%5_icct : REACT 0P. SU!LO!NG PL'.'.'GE !!ATUS Purging of the reactor buildine; at:-csphere was shutdown at 1:a5 a.m. todcy.
The decision to shutdcan was made so that reactor builoing cir :.a:nDies could be ta'r,en withc.ut the perturbation from the air flow into or na: of tne reactor bui'. fing.
Reactor buldling air samples wera taken n 4:00 a.m.,
5: 00 a.m. and at C:45 a.n..
The Naseme'it resTJ1ts were 1. 7x.0-0 uCi /cc, l. Ev 10-0 v.i /'.c am. 1.89x10-4 uti/cc.
respectively. This infunnation 1s Leing reviewed alcng with HPR-Ei3A lU.)nitoring data to evaluate the total release of Kr-85 and what quantit/ of Krypton gas re ains to be purged.
The :ccified reactor building ;;urga sy:: tem. w:s purgin.; at 16,~00 cf : with the stack ficw rata of 104,000 cfm up to 1:45 a.m.
The t::t:1 release as of the snutduwn is 3a,154 Ci, baseo on stack flow rate ano c -asure; s: ck curAentration usir.g HPR-211!A v s. lues.
Additional reports on reactdr building purging will be updated on a daily basu.
The NRC Region ! mobile laboratory will continue to be used to verify the licensee's analytical results on particulate content.
