REGULATORY GUIDE DISTRIBUTION LIST (DIVISION 1)

SUBJECT: WITHDRAWAL OF SIX DIVISION 1 REGULATORY GUIDES

The following regulatory gutdes were issued as fnd1cated to provide guidance to licensees and applicants for tmplementfng portions of the Corrmfssfon's regulations with regard to materials, construction, and testing of concrete containments and other safety-related concrete structures:

1.10 "Meehanical (Cadweld) Splices fn Reinforcing Bars of Category 1 Concrete StructurH, 11 Revfsfon 1, January 1973,

1. 1 S "Test1 ng of Reinforctng Bars for Category I Coricrete Structures, 11

Revfston 1, December 1972,

1.18 "Structural Acceptance Test for Concrete Pr.1mary Reactor Containments , 11

Revision 1, December 1972,

1.19 "l'{ondestructfve Examination of Primary Containment L 1ner Welds," Rev1s1on 1, August 1972 (Safety Gutde 19),

1.55 "Concrete Placement fn Category I Structures," June 1973, and

1.103 "Post-tensfoned Prestressing Systems for Concrete Reactor Vessels and Containments, 11 Revision 1, October 1976.

The regulatory positions of these guides are now considered to be covered ·by one or more of the following national standards:

ACI 359 (ASME Section III, D1v1sfon 2), "Code for Concrete Reactor Vessels and Containments," endorsed by Regulatory Gu1deJ.136, "Materials, Construction, awd Testf ng of Concrete Containments (Articles CC-1000, -2000, and -4000 through ·6000 of the Code for Concrete Reactor Vessels and Containments}.~

ACI 349, "Code Requirements for Nuclear Safety-Related Concrete Structures9" endorsed by Regulatory Guide 1.142, "Safety-Related Concrete Structures for Nuclear Power Plants {Other than Reactor . Vessols and Containments)."

ANSI N4S.2.S, "Supplementary Quality Assurance Requirenents fo Installation, Inspectfon, and Testing of Structural Concrete, Structural Steel, Sofls, and Foundations During the Constructfon Phase of Nuclear Power Plants," endorsed by Regulatory Guide T .94, 11Qual1ty Assurance Requirements for Installation, Inspection, and

Testing of Structural Concrete and Structural Steel During the Construction Phase of Nuclear Power Plants."

Therefore, Regulatory Guides 1.10, 1.15, 1.18, 1. 19, 1.55, and 1.103 are being withdrawn. Withdrawal of these guides 1s fn no way intended to alter any prior or existing licensing ca111111tments based on thefr use.

Regulatory guides may be withdrawn when .they are superseded by the Conmfssion's regulations, when equivalent reco111nendatfons have been incorporated fn applicable approved codes and standards, or when changes in methods and techniques or in the need for specff1c gu.idance have made them obsolete. · ·

Tht 1ven1e stren1th o( a destsn mix. based on mean rather than maximum allowable values of air content and 'liump is not conservative relative to standard buildin1 con· muction practice. The limits in Re111acory Poiition C.1 are taken from Section 4.4.2 or ACI Standard 318-77, ''Bwldinl Code Requinmenu for ReinCozced Concrete.,,,

l. CC·2143 • Cement Grout for Grouted Tendon Sntema

Re111l1tory Position C. l recommends llsllll the 111idance iD Re111J.ttory Guide 1.1<17, ''Qualification for Cement Grout· inl for Prestnuinl Tendons in Containment Strucnires," rather th:an parqnpb cc.nu with respect to sroutin1 of presuessina iendons.

Subparacr:aph CC·2441(t) addresses only me susc:eptibil· ity of ducts to leaka1e under pressure. However, duct joints ue more susceptible to leaka11 under pressure than rhe ducts. Th• recommended prtqualllication of ducu and duct joints in Resulatory Position C.5 would eliminate 1h1 potential for peue (or srout) lealcap undor maxim11m preuures.

6. CC·246U ·Sutic Tensile Tat

DUferent systems of presuesain1 may require different numbers ot tests for tendon systems to est;;;bliJh their adequacy for use. Variations within the tolerance limits or the construction specification in material properties and in 1eome try oi am:horaaes Uld tendons muse be realistic:slly md adequately represented in the system testina. Therefore, Re111latory Position C.6 recommends that :my system of presmssina be Nbjected to a sufficient number of tests to establish its adequzcy before it is adopted Cor use.

