VC Closeout

Paul, The VC was closed out for exiting Mode 5 (OAP-007) at 0426 hours0.00493 days <br />0.118 hours <br />7.043651e-4 weeks <br />1.62093e-4 months <br />. Below are some of the resolutions:

1.

Hanging conduit on VC wall in rear of hatch laydown area was restrained.

2.

Scaffold on right side of hatch laydown area was strengthened.

3.

Barrels of rigging that are on top of Iodine Filter Fans are previously evaluated.

4.

A nozzle was installed on the fire hose on 33 SG biowall.

5.

The Dry Cask guys took care of numerous cleanup items: tie wrap near cavity drain, Caution tape hanging from light, knee pad in dog house, etc.

6.

33 RCP: loose u-bolts on the CVCS line were tightened, floor grating clamp was tightened, unistrut for vibration probe cables was tightened, standpipe LT sealtite was repaired.

7.

34 RCP: the boron at the packing of RC-593 was cleaned off. This valve and others with identified packing leaks were added to an OCC list of valves to check at NOP/NOT. The crooked hanger was inspected and evaluated by engineering and determined to not be an issue.

8.

The socket that was on the ECCS line between 33 RCP and the RHR Hx Room was retrieved.

9.

As per the OCC, those orange tags on the bedspring (which I have seen over the years) are previously evaluated.

10.

I've notified the only two guys who have the possibility of performing the Hot Torques In the cavity to capture the rope and yellow tape on the head.

11.

Rad Waste cleaned up the oil beads around 33 RCP.

12.

As per the OCC, the following scaffolds / railings are evaluated for power operation: Rx Sump, 31 RCP, 32 FCU, 33 FCU and railing at ledge between 33 RCP and the RHR Hx Room.

After I exited the VC and was writing up our list, the OCC, VC Coordinators, etc were working on the list that Russ Long had generated prior to ours. We had a meeting in the OCC at 0015 hours1.736111e-4 days <br />0.00417 hours <br />2.480159e-5 weeks <br />5.7075e-6 months <br /> (with all groups) to address all of the items. A large team reentered the VC at 0100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> to perform the work. As I mentioned earlier, the valves with packing leaks from both mine and Russ' list (and from other sources) are on an OCC list for NOP/NOT.

VC Comments on walkdown w/NRC Trash receptacle behind 80ft airlock inner door incore drives hepa and garbage Air Sampler & ladder by bottom of stairs to 95ft 10 & 5 Path area BA buildup above 10 path on Swagelok line before the 5 path, this is not the drives them selves All 5 path lines marked with duct tape 32 FCU Scaffold by SW SW insulation only part on MCC-38 Swagelok down stream on SI-103 has dried boron - Evaluate Transmitter Room 839H has an active packing leak (water on valve)

Fr-415 High Side swagelok fitting has a leak (currently dry @ 0 psig) but has leaked down on to transmitter lines below, boron is fresh.

MS Line Area 33 Main Steam line lower bracket appears to have an oil puddle on the top of it (visible on the platfornm above the 68' 33 FCU Scaffold by cooler SW insulation only partially installed RHR Hx Room Yellow bootie on support beam about 20ft in overhead - Rad Waste looking at ways to retrieve it ?

746/899A U-bolt has a loose nut on the top 899B has a packing leak (dry) 747 has a packing leak (dry) 46' tools in area of 200B Caution Tape in overhead near 31 Accumulator Marinite boards by column 14 have heavy debris on them ICW Nut missing in IR Sump

Scaffolding by RCDT - long term Lead on RCDT 32 Cold leg has minor ( -8") duct tape in overhead - can't reach Permanent light in Recirc sump room's appears to be held on with electrical tape Hole in sealtite (- 1/4/4") in recirc sump room for FT-640 Recirc Discharge valve packing leakoff line is bent Boric Acid residue near VC Sump Next to 34 RCP (on cavity drain down pump area) there is -8" of duct tape on an SI line Large Amount of Boric Acid crystals under the Xfer Canal behind the locked gates SI-2175 unlocked (chain hanging next to valve) and has Boric Acid leak on packing (dry)

WD-510 has Boric Acid on it (dry) might be from above Black Tie wrap in Overhead (near cavity drain flange looking towards 32 RCP) holding unknown Swagelok line Letdown Line (right off loop, before CH-362) has broken and crumbling insulation Minor rust and corrosion on BD-3-2 appears to be from a possible packing leak Missing 3 clips on 31 S/G mirror insulation, on highest platform off 46' (second platform)

Boric Acid buildup on Swagelok line above incore flow grating against bioshield wall (about 10' up)

Rx Sump Big Paint flake on wall under Rx Vessel (8" diameter) about 4' above floor - remove When was the last time this (and other) permanent scaffolds were inspected (NRC question)

Is it acceptable to use rubber matting under the scaffold's feet?

Heavy corrosion on reactor. sump pump - need wrt 31 RCP Lower platform Scaffold - looks permanent Old oil leak on stud #4, have eng look at this 33 RCP Lower Platform Old oil on stud 11 is this ok?

95, Ladder box not chained and locked (needs to remain open for ladder from cavity)

Doghouse 2 pieces of loose lagging on deck plate just inside doghouse
