The transient behaviors of natural circulation loop (NCL) are important for the system reliability under postulated accidents. The heat loss and structure thermal inertia may influence the transient behaviors of NCL greatly, so a transient analysis model with consideration of heat loss was developed based on the MATLAB/Simulink to predict the thermal-hydraulic characteristic of liquid metal NCL. The transient processes including the start-up, the loss of pump, and the shutdown of thermal-hydraulic ADS lead bismuth loop (TALL) experimental facility were simulated by using the model. A good agreement is obtained to validate the transient model. The appended structure would provide significant thermal inertia and flatten the temperature distribution in the transients. The oscillations of temperature and flow rate are also weakened. The temperature difference between hot leg and cold leg would increase with the decrease of heat loss, so the flow rate increases as well. However, a significant increase of hot section temperature may cause a failure of facility integrity due to the decrease of heat loss. Hence, the full power of the core tank may also be limited.

PurposeThe relationship between cultural novelty and cross-cultural adjustment of expatriates is often assumed to be negative and linear, while the empirical results for the relationship has been demonstrated by researchers as either negative, positive or absent.Design/methodology/approachThe current research challenges the negative and linear assumption conceptually and empirically and tests a curvilinear relation between cultural novelty and general adjustment. The authors specifically propose and test a theoretical model whereby emotional stability moderates the curvilinear cultural novelty–general adjustment relationship such that the negative effect of cultural novelty on general adjustment is mitigated by emotional stability. Survey data are collected from expatriates recruited from two different host countries, India (N = 151) and China (N = 157).FindingsThe findings provide support for the curvilinear relationship between cultural novelty and general adjustment and the moderating effect of expatriates' emotional stability on this relationship.Originality/valueThis present study makes unique contributions to the expatriate management literature in at least two major ways: first, this study consolidates the otherwise contradictory findings and furthers the understanding on the nature of the effect of cultural novelty on expatriate adjustment. In addition, this research tests a cultural novelty–expatriate adjustment model using expatriate samples drawn from China and India, the two largest emerging markets that capture the demographic-profile changes pertaining to the newly emerging expatriation trends.
