Separation'of Electrical Equipment i
Plant Wide Field Audit ,
Procedure
.l. Scope 1.1. Perform a detailed field audit to verify that the instalied e lectric equipment and systems conform to the separation criteria ' described _ in the La Salle Final Safety Analysis Report 1 (FG AR) , subsecticas 3.3.1.3 and 8.3.1.4 as projected in Electrical Work Specification J-2559'. The audit shall include.a sample of not less ' than 10% of the ins talled ,
Safety-Related equipment. and cables.
2.- General ,
- 2. l' The audit shall be conducted by a Separation Task Force Audit Team -(Task Force) consis ting of an engineer Task Ieader with supporting engineering and technical personnel e designated.by Sargent & Lundy and the owner, who are familiar with separation criteria, standards and guides as ,
- they apply to the La Salle County Station electrical equip-ment and. systems. No member of the Task Force shall have
, participated' in the design and ins tallation of any equip-
, ment dnd systems subject to this audit.
I i

The existing onsite Commonwealth Edison Construction Offices shall be used by the Task Force for an audit control center. (Telephone 2.3 The Owner shall designate a participating staf f (Ceco) Task Force member as Safety Coordinator to perform liaison func-
- - tions between Ocerations/ Construction forces and the Task
-l Jerce. The' Safety Coordinator shall arrange for tags or
' clearances, when required,ifor access to energized circuits,.
!.f elactrical equipment, panels, enciesures, switchgear and mo?.or control centers. In addition, Jua shall arrange for scaffelding, ladders or other items required to visually <in-spect cable trays or enclosures which are not readily acces-sible.
2.4 The audit shall include samples of (but not limited to) the
't following' general categories:
q L: a. Separation of redundant Class 1E equipment.

2.4.1 The audit will include 1a review of conduit and conduit sup-ports, cable tray and cable tray supports, cable in conduit and trays, cable at control ~ boards, and control board wiring for portions of those systems listed in Table 1. g 2 . 4 .' 2 . The specific equipment and systems to be audited are shown on Separation Audit Forms and Cable Tabs which are listed '
in Table 2.
(
2.4.3 Separation violations discovered during the audit of equip-ment and systems which do not appear in Table 2 shall be
+ i documented on additional Separation Audit Forms. Miscel-s laneous items will be listed in Table 2A and will form an s,
integral part of this audit.
- 3. Agdit Criteria 3.1 The safety evaluation report for La Salle County Station con-struction permit was issued on September 10, 1973. Since Regulatory Guide (RG) 1.75 (Rev. 1) " Physical Independence of Electrical Systems" applies to plants whose safety eval-uation report was issued af ter February 1, 1974, compliance with RG 1.75 shall be in accordance with LSCS FSAR Appendix '
3, Amendment 43, Page B.194.
3.2 Independence of redundant Class 1E systems and equipment shall be installed to ensure availability during any design- .
basis event as described in FSAR subsection 8. 3.1.4 l
" Physical Independence of Redundant Systems ," 8.3.1.4.2.2
" Cable Routing Criteria" and 8. 3.1. 3 " Physical Identification of Safety-Rele ad Equipment." These criteria are transmitted :
to the field by the La Salle Electrical Installation Work l Specification J-2559, Amendment 2, dated December 13, 1978. ,
1 3.3 Cable fire protection shall comply with FSAR subsections I 8.3.3.2, 8.3.3.3, 8. 3.1. 4. 2 and FS AR Appendix H , Fire :czards Analysis.

