l ll RESPONSES-TO INTERROGATORIES BY' STATE?OF VERMONT TO THE VERMONT YANKEE NUCLEAR POWER CORPORATION s

(Set No.: 2):

To the extent that a given interrogatory appears to. seek a legal conclusion, it iscobjected'to, and to the extent that' i

such interrogatories are answered, itis.not to be' considered a legal. answer.

Q.1 Pleasa define what SOV contends isLincluded within the' scope of the term " maintenance program" asLused by..it'in i

its Contention 7.

A.1 Vermont uses the term " maintenance program" to include any policy, procedure, guideline', method,.

i practice or standard which accomplishes, controls,-or relates to " maintenance" as.it-is defined in NRC' Policy; i

Statement on Maintenance of Nuclear Power. Plants (53 FR 9430)'.

The definition in the Policy Statement'is consistent' with the definition in NUREG-1212, Volume-1,." Status of 1

1 9005020240 900424 PDR ADOCK 05000271 t

G PDR N

Maintenance in the U.S. Nuclear Power Industry, 1985,"

Section 1.1.

Q.2 Does SOV contend that NRC imposes any requirements upon the content, substance or form of the VYNPS " maintenance program" as that term is used by SOV in its Contention 7?

If so, please identify, by citation to or identification of a document, each and every such requirement.

A.2 Because of the reliance in the application on the maintenance program for protection of public health and safety in the extended period, the basic requirement is the reasonable assurance requirement of 10 CFR 50.57 1

(a) (3).

In addition the following contain NRC requirements for maintenance:

a.

10 CFR 50. 55 (a) (g) b.

10 CFR 50.49 c.

10 CFR 50.59 d.

Regulatory Guide 1.33 (QA Program Operations) e.

Regulatory Guide 1.58 (ANSI 45.2.6) f.

Regulatory Guide 1.88 (ANSI 45.2.9) g.

Regulatory Guide 1.129 (IEEE STD 450) h.

10 CFR 50.34 (Paragraphs 5 and 6)

Also, because of the NRC's concern regarding nuclear plant maintenance, and its policy, "In view of the progress made to date, as well as the industry's express commitment to improve maintenance, the Commission has decided to hold 1

rulemaking in abeyance for an 18 month period to I

monitor industry initiatives and progress (54 FR 50611),"

l 2

I

P and because of the timing and' content of this proceedinge the " industry initiatives" become NRC' requirements'for:

the licensee's-maintenance-program..

In addition, we recognize the process'of'makingL voluntary commitments as?a source of;NRC maintenance requirements'for the licensee's program..-Through pressurefromhheNRC, licensees often voluntarily commit--

tc= changes rather than incur regulatory forced' shutdowns.

or forced backfits.' Such an example is the Uninterruptible Power Supply system ab Vermont Yankee.

The licensee has committed tofreplace.this system in the q

1990 refuelling. outage-because of poor reliability of the present system.

This is' an example of aul NRC maintenance 4

program requirement, j

Q.3 Please define what SOV-contends ils included.within the:

scope of the term " surveillance program" as used.by'it:in its Contention 7.

A.3 Tne term " surveillance" is used in the broadest sense as expressed in applicableLNRC and industry' i

sources, including the application.

We note that 10 CFR 50.36-(c)(3) defines " surveillance requirements" as requirements relating to test, calibration, or inspection i

to assure that'the necessary quality of-systems and components is maintained, that-facilitycoperation will be I

within the safety limits, and the limiting conditions of-operation will be met.

Draft Regulatory-Guide DG-1001 i

3

b wc defines " maintenance surveillance" as; consisting ~of-collecting data at--specific frequency that supports the.

predictive and; corrective maintenance programs..

A " surveillance program" includes any policy, procedure, guideline, method, practice or; standard which-accomplishes,: controls,-or relates'to surveillance.

The surveillance program is one-aspect-of the, maintenance' program (refer to the response =to-question 1).

Q.4 Does SOV-contend that NRC imposes any. requirements upon the content, substance or from of the VYNPS " surveillance.

program"-as-that term is used by:SOVrin its' Contention 7?:

If'so,'please identify,:by citation to or identification of a document, each andlevery such requirement.'

3 i

1 A.4 The following are surveillance program. requirements.

j established by NRC:

l a.

NRC requires surveillance as-indicated in the

'I technical specifications.

I q

b.

NRC requires surveillance as provided,in the a

inservice testing and inservice inspection program.

c.

NRC requires special surveillance when circumstances dictate.

For example, NRC intends'to require i

special surveillance requirements on flawed feedwater check valves if. licensee does not replace them during the next refueling outage.

i Q.5 Does SOV contend that NRC imposes any requirements =upon

.j the content, substance or form of the VYNPS " program to.

j maintain and/or determine and replace all components-found to have aged to a point where they no longer meet 4

k y<

the safety standards applicable to this~ plant" as that term is-used by SOV in its Contention 77-If so, please identify, by citation to or' identification of a document, each and every such-requirement.

A.5 Vermont contends.that the VYNPS maintenance program does not meet the NRC, requirement of =10 - CFR 50.57 (a) (3), ~

that reasonable assurance hasinot.been demonstrated that 1

the maintenance. program will function:to the' degree

~

relied upon iri the application, to maintain the plant' within its current licensing basis in the extended-

{

period.

To the extent that this. question requests N legal opinion of what this reasonable: assurance'is, or should be, Vermont objects, since this will.be determined by the Board at the end of the hearing.

Notwithstanding and'without waiving'our objection, f

Vermont states that we are not' aware of each and every?

requested requirement.- However, Vermont is aware-that-NRC, as its policy, expects-industry; initiatives to improve maintenance (54.FR 50611),.and as stated in response to question 2, these initiatives become i

.1 l

requirements in this proceeding.

