, EVALUATION - BRAIDWOOD The concerns expressed by Len McGregor in his evaluation were first identi-fied by hit in January / February 1983. At my request he prepared a memo dated February 22, 1983, outlining his findings and attached the supporting -
documentation. This package was then sent.to the Engineering Division (Duane Danielsonk Section) for followup and resolution. The assistance request fore dated February 22, 1983, basically asked Engineering to address three issues (McGregors concerns). These werei
. Eas all the small bore piping that does not meet minimum code requirement for wall thickness been identified and removed?
Was a review conducted by S&L and if so was that review adequate relative to the use of about 4000-feet of small bore piping in Class I systems when it was known the piping did not fully meet all ASM1 Class I code requirements? '
. War sieflar piping purchased and used at byron?
Engineerin; has conducted inspection relative to these issues and as I understand the last twe are resolved. The first remains open pending further action by the licensee and will be addressed in the enforcement conferer.cc scheduled for December 20, 1983. The tracking number is 4 56 / D-M-031. 1 _ _ _ c=

l Engineering has discussed their findings with Mr. McGregor and he concurr that his concerns have been addressed. I view of this and the fact the unresolved-issue is being separately tracked this' iter (No. 'F03043583) ~ should be closed on the manager.ent tracking systet.

Applicable requ2rements related tc the MRhs listed above were performed in accorcance with applicable QA requirements. Ne apparent items of noncompliance were identif2ed.
- 1. Site Storage Facilities Tne inspector, accompanied by CECO and PGCo personnel, conducted a tour of Warehouse Sc. 5 assigned to Phillips-Getschow f or the storage of j safety relate: mechanical material.
The warehouse was inspected to determine the environmental storage conditions , control of access to storage areas, cleanliness and house-keeping, identification of stored items, and compliance with storage requirements specified in ANSI N45.2.2, Section 6.1.2, levels of storage, Section 6.1, storage areas, and Section 6.3, storage methods. Tne following findings were observed: -
- 6. During an inspection tour of the CECO site Storage Warehouse No. 5 assigned to PGCo, an interview with the PGCo warehousemer.,
including supervisors, revealed that No system exists to monitor, and control the temperature in warehouse No. 3 to prevent con-densate and corrosion by maintaining a temperature band of 40*T - to 140*T as required for facilities housing Level E items. Additionally it was also determined through interv2ews with the warehousemer. that NO syster exists to monitor and control humidity as required for items which may be stored in warehouse No. 3, which is qualified by CECO, to Level A material. Tailure to provice adequate systems to monitor and control temperature and hu:2dity is considered to be a violation of 10 CTR 50, Appendix I, Cr2terion XII: and ANSI N45.2.2-1972 and is considered to be an itet of noncompliance as described in the Appendix to the report i transtit:El letter (456/82-07-Ola, 457/82-07-01a.) .

Trie warehousemar. reported that pes: contro; of rocents serv 2cc by extereinatso: was provided ey the Ork:r. Ex:ert:nating Company by contract or. e regular bas 2s. Evicence cf this serv 2ce was verified by toe presence of cumerous packages of becer. and other basts coservec throughout toe warenoust Animal entrance was determined, however, by the pre.sence of anima; feces in a number of areas of the storage bins. Additionally the inspector noted a number of missing foundation to wall fillers and holes rippec or torn an the warehouse walls which would allow un-controlled and unlizited access to a variety of small animal species. Failure to implement and maintain adequate measures to prevent the entrance of animals is considered to be e violatior. of 10 CFE 50, Appendix E, Criterion XIII and ANSI N45.2.2-1972 and 25 considered to be an 2 tee of noncompliance as described it. the Appendix te the report transmittal letter (456/82-07-01c; 457/82-07-01c). -
- d. In one area of the PGCo Varehouse, the inspector attempted to gair: access to portions of the DRPI assemblies and MRE 2626 crates f or the purpose of verifying ready access for the periodic inspec-tions specified. Due to the methods of arrangement and stacking in this area, the attempted acces's proved futile. In this con-figurat2on routine inspections cannot be performed without excessive handling which would increase the risk of damage. Failure to provide ready access to stored items for periodic inspections is considered te be a violation of 10 CTE 50, Appendix E, Criterson XIII and ANSI N45.2.2-1972 and is considered to be an itet of noncompliance as described in the Appendix to the report transmittal letter (456/82-07-01d; 457/82-07-01d).
- c. In the northwest corner of Warehouse No. 3, the inspector observed a wooden pallet upon which were piled approximately five or six what appeared to be pneumatic operated valves. In addition to the valves . their were approximately six valve reach rod assemblies and a quantity of small diameter wire. hone of these items bort the appropriate required identification markings. It was also noted that none of these items were packaged for storage or had sealing closures installed. This failure to control inadecuately doentified co:ponents ir, storage is considered to be a violatio:.
of 10 CFr SC. Appendix E, Criterion XIII and ANS: N45.2.2-197; and is considered te be en itee of nonco v11ance as described it. the appendi> to the report transeittal icttcr (456/f:-07-Ic; 47, t;-C T-h

