.. i 1.0 _ PURPOSE .O
~s 1.1 This procedure identifies the Chemistry outage activities to chemically treat and layup systems, identifies the Health Physics outage activities to reduce radio activity levels in Plant systams and reduce exposure to personnel during an outage, describes the support necessary to complete them and defines the responsibilities for providing suppor,t.
NOTE Outage Types are describsd in Procedure 01000-C, "Maangement Of Outages". 4 1.2 This procedure applies to Type IV Extended forced
_0utanes and Type V - Scheduled outages, depending upon the duration and plant configuration. If e, _II -
Svatem Outage, and g III = Short Forced ug - turn into g e applicaole. - IV outages. this procedure will be 1.3 Durina shutdowns and startups for outages, chemical specifications change. The cleanup or layup of plant -
involved can not be securst: systems may require holds where the pla 1 procedure names that plant equipment.Where possible this, 1' 2.0 F DEFINITIONS " '. -
2.1 ACTION P!ANS = Written outline of actions to be taken and the department responsible for their completion. V' 2.2 STRtJCTURED BRIEFINGS - Briefings or action plans w conducted by Chemistry for departmental personnel and .:
