WebFeb 21, 2024 – As with many nuclear reactors, the RBMK used the heat of fission to create steam that powered the movement in an electrical generation system. Unfortunately, the positive void coefficient designed into the RBMK is unsafe and can lead to meltdowns, so use of safer designs is encouraged. WebJun 13, 2024 · How they came to bring the reactor to that condition is a tragedy of failure to understand what they didn't know and being pushed by those that thought they knew everything. None of them were ever told, or didn't appreciate how unstable the RBMK (in its original configuration) could be at low power with 'inadequate' shut-down margin and …

WebThis, basically, is the rate of change in reactivity as the cooling medium (water) boils inside the reactor and forms steam bubbles (i.e. voids). Void coefficients can be negative, meaning as the water boils the reaction slows down, or positive, meaning as the water boils the reaction speeds up. WebThe poisoning of Xe-135 arises when the reactor is shut down, see Fig.2. The neutron flux (reactivity) decreases drastically (point 2 in Fig.2) while Xe-135 production increases due to the continuous decay of I-135 see Fig.2. … tips on ironing fabric
