: Experimental studies of the critical flow of water were conducted under steady-state conditions with a nozzle 1.41 mm in diameter and 4.35 mm in length, covering the inlet pressure range of 22.1-26.8 MPa and inlet temperature range of 38-474°C. The parametric trend of the flow rate was investigated, and the experimental data were compared with the predictions of the homogeneous equilibrium model, the Bernoulli correlation, and the models used in the reactor safety analysis code RELAP5/MOD3.3. It is concluded that in the near or beyond pseudo-critical region, thermal-dynamic equilibrium is dominant, and at a lower temperature, choking does not occur. The onset of the choking condition is not predicted reasonably by the RELAP5 code.
