Improvement of the MELCOR condensation heat transfer model for the thermal-hydraulic analysis of a PWR containment

Thermal Energy Processes in Direct Steam Generation Solar Systems: Boiling, Condensation and Energy Storage – A Review

“…Much research has been conducted on improvement to the efficiency of power plants. This has led to proposals for new configurations and cycle architectures (Wu et al, 2012;Zhang and Zhang, 2013;Mcgrail et al, 2017), suggestions for improving the efficiency of the two-phase phenomena in power plants, such as boiling (Nie et al, 2017;Tian et al, 2017;Ahmadpour et al, 2018) and condensation (Yoo et al, 2018), as well as recommendations for improving the overall efficiency of plant through operation in cogeneration mode (Das and M. Al-Abdeli, 2017;Gvozdenaca et al, 2017;Moradi et al, 2017).…”

Interfacial heat transfer with non-condensable gas in ASTEC V2.2: Application to severe accidents study during PWR cold shutdown states

“…Kageyama et al [9] present the calculation method in detail for film condensation in vertical tubes. In the case of system codes, this approach has been used for example for the thermal-hydraulic in the containment modelling with MELCOR [10] or MARS [11]Error! Reference source not found..…”

Improvement of Condensation Model With the Presence of Non-Condensable Gas for Thermal-Hydraulic Analysis in Containment

“…Whether the heat transfer occurring on the surface of the containment wall and the surface of the internal structures can effectively transfer energy to the environment will directly affect the pressure behavior in the containment. Convective heat transfer and condensation heat transfer are two mechanisms to transfer heat out of the containment, and the latter is the key mechanism for heat removal and pressurization mitigation (Yoo et al, 2018). Therefore, it is significant to carry out the evaluation of condensation model to predict pressure behavior of the containment accurately under accident conditions.…”
