I Dccision point for E-0 to ES-I.1 Administrative N Valid decision oint Decision point for transition to 3208 from Administrative N Valid decision.

safety Condensate high temperature, no procedure Administrativc N Is this a problem with ES-L. or all EOP's? Is there to get to long recycle something in 3550 that would have helped?

Decision to not put CTMT vac pump in Administrative N Good decision; Would other SMIUS made that choice service with potential RCS leak. Possible rupture of PRT and CMS22 alarms. Traincd to put vacuum pump in service, it is even OK m

._ _ .with a known RCS leak.

Used FR-I. I to draw bubble Administrative N Good decision Letdown temperature hi, VCT at 130, RCP Administrative N Need to interview US and RO. When did this occur?

trip at 135 Was it a problem with procedure or operator action?

Administrative N Old tool unsafe, new tool untested CBI-Could not get into control building Administrative N PEO's arc sent to control room after a SI. No training occurs as to correct path to enter control room. IE, thru the HVK chiller room.

Operations personnel are trained that Administrative N Review of the ESK indicates that the thermal overloads MSS*MOV74's can only be stroked 7 times are bypassed whcn the valve pushbutton is held. The 7 an hour, Valve was stroked many more strokes is a common engineering calc. But is not a times than that* physical limit. Need lo compare this to training on the 6

Uncertain about correct time to take Iodine Administrative N One part of the crew felt a change had recently occurred a sample moving the requirement to I hour. Need to talk with Chriss Miller and see if any read and signs went out on this.

Validate why this occurred. W No clean way to get into 3208 from ESIl , Administrative N Make similar changes to ES-I.I that exist in ES-0.1 a) compare it to ES-0. 1 Chemistry priorities for LiOHl and SIG Administrative N Distraction to operations.

chemicals, conflicted with priorities to move plant. 3 Aux boiler procedure has problems. Administrative N Consider a GA from EOPS _

Speakers hard to hear Administrative N Is there any PM to check the sound on all speakers- An I actual DB check?

EOF concerned about no sample on D S/G Administrative N Why did the BOP use'the SIG with no sample capability.

but that was SIG that was steamed the most Arc the operators aware of the concern of dumping steam with a small steam generator tube leak.

Decision to skip end of ES-1.1 to get to Administrative N Review skipped steps. Are they appropriately located.

3208 Should they have been done.

Decision to not classify at A lert for Administrative N This is an issue at U2. Need to check with EP to validate charging leak SM correct decision OP 3330C has good guidance for reducing Administrative. N Review EOP/AOP's determine if procedure links need to pressure in ctmt, but nothing sends us there be created PORV light not cycling Equipment N Review of real time indicates that the PORV's did cycle.

Discussion with the RO and the US indicates that the PORV light and alarm did come in. Many times the green light did not go off because of the speed of the
