1.0 PURPOSE The purpose of this inspection is to locally observe accessible equipment for any of the following abnormalities.
1.1 Primary system or process system leakage.
1.2 Excessive noise or vibration of equipment.
1.3 Proper and adequate condition of equipment for extended service.
, 1.4 Undesirable articles / conditions which could jeopardize the ability of the recirculation i phase in accident conditions.
1.5 Any other abnormal or unsafe conditions.

UNIT 2 3.0 PRECAUTIONS AND LIMITATIONS 3.1 A minimum of two people in accordance with the two-man rule when a unit is greater than 350 F, at least one of whom will be a supervisor, shall conduct the containment inspection i per this periodic check (PC). ;
3.2 Remain clear of the reactor cavity edge at all times during power operation. Do not use the walkway at the south end of the reactor cavity because of extremely high neutron exposures.
3.3 Reactor coolant pump compartment inspections should only involve the upper motor platform and be completed as rapidly as possible due to the high radiation levels when at power. Inspections below that level are only permitted as authorized by the radiation work permit.
3.4 Containment entry is made under the guidelines of HP 2.12, " Containment Entry / Exit Procedure." i 4.0 INITIAL CONDITIONS INITIALS 4.1 Ihe Following Should Be Assembled for the Insocction:
4.1.1 Flashlight and inspection mirror.
4 4.1.2 Key to Unit 2 containment and a high radiation area padlock key for regenerative heat exchanger area door.
4.1.3 A plastic bag with clean rags to clean up oil and water or other items in need of wipeup.
4.1.4 Instructions concerning abnormalities and/or special checks to be made per the Operations manager.
4.1.5 Two 500 mi sample bottles labeled for 2T-34A&B samples, a small plastic pail, and 11/16" wrenches for 3/8" Swagelok plugs.
4.1.6 One-liter poly bottle for RCP oil collecting tank drainage.
4.1.7 i'ortable radio.
4.1.8 The Still Video Camera from HP for visual documentation of any problems noted.

UNIT 2 INITIALS 4.1.9 One bottle of snoop for leak check of nitrogen bottle connection.
4.2 An RWP is available.
4.3 Open 2SW-2907 or 2SW-2908 at least 30 minutes prior to and during this inspection.
3 5.0 QFNERAL INSTRUCTIONS 5.1 Hydraulic snubbers should be checked for indications of oil leakage directly below the ,
snubber and by oil level when accessible. If snubber leakage is detected, it must be noted '
for priority attention. DO NOT remove sightglass metal ivers. '
5.2 Refill snubbers with the followine tvoes of oil:
Grinnell snubbers GE-SF-1154 (Blue)
Ankor Holth snubbers GE-SF-1147 (Yellow) 5.3 During periods of normal operation where the containment is unoccupied, the lighting will be secured except for emergency lights.
5.4 Indicate the condition of a valve leakoff by circling the applicable status. When a valve !
leakoffis recorded as anything other than ambient, an accompanying statement must !
include information such as the distance from the valve before the tubing cools, the i amount of packing gland adjustment remaining, etc., to aid in the subsequent evaluation of l the condition.
5.5 When taking air flow readings on the accident fan cooler units, zero the manometers prior to taking differential pressure readings. It may be necessary to add oil to the manometer (Miriam red oil).
5.6 All operable containment cooling fans should be operating during the containment i inspection so they can be visually and audibly surveyed. This includes both normal and i accident fans. Individual fan units may be left secured until they are inspected. This will l
minimize problems with the RCP seals.
5.7 1 Work orders must be written and referenced in the PC so that subsequent surveillance may be performed on any abnormality noted during'the inspection. The white work order initiation tag should no.I be used in containment. ,,

UNIT 2 5.8 The general comments for an area should include a statement concerning leaks, safety hazards, fire hazards, the condition of fire hose stations and cleanliness, if abnormal conditions exist.
5.9 Review the last inspection :o identify previous deficient areas and to determine if corrective actions have been accomplished or are outstanding.
5.10 Record the final flow setting and throttle valve position of the fan motor coolers during the previous inspection for comparison and/or compensation during this inspection.
NOTE: 2W-1A1, 2W-1B1, 2W-1C1, and 2W-1D1 are to beflushed every inspection.
2W-1 Al Valve position Flow 2W-1B1 Valve position Flow 2W-1Cl Valve position Flow 2W-1D1 Valve position Flow 5.11 The El. 66' personnel hatch is used for normal entry and exit of the containment. The El. 26' personnel hatch is available for emergency exit whenever personnel are in containment.
5.12 The Still Video Camera shall be bagged and left in the El 66' personnel hatch during the l containment inspection. Anytime that the use of the camera is warranted, it shall be retrieved and used appropriately. The pictures are intended to give a better description of the concern or defect so that corrective action may be planned without additional l containment entry for work plan information. Camera uses include but are not limited to:
Wet boric acid leaks, equipment problems, WOs, safety hazards or any abnormal conditions.
