    Abstract

    Over the last decade, several international thermalhydraulics benchmarking efforts have been carried out to support the development of the Generation IV supercritical water-cooled reactor (SCWR) concept. These benchmarking efforts aimed to assess the readiness of computer codes to predict the thermalhydraulics behavior of supercritical fluids for nuclear fuel assembly applications. The results from the benchmarking also shed light on knowledge gaps. Throughout the years, several advancements in this area have been achieved, resulting in relevant conclusions and observations. Furthermore, experimental campaigns have been carried out worldwide to further our knowledge on the thermalhydraulics of supercritical fluids. The nuclear industry uses the subchannel approach to study the thermalhydraulics behavior of nuclear fuel assemblies in detail. In Canada, the subchannel code advanced solution of subchannel equations in reactor thermalhydraulics-pressure velocity (ASSERT-PV) is the qualified code for subchannel applications. ASSERT-PV was modified to handle supercritical conditions, resulting in an interim code version. This publication presents relevant subchannel analyses using the interim supercritical version of ASSERT-PV for fuel assemblies cooled with supercritical fluids.

    ABSTRACT

    This study examined whether grandparental support is a protective factor for children's socio‐emotional development in the context of adversity. Using longitudinal data from the Millennium Cohort Study, we investigated the effects of grandparental support across development in children with and without adverse childhood experiences (ACEs). Socio‐emotional development was assessed with the Strengths and Difficulties Questionnaire when children were aged 3 years (N = 10,186), 5 years (N = 10,412) and 7 years (N = 10,551). Parent‐reported grandparental childcare, coresidence and financial help were assessed and parents reported on the occurrence of five ACEs: physical and emotional abuse assessed with the Straus’ Conflict Tactics Scale, parental mental illness assessed with the Kessler scale, domestic violence and parental separation. We found that children with relatively higher levels of ACEs showed more prosocial behaviour and less externalizing problems when they received grandparental care compared to non‐grandparental (in)formal care, but only at age 3. By age 7, children with higher levels of ACEs receiving grandparental care showed less prosocial behaviour and more externalizing problems. In addition, grandparental financial support at age 3 was related to more externalizing problems. Post‐hoc analyses showed that internalizing and externalizing behaviours at age 5 were related to an increased probability of grandparental childcare at age 7, indicating that children's socio‐emotional problems trigger grandparental support. Our findings point to a protective effect of grandparental care on children's socio‐emotional development at age 3. Our results highlight the importance of going beyond the nuclear family towards the impact of the wider family network when examining children's socio‐emotional development.

    Research Highlights

    Three‐year‐old children with high levels of adverse childhood experiences (ACEs) show more prosocial behaviour and less externalizing behaviour when they receive grandparental care.

    Grandparental care has therefore protective effects on young children's socio‐emotional development in the context of family adversity.

    Grandparents respond to children's socio‐emotional problems and family adversity by increasing financial support and involvement in care.

    These findings underscore the importance of going beyond the nuclear family towards the impact of the wider family network when examining children's socio‐emotional development.
