An improved adaptive constraint aggregation for integrated layout and topology optimization
TL;DR: In this article, a Kreisselmeier-Steinhauser (KS) function based adaptive constraint aggregation approach is proposed to avoid using large numbers of non-overlapping constraints defined by means of the previously proposed finite circle method (FCM).

A Multi-point constraints based integrated layout and topology optimization design of multi-component systems
TL;DR: In this article, a new multi-point constraints (MPC) based method where the rivets or bolts connections between the components and their supporting structures are introduced is presented, where the displacement consistence involved in the MPC is strictly maintained which makes the components to carry the loads together with the supporting structures.

New Spacer Grid to Enhance Mechanical/Structural Performance
TL;DR: In this article, a new spacer grid form and its manufacturing technology were suggested for enhancing the integrity of the FR support and the SG crush strength by using a systematic optimization technique without significantly increasing the pressure drop across the reactor core.