- 3. Audit Criteria (Cont'd) 3.4 The criteria referred to in paragraphs 3.2 and 3.3 (above) shall be the basis for performing this audit.
- 4. Systems Selected for Audit 4.1 The audit shall be performed on sample portions of systems
- and related electric equipment as shown in Tab 1? 2. The approximate total number of Class lE cables ins talled for
, each system and those to be audited are also included.
4.2 The cables selected represent a variety of physical loca-tions; i.e., the AP system represents portions of various s switchgear and motor control centers, DG represents cables related to each diesel generator, etc.
- 5. Audit Procedure 5.1 The Task Force shall review those cables, raceways and equipment listed in Table 2, to verify that the Installer nas properly implemented the design referred to in para-graphs 3.2 and 3.3.
i 5.2 The Task- Force auditor shall visually verify that cable routing, raceway separation, control panels and boards, terminations, barriers, isolation devices and equipment
- identification do not present deficiencies that, under 4 single failure conditions, could result in the simulta-s neous loss of redundant safety-related equipment with pos-sible subsequent less of safety function. Any violation of the separation criteria shall be considered as a defi-ciency.
5.3 Field audit forms listed in Table 2, shall be used with l the respective Cable Tab, for recording data.
5.4 Those criteria listed in paragraphs 3.2 and 3.3 are assigned identification numbers for use in this audit as shcwn in Table 3. The Task Force shall become familiar with contents 'and numbering system assigned to various separation criteria described.
- 6. Separation, Identification and Fire Barrier Requirements 6.1 Separation, identification and fire barrier requirements referred to in Table 3 shall be used by the Task Force to
- record deficient or acceptance items for those cables in-cluded on the Audit Forms.

Finding #1 (Question.#2):
Contrary to the LaSalle County FSAR 24% of the 3"" Class IE cablen u:
equipment audited were improperly marked.

(b) stated cable was not tagged above equipment (11) ( 2. 7'E >
?CD's response to each of the above categories is as follovs:
v Category A.1: Discussion with the auditors :odicated tbnr th specific problem in this catoimry was that the segregation tags were not phy *cally ..t the
- .y piece of equipment. That is, i nc segrm.itiou ? -
N was at the end of the ritid c duit but not at the equipment end of the flexi' i e conduit ..hico
W :
1 - l connects the rigid condui t to the equipment.
l f- Project Construction is cuite aware of this practice J and does not consider it a separation " violation" j because the flexible conduit is limited to 18" l minimum and 6' ma:imum. This interpretation was d agreed to by both S:30'and S&L in a meeting on j I
October 21, 1980. i e Category A.2:
This item involves segregation tanc that were broken i off or missing. H. P. Foley (HPF) 'dork Instructions j
301 and 302 requires that these tags are installed i and this is verified by HPF QC on checklists HPFCo-028 {
and 030. There are numerous reasens why these tags J' j
c could have been knocked off after the conduit was l installed. Therefore, the area walkdown pi;ocedure which is being generated by Project Construction and I HPF contains a check for missing negregation t?gs. I Because a missing segregation tag is easily identified, Project Construction caels that tha area walkdo'n procedure is the correct mechanism to repiece any of these missing tags.
lc Cctegory A.3 and A.4:
These items involve one conduit which had two segregation tags and one conduit ihich had the vrong.
3 color tag. There is no evident renson why this was not identified during HPF's QC inst 2ctions. The ars-walkdown procedure indicated above requircr; another
! review of these tats and should be a sufficient cent en1 to correct the low percentage of this type of
~
l' misidentifications.
.Catecorv B.1:
This item concerned cable tags which were not legibn.
Because of the low percentage identified as illegible f
during the audit and the fact that a cabin's number can be verified by drawing referente, this itam is not considered significant. Field cables are and will continue to be re-tagged whenever it is identified that they require it. The audit results support that no additional action in this area is s.arranted.
Category B.2.a and B.2.b:
This item involves cables that were incorrectly tagted either by number transposition or urong color tags.
times the correct number is evident, for examnle, Many Unit #1 instead of Unit #2 or "IS" instead of "SI".
HPF WI400, Cable Pulling, requires that cables are marked and this is verified by HPF QC.
s
~
5 M Category B.2.n and B.2.b con't:
- As' in Category E. i, Project Constructi.on feels that the very low percentage of cables Cound incorractly marked indicates that this work lustruction is providing a realistically acceptable control in this.
area.
htegory B.3:
This item involven cables not beinr labeled inside of a aanel or JB. HPF WI500, Cable Tecminations, requires caale to be identified inside of a panel and this is verified by HPFCo. QC. In addition, UIS00 also requires that the cable is identified above a panel which is not a requirement in the LaSaTJ.e ES AR. This midit i.onal marking was added to aid the termi. nation crews and or inspectors. Many of the cables not identified inside ;
the panel were indeed, identified just above the panet.
This fact and the very low percentqe found not mot +.. i .
indicates that no additional action i.s warranted.
.stegory B.4:
This item involves a cable being mnrked tuice. It ir very similar to Categories B.2 and B.3 in that the H L '"
controls (UI400 and 300) are the scme. Only onn er.m: Le 1 of this does not warrant any additional action, besi Ws one of the markers was correct.
9 i
Category B.5:
As stated in S&L Letter 659 dated :10/31/80 (copy l attached), thirteen safety-related cables should not !
have been found unacceptable by the audit team. This l was a misinterpretation of the La.Srile identification criteria and these cables do meet the requiremeats of the LaSalle FSAR. (For Item B 3.b. ploase note tha:. the tagging of cables above a panel is a requirement of UF eb WIa00, but baccuse these cables we re 'dcutified in,)
panel, the LaSalle FSAR cable identi'fication criteria was not violated.)
i Corrective Action and Date of Full Comollance:
1 The field is correcting the occific listed in Attachment 2. The stacus o, is is " complete as indicated on the attachec .py. .a > lkdo m mentioned above will be conducted on a schedule which is commensurate with the scheduled area turnover to the LaSalle Operating Department. As sho.tn above.
it is Project Construction's opin4nn that no further action than this is justified.

