The fuel rod performance of enhanced thermal conductivity UO2/graphene composites is investigated through a LBLOCA analysis. The benefits increased monotonically with increasing thermal conductivity in terms of reduced fuel center temperature and PCT. The performance of the UO2/graphene composite fuel is assessed in OPR-1000 (Optimized Power Reactor-1000) during a LBLOCA. Graphene can be a promising material for developing advanced nuclear fuel because of its property about the high thermal conductivity and low absorption cross section. The results confirm a LBLOCA performance related to PCT of the UO2/graphene composite fuel and its potential while maintaining large safety margins.

Herein, we introduce a boron nitride nanosheet (BNNS)-reinforced cellulose nanofiber (CNF) film as a sustainable oxygen barrier film that can potentially be applied in food packaging. Most of commodity plastics are oxygen-permeable. CNF exhibits an ideal oxygen transmittance rate (OTR) of <1 cc/m2/day in highly controlled conditions. A CNF film typically fabricated by the air drying of a CNF aqueous solution reveals an OTR of 19.08 cc/m2/day. The addition of 0-5 wt% BNNS to the CNF dispersion before drying results in a composite film with highly improved OTR, 4.7 cc/m2/day, which is sufficient for meat and cheese packaging. BNNS as a 2D nanomaterial increases the pathway of oxygen gas and reduces the chances of pin-hole formation during film fabrication involving water drying. In addition, BNNS improves the mechanical properties of the CNF films (Young’s modulus and tensile strength) without significant elongation reductions, probably due to the good miscibility of CNF and BNNS in the aqueous solution. BNNS addition also produces negligible color change, which is important for film aesthetics. An in vitro cell experiment was performed to reveal the low cytotoxicity of the CNF/BNNS composite. This composite film has great potential as a sustainable high-performance food packaging material.
