This paper presents a calculation of transient events in the Hanford piles due to the build up of fission product nuclides with a very large neutron absorption cross-section. In particular it was found after operation of the first major pile that Xe{sup 135} was a short lived isotope which built up in the pile, and which possessed a very large cross-section. The dynamics in number density of this isotope has a major impact on the reactivity behavior of the piles, and in particular on the start-up behavior following transient shut-downs.
