On December 2, 1981, 10 CFR 50.44 was amended to require plants that do not have recombiners to have the capability to install external recombiners.'ollowing review of the amended rule, Turkey Point elected to install piping and electrical service for the installation of an external hydrogen recombiner in accordance with 10 CFR 50.44. As stated in the NRC Inspection Report 50-250/251-90-13, Turkey Point developed an off-normal procedure providing instructions on how to obtain a hydrogen recombiner     if the need arises.
