There is plenty of Lead. I did that calculation a while back. Haven't done the calculation for Boron. Note that if the sole purpose of the Boron is for neutron shielding, then it can be replaced with other substances. If it's involved in a p-B11 reaction then the energy yield of the reaction is high enough to allow for extraction from very low grade sources, so it would still last for millions of years.
