Inaccessible Areas Evaluation 50.55a(b)(2)(ix)(A) The Code of Federal Regulations, Title 10, Part 50.55a(b)(Z)(ix)(A) states: "For Class MC applications, the licensee shall evaluate the acceptability of inaccessible areas when conditions exist in accessible areas that could indicate the presence of or result in degradation to such inaccessible areas. For each inaccessible area identified, the licensee shall provide the following in the IS1 Summary Report as required by IWA-6000: ( I ) A description of the type and estimated extent of degradation, and the conditions that led to the degradation; (2) An evaluation of each area, and the result of the evaluation, and; (3) A description of necessary corrective actions." Refuel cavity leakage in 2R27 (cycle 26) resulted in water in contact with the containment vessel. Level instrumentation showed leakage into the containment RHR suction sump indicating refueling water in contact with the containment vessel. There was also water observed in contact with the containment vessel when concrete was excavaged in the reactor vessel sump to facilitate VT and UT examination of the containment vessel (AR 01337188). These indicaitons of leakage are considered a condition in an accessible area that could indicate the presence of or result in degradation of inaccessible areas. As such, this evaluation is included in the IS1 summary report as required by 10CFR50.55a(b)(2)(ix)(A). I . A description of the type and estimated extent of degradation, and the conditions that led to the degradation. The site believes there is no significant degradation of the steel containment vessel, the containment concrete, or steel concrete reinforcing bar. In December of 1998 Automated Engineering Services Corp (AES) performed an evaluation titled "Evaluation of the Effects of Borated Water Leaks on Concrete, Reinforcing Bars, and Carbon Steel Plate of the Containment Vessel". The evaluation concluded that the effect of borated water leaks on the structural materials in containment (concrete, reinforcing bars, and containment shell plate material) is in the worst case minimal and does not affect the capability of the structure to perform its intended function. In addition to the evaluation, a section of concrete was removed from the RHR sump in 1998 to allow direct examination of the steel containment vessel. This examination showed no indicaiton of corrosion or pitting. The 1998 evaluation was reviewed by AES in 2R24 to account for leakage experienced from 1998 to the fall of 2006. This review determined that "The basis and conclusions developed in the Reference 1 report are still valid and in my opinion the integrity of the structural components (concrete, rebar and containment shell) are not compromised." In 2R25 (fall of 2008) a section of concrete was again removed from the RHR sump to allow direct visual examination of the containment vessel and UT thickness readings of a known wetted area. The vessel showed no visual indicaiton of corrosion and all thickness readings were above the nominal plate thickness. It is believed the RHR sump location would be the most susceptible to corrosion as it has the m o s t frequent history of wetting and is in close proximity to the concrete surface allowing greater oxygen exposure. A lack of significant corrosion in the RHR sump provides a high level of confidence there is no significant corrosion in other areas of the containment vessel. In addition, approximately an 18' x 2' area of the lowest accessible containment vessel plates were UT scanned with all readings above the nominal plate thickness. In March of 2009 Dominion Engineering performed an independent evaluation titled "Evaluation of Effect of Borated Water Leaks on Concrete, Reinforcing Bars, and Carbon Steel Plate of the Containment Vessels at Prairie Island Units 1 and
Inaccessible Areas Evaluation 50.55a(b)(2)(ix)(A) 2". Consistent with the previous AES evaluation, this evaluation also concluded that degradation of the containment vessels would likely be minimal. In 1R27 (spring 201 1) and 2R27 (sring 2012) concrete was excavated from the unit 1 and unit 2 reactor vessel sumps to allow direct visual inspection and ultrasonic thickness measurement of the containment vessels. The unit 2 excavation showed wetness believed to be from leakage of the segmented seal between the refueling cavity floor and the reactor vessel. In both cases, the containment vessels showed no visual evidence of degradation with actual thickness readings above the nominal 1.5" design thickness. Based on the results of the 1998, 2006 and 2009 professional engineering evaluations indicating no detrimental effects of refuel cavity leakage on the containment vessel, and recent visual and thickness examinations of the containment vessels of both units showing no degradation, there is a high level of confidence of no significant degradation of the unit 2 containment vessel. The condition that could indicate the presence of or result in degradation is refueling cavity leakage that has resulted in borated water coming in contact with the steel containment vessel. Refueling cavity leakage into the unit 2 RHR sump was noted in 2R24 (fall of 2006), in 21325 (fall of 2008), 2R26 (spring of 2010) and 2R27 (spring 2012). In all cases there was indication of leakage entering the RHR sump through the concrete at the containment vessel near the RH suction lines. In 2R27 leakage was also observed in the concrete excavation of the reactor vessel sump (AR01337188). The 2R24, 2R25, and initial leakage rate in 2R26 was approximately 1 gallon per hour (gph). Leakage in 2R26 spontaneously reduced to 0.02 gph approximately three days after pool flood. It is believed the initial leakage in 2R26 was the result of refueling cavity sandplug cover leakage that spontaneously decreased as the weight of the refueling water seated the cover. In 2R27 no significant leakage was indicated until 17 days after initial pool flood following a drain down and refill of the pool. It is believed the leakage developed at the segmented seal between the refueling pool floor and the reactor vessel as a result of changing pool level. Leakage has been experienced in previous outages on both units with documentation dating back to at least 1998. In addition to the RHR sump, past outages have shown leakage at other locations such as the regenerative heat exchanger room, nuclear instrument electrical penetrations and the floor near the reactor coolant drain tank.
