None of the indications showed any significant corrosion or any other defect that would adversely affect the integrity of the containment structure. Conditions that led to the degradation are age, occasional containment humidity, and equipment bumping the containment wall during refuel outages. All indications were determined to be acceptable for continued service with no corrective actions and no further evaluation required. The affected components will be periodically inspected under the site IS1 program. The following indications are of a similar type, extent, and under similar service conditions: Summary # Category ( Comp. Report # Site Eval # 406023 E-C, Cooling Wtr. Penetration I C37A 2008U008 Review by site

The UT thickness reports were submitted to the site IWE engineer for evaluation. All readings were on FCU supply and return penetrations. Site drawing NF-38398-2 indicates the penetrations were fabricated from nominal 8 inch diameter schedule 160 carbon steel pipe. 8 inch carbon steel pipe has a specified wall thickness of 0.906" with a ' mill tolerance of 12.5% resulting in a specified minimum thickness of 0.781". The minimum reading among the 8 readings taken on each of the 8 penetration is 0.868". The minimum reading of 0.868" is significantly greater than the specified minimum thickness of 0.781". As a result, there is no indication of significant degradation. No corrective actions or further evaluation is required. The affected components will.be. periodically inspected under the site IS1 program.

Damage was the result of tools and equipment impacting the moisture barrier during the refuel outage. All damage was repaired under work order 282764 and re-examined satisfactory. No corrective actions or further evaluation is required. The moisture barrier will be inspected each outage under SP 1123.

Two flanged containment penetrations 27C1 and 27C2 were found to have inadequate thread engagement of the studs to nuts. The penetrations are listed as ILRT pressure sensing lines. It is not known what led to the condition. The studs were replaced under work orders 356008 and 356009 and re-examined satisfactory. No corrective actions or further evaluation is required. The affected components will be periodically inspected under the site IS1 program.

NUCLEAR MANAGEMENT COMPANY INSERVICE INSPECTION PRAIRIE ISLAND UNIT 1 CYCLE 24

SUMMARY

REPORT Section 5. Pressure Tests The following class 1 and class 2 scheduled pressure tests were conducted during Unit 1 cycle 24. All indications were evaluated and corrective measures performed as required by TWB-3142 and MA-5250. LOCA Hydrogen Chemical SP 1168.16 Chemical Volume C-H and Volume Control 2 107865 In Progress* Control System Pressure Test System SP 1168.17 Main and C-H Feedwater System 2 107903 211312008 Aux Feed Pressure Test SP 1168.21 BAST Boric Acid C-H 2 153463 611312007 System Pressure Test The class 2 portions of this pressure test are in progress and will be completed before the end of the period. Boric Acid Leakage Identified at Bolted Connections Eleven code class components were identified as having boric acid indications at bolted connections in conjunction with refuel outage 25 pressure tests or boric acid inspections. Per the H2 Boric Acid program document, boric acid indications found as a result of a boric acid inspection are evaluated as if found during a pressure test. In each instance corrective actions were initiated and the component was evaluated and found suitable for continued service. In accordance with Code Case N-566- 1 "Corrective action for Leakage Identified at Bolted Connections" evaluations considered:

The number and service age of the bolts; Bolt and component material; Corrosiveness of process fluid; Leakage location and system function; Leakage history at the connection or other system components; Visual evidence of corrosion at the assembled connection.

SUMMARY

REPORT Section 6. Snubber Inservice Testing and Preservice Examinations (3 page)

Summary description of snubber visual inspection and Functional testing for the time period of: June 2006 to February 2008 There were a total of 28 snubbers tested in 1R25: 22 functional tests and 6 B.O.P. snubbers tested due to a failed constant support. All testing was SAT; see the following two pages of the 90 day summary report. Seventeen snubbers were of the Basic-PSA hydraulic type, which had spares rebuilt and tested prior to installation. The removed Basic-PSA snubbers all tested SAT in the as found condition. There were two ITT snubbers that were tested, rebuilt and re-installed. One Paul Monroe snubber was functionally tested and re-installed. Two steam generator valve blocks were replaced with rebuilt spares. The rebuilt spares and the as found valve blocks tested SAT. No scope expansion from failed testing resulted during 1R25. Testing was performed by a Basic-PSA field representative. The snubber visual inspections were performed per SP 1171 and TP 1535 by LMT, which resulted in no scope expansions. All cylinders contained hydraulic fluid, there was no evidence of leakage and no snubbers were found locked up.