7. CC ... 240 • C11rin1

The 1980 version of the Code eliminates a specific requirement Cor curin1 concrete at temperatures hi&her than 40° F. The suide recommendation is in accordance with ACI 308·71, "Recommended Practice for Curin1 Concrete. ,,J

VALUE/IMPACT STATEMENT

This Revision 2 to Reaulatory Guide 1.136 ptovides informadon re1ardini the NR.C srafrs positions on the acceptability tor NRC licmnlina ac:tions ol Anicles CC· l 000, -:000, ·4000, ·5000, and ·6000 of the ''Code for Concrete lltmctor Vessels and Containments"• published joindY by the American Society or Mechanic:al Enpeers (ASME Boiler and Pressure Vessel Code, Stction Ill, DiYision 2, 1980 Edition) and the American Concrete Institute (A.Cl Standard 359-80). In those areas where the NllC naff finds pro./isions of the referenced Code insufficient for licenslna purposes, supplementary suldeliDes ue aiYen in the reaula-tory position. ·

Foilowin1 Issue of Revision 2, this suide will be periodi­cally updated to st:iy cur.nnt with the ASME Codi, Sec­tion Ill, Division 2. Thb will be done under pt0eedur11 similar to those under which Reaulatory Guides 1.84 and 1.85 are updated in the endorsement of ASME Code Cues. ·

Value

Issuance and implementaiion of llUI 111ide will provide the NRC reviewers and applicants a common bUis for understmdina the Code Rquirements for materials. consuuc· tion. and testinl of con1:r11te containments, thus minimWnl potential subjective interpretations on the deareo of acctpt· ability for materials, construction, and t11tin1 of concnte containments.

lmpacr

Mose Code roquiremcsnts an now beini accepted by the industry and NRC. Therefore, the endorsement of tl!.1so Code requirements would have no additional impact on in1ustry.

The value/impact of positions of this revision to the pidc are discussed below:

R11ulacory Positions C. l, C. 7, C. J 0, and C.11 should have no appl'9Ciable impact on rhe induscry or the public since they recommend acnerally accepted constiuction practice.

ReplaCOry Polition C.2 recommends che use of che more detailed recommendations of Reirulacory Ciuide 1.107, · which include a reference co the exiscin1 Code requirements of CC·2:Z43 where appropriate. The value/imp:icc and rationale for rtcommendatiom in Reaulatory Ouide I. I 07 have been tboroushly discussed in the resolution or public comments on that suide and durina the public meedna in November 1'976.

Reautarory Po-~11ons C.3, C.4, C.S, and C.10 empbuize the need to pr-~quallfy prestressin1 system components by adequate testins. Th•• positions ue consistent with th• way tho prntoualy approved presueain1 system· com· ponents were required to be qualified. The NRC staff believes that th• Code lacks the91 specific requiiements. They would help ensure the safecy and intelP'itY of the quallfled prestreuinl sysiem durin1 the useful lift of the conu.inment. Their impact on the industry should be minimal. .

Repllatory Positions C.6 and C.iJ remlin essentially uncban1ed from t111 Savember 1979 issue of this auide for public comment.

Replatory Position C.9 represents an editorl.31 correction to eliminate a conuadiction ill the 1980 edition of tbe Code.

Rquiatory Position c. l :? has been revised to reflect public commenca m:eived and to fulfill a need without any neaatiYe impac:t on the industry.

Recommendatiou

Revision 2 oi tho auide should be itsued for 1"1plementa· tion u described in Section D, "Implementation." of the pide.

All complete<! mect-.aniC31 splices sho~lc! be inspected 3t both ends of the splice and al the rap nok i.i t.i' center of the splice sleeve in accordmce with !he reqt.:uement: specilled by the designer of the structure and ·ifJProved by the licemee. All Yisll!! lmpections on .:om?l-:1ed splices should be performed only after rh: splices have cooled ro ambient temperatures.

Among the i!ems which mould be included in the spec:tficaUons at'!! longitudinal t"!nter.rig of sleeve on the spliced ends. ~In filler m:ul. extent of leaking of riller mel3', permisslbie g:ip be~wten rebar ends. cartidge size, ps blowcut, amoun: of packing and slag at the tap hole. Splices :hat f.lil to pass Visual inspect.ton should be dil4'3J'ded l!ld l"?place;i, and shou!d nor be used u tensile test samples.

3. Temile Tesdor. Splice tamples may be production splices (i.e •• those cut direct1y from in·place reinfor~gl or sister splices u.e.. those rei:!~vabl~ splices made in-place next to production splices :me! under the same conditions).

Si.nee curved reinforcing bzrs ·.vlll not tensile test ac:::ur:uely, production splice samples should not he removed from curved rei.'1forcing bars for tensile te::ting. Straight sister spUce samples .should be made :is testinl! substitutes for each of the rec;mred c:u:ved reirJorcmg bar production Sl'lic:es. The samrifing fr~quency spe~iied in paragraph 4b. should then be followed.

Production splice samples should nor be cut irom the suucrure where the mechanical splicing sleeve is shop wel!led .10 an anchor.age in a region of high su~s concen1ralion. and/or at :1 leak-tighr barrier (e.g., embedded structural nee I sect1om or liner ptare J, Representative sisrer splice samples should be used in