- 2. An evaluation of the area, and the result of the evaluation.
As noted above, in December of 1998 Automated Engineering Services Corp (AES) performed an evaluation titled "Evaluation of the Effects of Borated Water Leaks on Concrete, Reinforcing Bars, and Carbon Steel Plate of the Containment Vessel". Following are pertinent excerpts from that evaluation. EFFECT OF BORATED WATER LEAKS ON CONCRETE Many studies have been conducted on the effect of acid rain on concrete. Laboratory studies have been conducted [Ref. 1,2] utilizing accelerated test program for effects of sulfuric acid solutions with pH ranging from 2 to 5 for periods ranging from 30 days to 100 days. Concrete samples with strengths varying from 3000 psi to 9000 psi were studied. The studies revealed the surface deterioration of the concrete increased as the
Inaccessible Areas Evaluation 50m55a(b)(2)(ix)(A) strengths increased due to the higher cement content in stronger concrete samples. It also increased with increasing acidity of the solution. However the corrosive effect of borated water (boric acid) is less than that of sulfuric acid at the same acidity levels. Reference 3 shows that boric acid has negligible effect on concrete whereas the same reference indicates that sulfuric acid will rapidly disintegrate concrete. Discussions with Portland Cement Association (Mr. Robert Shuldes) confirmed that the effect of borateg water will have negligible effects on concrete especially since the surface is wetted only for a short time duration (about 15 days every outage). The lack of deterioration of the concrete surfaces where white deposits were seen further reinforces the observation that borated water does not have any appreciable effect on concrete. Based on the above, we can safely conclude that the internal concrete surfaces at the construction joints and in the flow paths of the leaks would not have any deterioration. There is no safety significance of the borated water leaks on the concrete surfaces since the concrete structure would not have deteroriated and should be capable of performing its intended funciton. EFFECT OF BORATED WATER LEAKS ON REINFORCING BARS Since the borated water does not affect the concrete surface, the reinforcing bars would be fully protected inside the concrete. Note that the chloride content of the leaking water is small and will have no effect on the reinforcing bars. Also there is no evidence that the concrete surfaces have cracked thereby providing a path to the seepage of acidic water directly to the reinforcing bars. The likelyhood of any corrosion of the reinforcing bars in this situation is very remote. Based on this observation, there is no reason to suspect the corrosion of the reinforcing bars. Therefore, the strength of the reinforced concrete material is not compromised by the borated water leaks. EFFECT OF BORATED WATER LEAKS ON THE CONTAINMENT SHELL PLATE MATERIAL It is known in the nuclear industry that borated water in the form of boric acid can be corrosive to components fabricated from carbon and low alloy steels [Ref. 41. However, most of the studies conducted involved reactor coolant at high concentration (I 3,000-1 5,000 PPM of boron with small amounts of lithium) and at high temperatures (>200°F). Reference 4 concludes that the maximum corrosion rates occurred where moisture can be replenished by a flowing solution, keeping a wetldry interface between the solution and the dry boric acid crystals. It was also seen that when the boric acid dries out and is not significantly re-wetted, the corrosion levels are much lower.
