VCM 1.4* ppm, VCM 3.3* ppm, VCM Source Employee unplugged the blowdown tank transfer line from the old unit to the new unit. Employee worked near a leaking VCM pump discharge valve in the old unit - same source as that for the Reactor Operator exposureof 1.4 ppm (see below). Employee checked VCM leaks in old * unit. Employee checked for VCM leak in old unit, finding the west VCM charge pump discharge valve stuck. Employee manually drained the K.O. tanks and the blowdown tank in the new unit. ABDOO136671 OVEREXPOSURES - (Continued) Job Class Reactor Operator Expsoure 3.5* ppm, VCM Chief Operator Reactor Operator 5.7* ppm, VCM 20.1* ppm, VCM *Respiratory protection worn. Source Employee dumped two coarse batches (741 & 742 reactors) and sampled 743 and 745 reac tors for coarseness. Employee isolated a vacuum pump having a blown seal. Employee changed VCM filters in the new unit filter packs. 'Jerald Uptain rah