W Follow Up Action:
Category: A1 - T. E. Matts letter dated December 23, 1980 to T. E. Qucha (sce attached) concurr with Pro' ject Contruction that the segregation tag at the end of the ri,gid conduit instead of the equipment and of the fic::ible conduit, uas a legitimate and acceptable methcd of tagging the conduit.
Categories A2', A3 & A4 -
Foley Procedure SCP-15 (f.rca Walhdown) is currently beine impicmented at LaSalle. Th- procedure specificaU-requ[res an c::cminction veri"yirc the cable end !

In the T. E. '.latts letter dated D .ccmber 23, 1980, Project Encincaring agreed wl.tb P oject "onstructinn ,
1 that the walkdoun insnection uill be an eEEoctivo 1 means of identifying and correc ti ig taggi.ng ocfic iencim on an arca basis, rather than tryLng to repnir or l replace cach tag individually. l Category 31 - In reference to the T. E. Watts 1.tter dntod December 23, 1980, Project Engin~. ring agreed uith Projee.t Construction that illegibl.e identification ' cans on cabia is not a major problem. The basis for their decision was that there was a le percentagn idone e n .1

For appro::imately the past two y ars Foley trork instruction WI-400 has required o.C. verific ation of the cable ta; identifications for all safoty rel: ted cables. It.is quite possibi.e tbo; the s:"n L J pe r"co r +

g 4-Project Construction response to each category is as follows:
Category C.l._1: Discussion with the auditors indicated that the specific proolem- in this category was that the segregation tags were not physically at the piece o f equipment. Thut-is, the seg-regation tag was at the end of tl.e rigid conduit but not at the equipment end of the flexible conduit which connec ts the rigid conduit to the' equipment.
Project Construction is quite aware of this practice and does not consider it a separation " violation" because Ute flexible conduit is limited to 18" minimu:a and 6' caximum. This interpretation was agreed to by both SNED and 3&L in a meeting en October 21, 1980.
Catego ry C.l.b: This item involves associated segregation tags tnat nave a Jolid white background instead of a :dciped background.
All of -the associated conduit segregation tags purchased for LaSalle have a white background and are stamped vtth a number to indicate the division association. This type of tag hon been accepted by Project Constru: tion, QA and the NRC for many years. However, in a meeting on October 21, 1980 3UED and S&L recommended that a striped tape be added in addition to the white metal tag to further indicate the division association.
The striped tape for each of the three associated divisions has been ordered and will be added to the conduite when it is
, II received. This additional taping will be verified during the aren walkdovns mentioned in Finding #1.
. Category C.2:
This item involves segregation tags that were broken off or missing. H.P. Feley (HPF, h'ork Instructions 301 r.nd 302 requires that these tags are installed and this is verifle l by HPF GC on checklists EFFCo-020 and 030. There are numerous reasons why these tags could have been knocked off after the conduit w:is installec. Therefore, the area walkdown procedure which is being generated by Project Construction and HPF containa a chect'. for missing segregation tags. Eacause a missing segregation tag is easily identified, Proj?ct Construction feels that the araa walkdown pro:ecure is the correct mechanism to replace any of these missing tags.
Category C.3:
These items involve one conduit which had two sedregation tags and- one conduit which had the wrong color tag. Ibare is no evident reason why this was not identified during KPF's CC inspections. The area walkdown procedure indicated above requires another review of these tags and should Pa a suzIicient control to correct the low percentage of this typ' of mic Ldonti-
~~T fications.