- g. During the tour of karehouse Nc. 3, the inspector inquired as to how the access tc the storage area of Warehouse No. 3 was controlled and limited only to personnel oesignated by PGCo. It was reported tha the warehouseman maintained surveillance in the storage area and ensured access control. Tne inspector noted, however, that during the tour of karehouse Nc. 5 none of the inspecting party was challenged by the warehouseman nor were any members requested to sign ar. access log or any other fore of access control documentation.
At the conclusion of the inspection tour of Warehouse No. 3 the inspector requested the CECO QA depa 6 ment to provide personnel access to storage area records for Warehouse No. 3 for review. CECc QA personnel reported that no personnel access to storage records were maintained and therefore none were available for rev2ew. This failure to prepare personnel access to storage area records is considered to be a violation of 10 CFR 50, Appendix E, Criterion XIII and ANSI N45.2.2-1972 and is considered to be an 2ter of noncomp12ance as described in,the appendix to the report transt2ttel letter (456/82-07-lg; 457/82-07-lg) . Plant Tour The inspector walked through various areas of Units 1 and 2 to observe operations and activities in progress, to inspect the general state of cleanliness, housekeeping and adherence to fire protection rules. Ne apparent ite=s of noncompliance or deviations were observed. Exit heet2nr The inspector met with licensee representatives (denoted under Persons Contacted) et the cenclusion of the inspection on December 17, 1982.

50-456 AND 50-457 (BRAIDWOOD) a This is te notify you of our intention to close an unresolveE iter in I Region III Inspection Report No. 50-456/76-06; 50-457/75-06 regarding l total chleride ion content in concrete at Eraidwood. Tne issue was first brought te IE's attention in a memorandue dated July 11, 197E, Spessard , te Reinmuth. Which is included as Attachment 1. Even though no written ' response to our request has ever been received, there has been consider-l' able effort expended by Region III and both the IE and hTJ staffs on this issuc. One cf those efforts was a presentation to th's Region III staff by Co :::nwealth Edison on February 17,19E3. Tne documentation of that pre-sentation, dated April 10, 1954, is included as Attach ent 2. We have i re-evaluated this issue, and based on the technical cerit of the information previded by the licensee and'our past discussions with representatives frc: h7J., we believe that this issue has been satisfactorily addressed. Tnereferc, our original request (delineated in Attachment 1) is no longcr j apprepristc, and we plan to close this unresolved iter in a future RIII 4 inspe: tion repert. l Flease contact te if you or your staff have any questions or cor:nents i regarftng thts catter.

