THE PROCESS CONTROL PROGRAM

- 1.30 The PROCESS CONTROL PROGRAM (PCP) shall contain the provisions to assure that the $0LIDIFICAT10N of wet radioactive wastes results in a waste form with properties that meet the requirements of 10 CFR Part 61 and of low-level radioactive waste disposal sites. The PCP shall identify process parameters influencing $0L101FICATION such as pH, oil content, H.,0 content,solidscontent,ratioofsolidifIcationagenttowaste ahd/or necessary additives for each type of anticipated waste, and the acceptable boundary conditions for the process parameters shall be identified for each waste type, based on laboratory scale and full scale testing or experience. The PCP shall also include an identification of conditions that must be satisfied, based on full scale testing, to assure that dewatering of bead resins, powered resins, and filter sludges will at the time of disposal, within the result in volumes of free water, low-level radioactive waste disposal limits of 10 CFR Part 61 and of sites.

PURGE - PURGING 1.31 PURGE or PURGING is the controlled process of discharging air or gas from a confinement to maintain temperature, pressure, humidity, concentration or other operating condition, in such a manner that replacement air or gas is required to purify the confinement.

RATED THERMAL POWER 1,32 RATED THERMAL POWER shall be a total reactor core beat transfer rate to the reactor coolant of 3293 EIT. l 15 Amendment No. 42 FERMI - UNIT 2 I I -,Il1 ll l
