There are many supercritical OTUs that exhibit "Alligator Cracking", i.e. waterwall circumferential cracking and many subcritical OTUs have experienced short-term waterwall tube failures due to critical heat flux (CHF) events caused by tube-to-tube flow unbalances.

Do you think the spiral-wound design would be a solution to these problems?