Chloride Content in Concrete ACI Committee 201 (" Guide to Durable Concrete" ACI-201.2R-77, American Concrete Institute, 1977) has recommended, and ACI-318 and ACI-301 have adopted, a lower bound limit on chloride content
- of 0.06% by weight of cement, for prestressed concrete. This value is based on the premise that the prestressing steel is in direct contact with the concrete. The prestressing steel
; at Braidwood is contained in sheathing filled with grease for i
corrosion protection, and therefore, the 0.06% limit is not appla-cable. The ACI-201 limit for conesete exposed to chloride in service is 0.104. However, based on current inf ormation, ACI-316-E3 has adopted a 0.15% limit for concrete exposed to chloride in service. As stated in Section 4.5.( of the commentary, 'The more liberal limits were developed after consultation with ACI l Committee 201 on durability and 222 on corrosion, and are con-sidered to represent the best information available at the time of adoption". The 0.15% limit on chlorides in concrete is most applicable to Braidwood. The 0.15% limit for concrete exposed to chlorides is conserva-tive since it is intended for the worst exposure normally expec- ' ted (bridge decks or seawater exposure) where the chloride ion

of the groundwater at Braidwood is less than 350 ppm. ; l It should also be noted that the ACI limit is on water soluble chlorides. 1 Due to the difficulty in determining the amount of i chlorides which are water soluble, the total amount of chlorides present are compared to these limits. Also, some of the chlor-ider which are initially water coluble are chemically ecmbined with the hydrated cement, further reducing the chlorides avail- : i able to induce corrosion.

For admixtures, the maximum amount of chlori'de allowed by Specification F/L-2722, 14 by weight, was used whereas the actual amount determined by tests did not exceed 0.15%.

As shown in Table 1, the upper bound limit on the ratio of chlor , ide content to cement is 0.0274. This is f ar belot the ACI limit of 0.151 for reinf orced concrete exposed to chlorides and even well below the 0.06% limit for prestressed concrete. The limit of 500 ppm on chloride ion in the mixing water found in Specification F/L-2722 provides control on the largest contri-butor to the total chloride content in the concrete. The AF'I 1977 edition provided for a limit of 250 ppm for water but haJ no limit on the total chloride content. in the concrete. In *.he 1980 edition summer 1980 addenda, the limit on chloride content in water ide was deleted and replaced by a limit of 400 ppm on chlor-content in the cement paste. As shown in Table 1, the chlor-ide content, using the name conservative assumptions, is 104 ppm. The specification limit on chlorides in water of 500 ppm has limited total chlorides in concrete to acceptable levelt. Iron oxide Deposits on Tendon Tunnel Walls Mr. Gallagher, after his inspection of the tendon tunnels, noted "the apparent effects of groundwater in the form of corrosion of the embedded steel (reinforcing) and by the presence of depo-sits of iron oxide on the walls of the tendon gallery", where groundwater was leaking through cracks in the walls. On August 22, 1980, a Level III ASME/ACI Nuclear Engineer Inspec-tor, examined areas in the tendon tunnel. Where the concrete was cracked and iron oxide deposite were present, concrete was removed for approximately 4 inches behind the interior face rein-forcing cteel. Examination of these areas yielded no evidence of corrosion on the reinforcing steel. In addition, no discolor-ation of concrete was found at the exposed crack approximately 4 inches behind the reinforcing cteel, thur discounting the poten-tini for corrosion of. reinforcing tteel at the exterior face of the tendon tunnel.
l Furth2rmore, during tne inspection, it was determined tnat a
' waterproofing system using metallic grout was used to repair cracks. Tne reddish-crown deposits occurred only at the repaired j cracks with the rust confined to areas containing tne metallic i
grout. To minimize f uture groundwater leakage into the tendon j tunnels, these cracks have been repaired using a concrete water-i proofing' system acceptable f or saf ety related work and whier. does not contain a metallic grout. t i

Mr. Carrera discussed S&L's understanding and disposition of the chloride p robles. Mr. McCregor presented the history of the chloride problem and background of Ceco's commitments to various codes and standards. Mr. Williams spoke for the NRC. It was concluded by the NRC members that S&L had adequate information to support their disposition of accepting the concrete 8as is"; however, S&L was requested to formally submit the infor-nation to RIII for their review. NRC requested that the upper limit of chlorides be included in the submittal. 0 s i. 4 a.. % .'.,. w Frank J. Jationski Acting Chief Frejects Section 18 cc: t. Williams R.. Knop
