A number of samples of uranium irradiated in NRX have had their reactivities measured in CP-2 by the danger coefficient technique. By means of measurements on enriched, depleted, and poisoned unirradiated slugs, the reduction of the danger coefficient data to changed pile parameters (δη/η and δΣ/Σ) has been accomplished. A brief discussion of the significance of the data has been included.