Catego ry C.4: l 7} l This involves an associated (lix) cable TheIVX052 ceditor which wasthe indiented routed !
in a conduit with Div. 1 cables.
j i This is incorrect; the conduit r.hould have been marked 13 K. l conduit is and should be marked liK. This was confirced in S&L's letter 653 dated 10-31-80, page 2.
Category C.5:
This involves seven junction boxes which were idW Lfied during the coloraudit as notmarker permanent having(a permanent one). HPF has marker (six) started just recenriy or had the wrong tag is to put on junction box covers (normally where the permanent p15ced) because the cable pulling in Unit #1 is nearly comple te.
This is another item on the area walkdown checklieb that will )
be verified during the walkdowns. !
Catecorv D.1:
Because This item concerned cable tags which were not legible.
of the low cercentage identified as illegible durtng the audit and the fact that a cable's number can be verified oy drawing reference, this item is not considered significant. Field cables are and will continue to be re-tagged whenever it is identified that they require it.
The audit results support that no additional
. . ,3 actica in this area is warranted.
lL' Category D 2a cr.d D.2b: l I l As stated for Category B.2.a, the low percentage of cable tags having number transpositions and the fact that cable numbers can be readily verified by drawing or cable tab relerence, l
indicates that no further control in this area is required.
Item D.2.b involves cable tags which are the wrong :olor.
PCD feels that the primary purpose of the color coded cableOnce tag is to verify cable segregation during cable p nling.
the cable is installed, there is no cafety significince to the cable tcg color coding. It is Project Constructirn's positico that the Audit results inqicate that this color emie marking -
is being controlled within acceptable limits.
Cate co rv D. :a :
This item involves cables not being labeled inside of a panel or J3. HPF WI500, Cable Terminations, requires enele to ha identified inside of a panel and this is verified by HPFCo. CC.
In additier., b'I 5CO 31co requires that the cable ir identified above a panel which is not a requirement in the LaSalle FSAR.
This additional marking was added to aid the termination crews and CC inspectors. Many of the cables not identifiedThis inside fact the panel vore indeed, identified just above the panet.
J and the very low percentage found not marked indientes tha t l
no adcitional action is warranted.

,g Category D.3b:
This item involved associated cables which were marked with one piece of white tape and one piece of colored tape instead of the normal striped marker. Thi.o was done by HPF Production cn a temporary basis because they ran out of associate J markers. This was written up by HPF QC on a Cor.ective Action Report. This controlled document will be required to be closed Jut prior to Project Construction turning over the particular areas to LaSalle Operating. It is Project Construction's opinion that this hos been and will be the best method to control the remarking and assure its completion.
Cateeorv D.h:
This itas involves a cable being marked twice. It is very similar to Categories 3.2 and 3.3 in that the HPF controls (WI 400 and 500) are the sane. Only one examole of this does not warrant any additional action, besides one of the markers was correct.
Categorv D.5a & D.5b:
As stated in S&L Letter 659 dated 10-31-80 (copy attached),
thirteen safety related cables should not have been found unacceptable by the audit team. This was a misinterpretation of the LaSalle identification criteria and these cables do meet the requirements
([I of the LaSalle FSAR. (For Item 3.5.b pleaie note that the tagging of cables above a panel is a requirement of HPF WI 500, but because these cables were identified inside the panel, the LaSalle FSAR cable identification criteria was not violated.)
Corrective Action and Date of Full Como11ance:
The field is correcting the specific items listed i.n Atta"hment 2.
The status of this is necrly complete as incicated on the attached copy. The area walkdowns mentioned above will be conducted on a schedule Nhich is commensurate with the scheduled ,rea turnover ,
to the LaSalle Operatin; Department. As stated in Finding #1, it is Project Construction's opinion that no furthur action then l
this is justified. ,

the T. E. Watts letter dated December 23, 1980, Project Engineering agreed with Project Construction that the walhdown inspection will be an effective means of identifying end correcting tagging deficiencies on an area basis, rather then trying to repair or replace each tag individually.

