TerraPower Isotopes Chooses Philadelphia's Bellwether District for $450 Million Actinium-225 Plant

Backed by state grants with long-term tax benefits, the first East Coast site aims to expand supply of a scarce cancer-therapy isotope.

Overview

  • The company will lease 250,000 square feet at the former refinery site to manufacture actinium-225 for targeted alpha therapies.
  • Pennsylvania committed $10 million in grants, and the Keystone Opportunity Zone status provides tax advantages through 2043.
  • Officials project about 225 full-time jobs in Philadelphia over the next three years, with no construction timeline announced.
  • TerraPower Isotopes selected Philadelphia from more than 350 candidate locations, citing proximity to the region's life-sciences ecosystem.
  • Global output of actinium-225 remains extremely limited, described by Canadian Nuclear Laboratories as less than a grain of sand annually.
