Shortly following the accident at Three Mile Island Unit 2 (TMI-2), GPU Nuclear, along with Bechtel Power Corporation nuclear specialists, established a Containment Assessment Task Force (CATF) to assess the radiological conditions of the TMI-2 reactor building of containment. The task force was to devise and execute a series of experiments and analyses to obtain those data necessary for initial entry, containment purge, and containment recovery. The analyses and experiments were designed to assess the following: (1) airborne levels, (2) levels of surface contaminations, (3) magnitude of the basement water source term, and (4) general radiological environment within the containment. The early tasks performed under the CATF were postaccident airborne samples, remote Ge(Li) gamma-ray scans through the containment equipment hatch, remote gamma-ray scans with NaI crystals through spare containment penetrations, radiation survey maps of the containment personnel airlock, retrieval of an actual sample of the water in the containment basement, and remote television and radiation monitors installed through a penetration into the containment.