As indicated in Finding fl category B.1, Project Engineer!ng agreed with Project Construction that The illegible jd :ntifica tion basis for their tags on cable is not a major problem.
decision was that there was a 1cw percentage identified in the audit along with the fact that there is a mechanism wnereby cable numbers can ba readily verified by the drawings. Also the arca walkdown will be identifying these types of discrepencien

- concern, since the majority of 'the cables were aarhed juct outside the panels per H. P. Fola, ilork Instruction (9/I-590).
Since Foley's work instruction requires identifien tion bo th above and inside the panels, it cppears that reasonable control is established to address these types of deficiencies in the future.
- Catego ry D.3.b Based upon the fact that associated cables were marked with one
, piece of colored tape and one piece of white tape on a temporary basis, and Foley Corrective Action Reports have documented the locctions where this practice nas ur.ed, a system of control is in place.
Category D.5 In reference to S&L letter 659 dated 10-31-80 (See Att'd) nets or the FSAR nor S&L's Cabic Identification Crit 9ria for LaSalle County Station require that a cable be tagged where it enters an enclosure. Consequently, twenty six associated cable idencified during the audit as having this deficiency are to be dropped, based upon Project Engineerings concurrence (letter dated 2 4-81) with S&L and Project Construction that no violation of th< F AP exist.a.

Enclosure 8 Item 9 Technical Specifications (16)
Commonwealth Edison provided a response to the last (August, 1980) full BWR Standard Technical Specification issue on December 17, 1980. Since that time three additional partial revisions to that " Standard" dated January 14, 1981, February 5, 1981 and March 13, 1981 have been received. On the assumption that no further changes are forwarded by the NRC Staff, Commonwealth idison expects to be prepared to review the then current "Stanoard" specification in mid-April, 1981.
It is our firmly held view that future technical specification discussions must be conducted with the technical branches responsible in addition to the NRC QA Branch. [t is our Judgement that remaining oifferences between Commonwealth Edisn involve technical substance rather than format, and therefore, demand the participation of the technical branch having responsibility for the review of any area in contest.

