Abstract of Results of Examinations and Tests ASME Class 1 B-B An acceptable indication was found on the Pressurizer bottom head to shall girth weld RC E-10 01.
The indication was determined to be slag inclusion. This was verified through review of construction radiographs.
B-G-2 Inspection of bolting yielded 10 valves being rejected due to existence of boric acid residue. Areas were cleaned and subsequently re-examined.
During plant start-up from refueling, a walkdown of Class 1 piping was conducted for evidence of leakage.
No leakage was identified.
Two valves were rejected for bolting that lacked full thread engagement.
Engineering evaluation found them acceptable for continued service. This condition was determined to previously exist since plant construction.
B-J Three welds had UT indications which were evaluated as root geometry.
l Two welds had multiple UT signals due to root reflector and beam redirection to the ID due to columnar grain structure of the weld metal.
Six welds exhibited UT beam redirection due to dendritic weld structure.
l One weld had numerous PT indications on the weld area and base l
material.
Surfa:e conditioning by flapper wheel removed the indications.
One weld had an unacceptable linear indication that was successfully re-examined after surface conditioning using a_ flapper wheel.

1,4. Abstract of rsesultsofExaminationsandTests(continued)--
ASME Class 2, 3._and NF C-A Two girth welds were examined by UT on the "B" RHR heat exchanger.
1 The 0* longitudinal scans and the 45' shear wave scans found no.
indications in the two weldments other than geometrical. These geometrical indications were determined to be internal baffles and nozzle supports and confirmed with preservice data and fabrication drawings. The 60' shear wave scan on the bottom head-to-shell weld recorded midwall and ID reflectors intermittently,-over 360*of the vessel weld. The ID reflectors were determined to ha the attachment welds (these are the same as noted on the 45' scan). Utilizing enhanced techniques, the midwall indications were evaluated to be metallurgical in nature, originating from the grain structure and not from any discontinuity.
C-8 Two nozzles were examined by UT on the "B"-RHR heat exchanger. The longitudinal seam on nozzle "A" displayed two indications on its entire examined length. -They were evaluated to not be indications as the signals could be dampened at the OD surface on top of-the weld.
Both nozzles showed two indications from the axial scans.. One indication was due to reflection from the face of the weld and/or reinforcement pad surface. The other indication was determined to be a root indications from the ID of the nozzle-to-shell weld.
PT results from these two nozzles were rejectable due to' weld bead-roughness. These welds were not prepared for a solvent removable penetrant examination during construction.
Welds required grinding in-order to achieve an acceptable penetrant examination. A visual examination was performed in order to verify design dimensional requirements of the weld after grind.ing.
C-C PT examination of the "B" RHR heat exchanger support skirt yielded rejectable results due to surface condition and rough bead placement.
Grinding was required to achieve a successful re-examination.
l C-F-1 One weld had a UT indication which was evaluated as counter bore geometry.
Three welds exhibited UT beam redirection due to dendritic weld structure.
One weld had two indications. One was evaluated as counter bore gecs try, the other as beam redirection due to dendritic weld structura.
Seven welds required surface conditioning by flapper wheel in order to achieve a successful PT examination.
C-F-2 Seven welds exhibited UT indicationt which were evaluated as root geometry.
One weld had a UT indication that was evaluated as OD geometry'and verified by aampening.

1,4. AbstractofResultsofExaminationsandTests(continued)
ASME Class 2. 3. and NF C-F-2 One weld had three indications. One was evaluated as OD geometry,-and (con't) the two evaluated as root geometry.
One weld required surface conditioning by flapper wheel to achieve a successful MT examination.
D-A The Class 3 Service Water Functional Test was acceptable in the category of leakage, but was unacceptable _for surface corrosion.
All other pressure tests met the required acceptance criteria.
1 NF Four hydraulic snubbers were found with unacceptr'.',e fluid conditions..
These snubbers were determined to be operable _and evaluations performed to determine system effects.
Additional component supports were identified as having failed visually (i.e., loose _ nuts, light corrosion). _ Evaluations were perfctmed and the sup) orts were determined operable, and did not fall within IWF-3410. Worc requests were generated to correct these conditions and to perform VT-3 and VT-4 examinations to verify their_
completeness,
- 15. Abstract of Corrective Measures Welds and Bolted Components No corrective measures were required as a result of UT examinations. All recorded indications were evaluated and determined to be related to geometry or weld metal structure.
Surface examinations (PT & MT) that exhibited indications were determined to be mostly grinding marks and were resolved by surface conditioning with a fla)per wheel.
"B" RHR nozzle and skirt welds required grinding due to their rougl surfaces and bead placement.- Their examinations were also acceptable once gered for surface examination.
Visual examination-of bolted components yielded similar conditions.. A few valves required cleaning to remove evidence of boric acid in order to meet the acceptance criteria.
From a previously existing condition two valves were found to have bolting which did not meet full thread engage, ment criteria.
Engineering evaluation determined them to be acceptable for continued service.
The above examinations conducted during this-ISI did not result in any ASME Section XI repairs.
Pressure Testino i.
During testing of the Service Water System,'it wasi noted that an unacceptable
~~
quantity of corrosion existed on the piping OD. Engineering _ evaluated the condition and determined it to be acceptable for continued operation with a further evaluation of conditions to be reviewed next refueling.

W/R 91 WOO 4238 Steam generator snubber 1-MS-RM-SGA A had functional test results outside allowable test tolerances of the procedure.
It was discovered that tt.is snubber also had initial test results outside the Vendor's tolerances.
They reviewed and accepted the results.
NHY(Seabrook)Engineeringreviewedinitial and refueling outage results, accepted them, and issued a design document to correct the test records.

Four hydraulic snubbers were found with unacceptable fluid conditions.
These snubbers were determined as inoperable and evaluations were performed.
Additionalcomponentsupportswereidentifiedashavingfailedvisually(i.e.,

Plaat Technical Specifications reluired 10% of the mechanical'and hydraulic snubber population to be functionally tested.
Fourteen (14)representedthe 151 population, and they had acceptable functional tests.
Three failures occurred during testing of the remainder, and they occurred on PSA 1/2 sizes.
Eighteen (18) additional PSA 1/2 snubbers were tested with no additional failures.
One steam generator snubber had test results outside test tolerances.
Engineering reviewod the-test data-and manufacturer data, determined the results acceptable,.and issued a design document correcting the test results.

The Service Water tests failed VT-2 visual exaaination due to excessive surface corrosion.
Engineering evaluation determined the-piping to be acceptable for continued service with measurements verified during next refueling. All other tests were acceptable.
