High power PWR undergoes meltdown at the moment of block loading

In the old version, the production rate of hot coolant in PWR was limited by the core temperature, so a coolant buffer of 128000mb could adapt to the requirements of PWR at that time; After the addition of the PWR Heatsink, everything changed.
Please take a look at this reactor. When the control rods are stretched to 70%, the production of high-temperature liquid sodium per tick has reached 30000 mb, while the reactor fluid buffer is only 128000 mb; Considering the consumption of each tick, this reactor will consume all the coolant in just 3 tick without cutting off the coolant, and an additional 1 tick will complete the heating and melting process, which is extremely dangerous.
At the same time, due to the loading issue of the MC block, there is a short period of time when the coolant cannot be exchanged between the PWR and the outside world at the moment of entering the world; The specific reason is still unclear, but the visible fact is that the high-power PWR melted down at the moment it entered the world.
Therefore, I propose to add a mechanism similar to a PWR Heatsink to enhance the reactor fluid buffer; In my opinion, relying on PWR Coolant Channel or adding new blocks are feasible options.
In fact the loading problem is probably relevant to chunk loading order. If the chunk that the PWR is in loads before the chunk the cooling facilities is in, the PWR will not be cooled until the latter chunk loads. The problem could be avoided by building the ractor and its cooling facilities in the same chunk.