item .10 Quality Assurance (17)
The NRC Staff has in the form of additional questions on the LaSalle County Safety Analysis Report, requested clarification ano augmentation of the "Q-list". Spec i f ic a l ly , questions 421.6, 421'.7, 421.8 and 421.9 each addresses itself to systems, components, structures and procedures existing prior to TMI as well,as similar items which came under review at ter TMI. The initital response to certain of these questions was accketed in FSAR Amendment $4 (0421.6, Q421.7), supplemental information will be submitted in amendment 56 which will be transmitted in early April, 1981.
Numerous meetings and conferences have taken place between Commonwealth Edison and the Staff regaroing the intent of these questions. Although in general, this interaction was productive, it led to the clear recognition on the part of the applicant that the Staft is proposing a major expansion of the Q-list philosophy, an expansioq which unfortunately is so broad as to be ambiguous and we believe unenforceable.
In general, it can be said that the Commonwealth Edison Quality Assurance Topical Report applies to safety-related and ASME Section III activ'ities and items, and related consumables plus fire protection, security, emergency planning, meteorology and rad waste .
shipments. This commitment is clear, and has been clearly cocumented. However, the apparently trivial adoition of such items as fire protection or emergency pain to a "Q-list" introduces uncertainties in interpretation which are broad and, therefore, ominous. Although specific commitments to the degree of applicability of the QA program to such areas as have been named have already been accepted by the NRC Staff, the addition of the Emergency Plan to the list, for example, would raise questions regaroing specific intent. Woulo all emergency facility design require QA? Woula all emergency communications systems require QA?
Would all public notificati'on systems require QA? We contend the answer is a clear no. Not even the NRC " red-phone" system is aesigned, purchased installed or maintained under a QA program.
In recent discussions with the Staff, it hos been contended that this is not an expansion of previous licensing requirements.
However, specific facts suggest to the contrary.
- 1. Although the Staff has agreed that certain BWR components are not safety-grade and has, through intensive discussions, allowed the use of these components based on augmented technical specification surveillance, the QA Branch requires Q-listing which for non-safety grade components ratses serious questions on regarements for replacement; e.g. level-8 trip, turbine bypass system, and main steam pipng downstream of outboard isolation valve.
2-
- 2. Although the NRC has expli'citly excluded safety-9 fade requirements from most systems and structures requied for the emergency preparedness program, the QA Branch specifically requires the SPOS system, Emergency Response Facilities and meteorological programs (including dose assessment program software) to be Q-listed. This requirement is, in our view contrary to the intent of NUREG-0696, and in fact is so broad a requirement that almost any system, component or structure in the plant could fall under the QA program if these same rules were to be applied uniformly.
- 3. NUREG-0660 Task I.F.1, "Expancea Quality Assurance List," ana
[.F.2, " Development of More Detailed QA Criteria" were not incorporated into NUREG-0694 "TMI delated Requirements for New Operating Licenses" or its subsequent claritication, NUREG-0737. These-tasks were in fact clearly relegated a lesser priocity - not to be resolved until December, 1983.
Although we recognize the well intentioned dedication or the Staff in its imposition of conservative requirements which appear to address long term tasks under NUREG-0660, until a uniform, understandable and enforceable regulatory position has been established, it is not reasonable to require upgrading everything which has an apparent relation to safe plant operation. Without
- definitive guidance, such a policy is so subjective that enforcement woula be almost impossible.
Commonwealth Edison will continue to appropriately delineate all sysems, components and structures which are, in fact,
" safety grace". In addition, we will continue to vigorously enforce through our own Quality Assurance Program all procedureal and programmatic commitments made to date including those related to We fire protection, security, emergency planning and meteorology.
woula also be happy to work with the Staff in the developement of a response to NUPEG-0660 Task [.F.
However, in the event the Staff persists in requiring the addition to a 0-list of all items "affecting safety", including such items as SPOS or emergency facilities, we must formally request a management appeal. That appeal should be at or above the level cf c ngineering in as much as Assistant Director of the Division of se already taken place with numerous discussions and negotiatior the Chief of the NRC Staff - Q A B r a ri c o .