Iilaccessible Areas Evaluation 50.55 a(b)(2)(ix)(A) As a precaution, NSP removed a portion of the grout material adhering to the steel plate around the pipe sleeve in the Sump B. The exposed steel surface did not show any signs of corrosion or surface pitting. This provides strong evidence that the boric acid solution was weak enough and was not constantly wetted for a long enough period of time to cause any deterioration of the steel plate surface. The same argument can be extended to other plate surfaces which are not exposed and which may be in the leak paths. Based on the above, it is believed that the containment shell is not affected by the observed leaks and has the capability to perform its intended fuction. The evaluation quoted above was reviewed by Automated Engineering Services Corp in December of 2006 in response to the leakage observed in 2R24. The review determined that the basis and conclusions developed in the earlier report were still valid and the integrity of the structural components (concrete, rebar and containment shell) was not compromised. An independent evaluation was performed by Dominion Engineering in March of 2009. The Dominion evaluation was consistent with the previous AES evaluations indicating minimal degradation. Following are the conclusions of that evaluation: o Because of the buffering effect of alkalinity from the concrete, the pH of the water in continuously wetted areas between the concrete and lower dome of the steel containment vessel is expected to have been in a range that inhibited corrosion of the steel, e.g., over about pH 12.5. As a result, it is expected that, as a best estimate, the maximum amount of corrosion that has actually been experienced in the wetted areas between the concrete and the inside surface of the steel containment vessel is insignificant, no more than a few mils (e.g., < 10 mils). While it seems unlikely, the possibility cannot be completely ruled out that the pH of the water in contact with the steel containment vessel could have been at the near neutral values that have been measured in Sump B. Analysis of this case, assuming continuous wetting of an aerated neutral pH region for the full 36 years of operation, leads to an upper limit estimate of about 0.25 inch of corrosion. It needs to be understood that this estimate is conservative since it is unlikely the pH has been at such a low level, and since it is unlikely that the aerated region at the water line has remained in the same area, such that the accumulated time duration of exposure at any one elevation is much less than 36 years. 0 Thinning of the upper limit amount of 0.25 inch poses no risk of leakage under normal or accident conditions since the wall thickness is 1.5 inches.
Iilaccessible Areas Evaluation 50.55a(b)(2)(ix)(A) Preliminary evaluation of the effects of thinning at the upper limit amount of 0.25 inch is that it will not result in excessive stresses or strains under accident conditions. This is a result of the bending stresses and hoop stresses in the possibly thinned area at the lower knuckle region of the steel containment vessel being essentially eliminated by the support provided by the reinforced concrete on both the ID and OD of the steel containment vessel in the knuckle region. Support for this conclusion is provided by limit load analyses of steel containment vessels that have shown that, even for steel containment vessels with 65% of wall loss for significant parts of their circumference (about 13 feet), the failure pressure is still over four times the accident design pressure (Table 2 in [22]). However, it needs to be understood that any actually detected thinned areas would need to be formally reviewed and accepted per Section XI of the ASME Code, and not per the above preliminary evaluation.
- 3. A description of necessary corrective actions.
The site has taken several actions to prevent leakage since 1998 including caulking refuel cavity leakage points prior to pool flood and the use of a spray-on strippable liner. In addition, a section of concrete was removed from the RHR sump the fall 2008 2R25 outage (W000327768) to allow direct visual inspeciton of the steel containment vessel to assure no significant degradation. In recent outages the site has seal welded suspected leakage points at the internals stands and Rod Control Cluster Change Fixtures of both units. The site has also excavated the reactor sumps of both units to allow direct examinaiton of the containment vessels and has extracted core samples of the refueling cavity floor of both units. The welded repairs have significantly reduced leakage on both units. The site continues to pursue complete leakage mitigation and continues to inspect for degradation. The site has made several commitments to mitigate leakage and monitor for degradation in conjunciton with the License Renewal process as listed in AR 01 16372. In summary, the site has a high level of confidence there is no significant degradation of the containment vessel or associated structures based on evaluation and examinaitons. The site continues to take actions to prevent future leakage and continues to perform examinations of the containment vessel to assure no significnat degradation.

SUMMARY
REPORT Section 6. Snubber Inselvice Testing and Preservice Examinations 1 page There were a total of 21 snubbers functionally tested in 2R27. All testing was completed satisfactorily. Seventeen of the twenty-one were Basic-PSA hydraulic snubbers, these snubbers had spares rebuilt and tested SAT prior to installation. The Basic-PSA snubbers that were renloved were tested in the as found coildition and all were also SAT. There was one ITT Grinnel snubber that was tested SAT and re-installed. One Paul Monroe snubber was functionally tested SAT and re-installed. Finally two steam generator valve bloclcs were replaced wit11 re-built spares, all pre-install testing of the rebuilt and the as found testing of removed valve blocks was SAT. There was no scope expansion due to failed testing of the sainple population during 2R27. Some of the testing was perfoimed by a Basic-PSA field represeiltative, with most tests performed by in-house maintenance after Basic-PSA field rep depai-ture (due to outage expansion). The visual inspections for SP 2171 and TP 2535 were performed by LMT. There was no scope expaiisions due to conditions found on these inspections. The snubbers that were inaccessible were not inspected. All cylinders had hydraulic fluid and any deficiei~cies noted during the visual inspections were inspected by the Snubber Engineer. Six Action Requests were initiated as a result of visual inspection deficiencies and those action requests were resolved prior to leaving Mode 4. Any leakage identified was attiibuted to fluid from overfull reservoirs and thernlal movement. Those snubbers identified during the inspections with no move~l~ent or rotation, were inspected by the snubber engineer and those that were accessible, rotation and movement was evaluated and no snubbers were found to be loclted up.