[ tem 11. TM[ Issues (22).
lI.a.([.r.8) Emergency' Procedures, The NRC Staff effort to monitor selected LaSalle County Emergency procedures is substantially complete. This ettort, which was initiatea in August, 1980, has resulted in the use at LaSalle County Unit I of the so-c'alled "sympton caseo emergency procedues" which implement the BWR Owners Group emergency procedures guiaelines .
The Staff has reviewed crafts of these procedures, and in November, 1980 conductec a tsimulator veritication of'the procedure adequacy.
Training on the procedures was initiated at LaSalle County in March, 1981. 'All that remains prior to fina'l procedure signoft is verification of plant specific analytical information upun which the operator response is based. This analysis verification i .s -i n 4
processianc is scheduled to be completed in early April, 1981. It is expected that final completed procedures will be submitted to the Staff by April 15, 1981. Any slippage in that date is expected to be minor. However, it is judged that the substance of the review is complete and tInal procedure implementation coula be verified by the Regional inspection 1and Enforcement authority. For these reasons, it is udged that this item can be closed.
II.b (((.B.7 and II.B:8) Hydrogen Control & Degraded Core Rulemakinq Commonwealth Edison committed in November, 1980 to the inerting of the LaSaHe County Mark Il containments. The operability of the Containment Purge Valves, which was discussed with the Staff in February, 1981 is currently being verified.
However, as was indicated to the Staff, Commonwealth Edison will complete tne program of qualification defined in t he 0. L . liemann letter to D. L. Peoples dated October 23, 1979 and will implement "
any interim required measures detined in that Staff position. The cetail design of the LaSalle County hydrogen control (inerting) system was documented in FSAR Amendment 55.
II.c. (((.E.4.2) Containment [ solation Oependabilit2 l This item also remains open pending satisfactory resolution I
of the containment purve valve operability discussed in item II.b.
a b o v e '.
11 d, (II.F.2) Instrumentation for Detection of inadequate Core Cooling As indicated in NUREG-Obl9, the applicant has, with the assistance of the BWR Owners Group, Justified the adequacy of the existing instrumentation for detection of inadequate core cooling.
Although we recognize the existence in RG 1.97 of a backtit
1 i
/
requirement for what.has been called. core-exit thermocouples,-the
-Guide implementation date is in mid-1983. This applicant will participate with the BWR Owners in the generic ~ resolution of the requirements for this' future modification. At this time, however, no new.information can be. supplied, nor is any expected prior to the scheduled issuance of the LaSalle County operating license. In as much as the requirement for the device in. question-is more than 2 years off anc continuing contriversy exists between the BWR Industry and' the NRC Staf f .and the ACKq and the NRC Staff on the efficacy of the device, we request'that the item not be held open. Its resolution will result from final nodifications maoe on all operatingLplants, including LaSalle County to satisfy RG 1.97.
11.e (II.K.3.18) B&O Task Force - ADS Logic
- This item remains open'in expectation of the submittal by Apr.il -1, 1981 of the BWR Owners Group teasib111ty study for the ADS logic modification to eliminate the need for manual actuation. The results of this analysis are currently being revlewed by the the Owners Group an'd will be submitted to the NRC Staff on schedule, it can be pointed out, however, til a t the concurrent development at LaSalle County of improved" emergency procedures.(as discussed under task lI.C.8)-supports the' advantage of the increased flexibility and-increased diversity for some event sequences afforded by the present design. It is on this basis, wh.ich will be justified in greater aetail by:
i the owners group submittal, that no modificat, ions at LaSalle County Station are Judged to he necessary.'
il.f.(II.K.3.44) Analysis of Transienti with Single' Failure
.The BWR Owners Group submitted the analysis required for this tas3 in the 0.d. Waters letter toD.G. Eisenhut dated December "29,cl980. That report, which is applicable to LaSalle County, was used as a basis for the LaSalle County submittal contained in Section L.34-22 of Appendix L of the FSAR. The fundamental conclusion of tnis analysis is that BWR fuel remains covered during the worst a n t i c 1'p a t e d transient with the worst single failure and a Stuck open ~ relief. This is true without any operator action to
! manually' initiate ECCS or other make-up systems. Manual ADS may be required under certain scenarios.. The symptom based emergency procedures implemented at LaSalle County Station were developed to minimize reliance on event' oriented training. These procedures, it is judged, resolve the NRC Statf open item regarding operator .
response under degraded system conditions. l l

' _1 1. 4 (llI.A.l.2)-Final Emergency F a'c i l i t y Design As you'are aware, the NUREG-0696 facility design definition; date is June 1, 1981. It is unlikely that submittal of information in advance of that1date is possible. However, as was indicated in '
NUREG-0519 the location and stru'ctural design of the LaSalle County Technical. Support Center and Operational Suppert Center are
.oiscussed'in' Appendix L of..the FSAR. 'The permanent LaSalle County
' EOF has not'been discussed as yet but it will be.a facility.whi '
satifies Option 2 of NUREG-0696 i.e. it will be located betwee' 10-20;mi. of the TSC. .The detailed' instrumentation design ,
description and additional configuration information will be provided by June 1. In as much as implementation of this tinal '
design is required after LaSalle County Unit I licensing, the issue shoula not prevent lic,ense issuance. However, the applicant recognizes.the need f or a license condition to control the ulti. mate resolutten of this issue.
II.h. ([II.A.2) Long Term Emergency. Preparedness Resolution of the f our outstanding issues discussed-in Appendix 0 of NUREG-0519 has in part been occomplished.
Each or those items will be addressed separately.
- 1. Provide predetermined EALs for b'igh range effluent monitcrs.
Resolution: This item will be completed as soon as practicable after final installation and calibration of the subject monitors. In as much'as these component's are not required until January 1, 1982, it will be some months before this effort is complete. We expect this effort.to be concluded prior to LaSalle CountyUnit i fuel loading, however, and recommend a condition for ,
the license to verity adeq'udte incorporation of the information. In as much as no contruversy exists over !
- what specifically is required, all that is needed to l close the issue is final calibration completion. This approach is reasonable because Region Ill is already ;
conducting the emergency plan review, i
'2. Provide description of and completion schedule for permanent EOF.
Resolution: As was discussed in item 11 9 above, this information will be provided as required by June 1, 1981 with the implementation schedules defined in i