Some of'these industry initiatives are described in an NRC Memorandum of-

\\,

December 28, 1989 (Roe to Murley), " Meeting with'NUMARC j

on Maintenance."

Also, Draft Regulatory Guide DG-1001:

sets requirements applicable to the licensee's program.

l i

Q.6 Please list and describe in as much detail as is j

available to SOV each of the changes to the VYNPC maintenance program, surveillance program, or other i

(

program that, if made'to;the programs, would render 1Sov's Contention 7 satisfied..

A.6 Vermont objects to this question to'the extent that it requests a legal opinion?of reasonable assurance-that the maintenance and surveillance _ programs willl provide adequate protection.

This matter will be-determined at the end of the hearing,by-the Board.' Notwithstanding and a

without waiving-the objection,~ Vermont states thattit would not be responsible at this stage _toLidentify all changes which would render contention VII satisficd:('if this were possible) without fully-reviewing with our

-technical consultant'allithelinformation we seek'in:

discovery.

Nevertheless, programLinadequacies are identified in response:to question 44.

Program modifications to correct these inadequacies are q-necessary.

For example,Lthe' program needs to be' proceduralized rather than relying on individual worker l

skills.

Vendor manual updates'need to be controlled and i

used.

Post maintenance-test requirements need-to be

]

included in procedures.

Adequate staffing resources need to be provided to accomplish review of-completed maintenance requests.

The program needs-to be I

computerized to track and account for each component in the plant and to track surveillance activities so that 4

surveillance and maintenance activities are nos missed.

L 1

-Management needs to take an. active role in trend evaluation.

The trend evaluation process needs to be j:

-?

n

-s p

l I

-formalized to1 establish criteria for action with degrading trends.

Industry initiatives, such as reliability-centered maintenance) which shift the" emphasis from corrective to preventive maintenance, need' to be considered.

Performance monitors for maintenance-1 need to be established,;along with' criteria-for actions based on'such monitors.

Finally, once these,landiother; changes identified as:

-a result of our discovery, are made,-they must be monitored, as-stated in response to question 100.s Q.7 Please define the failure mechanisms that SOV contends are within the: scope,of;the phrases"found to have-aged to' a point where they no longer meet the safety standards-applicable to this plant" as this: phrase-is used byLit-in its Contention 7.

A.7 Refer to the response to-licenseei s set no.

1, question 1.

Vermont, and'probably the industry, is"

\\

unaware of all the applicable;and operable failure mechanisms which affect the structures, systems and-a components, and which will cause-degradation.'and: failures i

in the extended period.

However, we have provided:as complete a list as possible at'this time in the sub--

j parts to contention VI.

1 1

Q.8 Please identify the components or~ classes of components that SOV contends are potentially subject'to each of the 4

failure mechanisms that SOV contends is within the scope of the phrase "found to have aged to a point where they; no longer meet the safety standards applicable to'this plant" as phrase is used by:it in its contention 7.-

7 i

o L

A.8 Again, with the_ qualification noted-in the. priori s

1 response that many' age failure mechanisms are.not understood,:we state that:the'sub-parts of' contention VI'

' identify classes of components that are subject to.the-various failure mechanisms.-

t Q.9 PleaseJdefine'the measureof "sufficiently affective"Las-the term is'used by/SOV in its contention 7.

A.9

-To the' extent that this-question' requests.a legal _

definition = for "sufficiently effective'!, Vermont objectse 4

This is a matter which willLbe datermined by the1 Board at the end of the hearing.

Notwithstanding and'without waiving the objection, we state that " effective" refers j

to the implementation of'the maintenance-program. -Facts d

3, 6,

7, 8,

9, 11 and 12, identified in: response to question-44, relate to aspects of the maintenance program

)I i

which are not "sufficiently effective."

i Q.10 Please identify or describe all of the-bases for-the-definition supplied in response to the-foregoing interrogatory.

A.10 The ultimate basis for the measure of-"sufficiently_

effective" is the decision of the Board.'

1 i

Q.11 Pleasecdefine the measure of "sufficiently...

- k comprehensive"-as the term is used by SOV in its i

Contention 7.

A.11 To the extent that this question requests a legal j

definition for "sufficiently... comprehensive", Vermont 8

. objects.. This.is a matter,which will:be determined by l

i the Board at the end of'the' hearing.

Notwithstanding and without waiving ~the objection, we offer that

" comprehensive" refers to the completeness of the!

j l

program.

Facts'1, 2,,3,(4, 5, 10,tand 1311dentified'in-response'44. relate to aspects of the' program which are not sufficiently comprehensive.-

Q.12 Please : identify or describe all' of. the bases' for the:

definition supplied in~ response to the. foregoing interrogatory.

A.12 The ultimate basis for the measure'of "sufficiently comprehensive"'is the decision of the Board.

Q.13 Does SOV contend that the~VYNPS maintenance program.is not in compliance'with.all~ applicable NRC requirement?-

l A.13 Yes.

Q.14 If your response to the'_ foregoing interrogatory is-anything otherithan an unqualified-negative,;please:

identify, by citation to or: identification of'a document, each and every such. requirement withlwhich SOV contends' the VYNPS maintenance. program is notlin. compliance, and, i

for eachisuch requirement, each and every reasonzwhy.SOV?

contends that the VYNPS maintenance program'is_not in-compliance with it.-

A.14 Vermont contends that the VYNPS maintenance program'

.does not meet the NRC requirement of 101CFR ' 50. 57 (a)[(3 ),

f 11 that reasonable assurance has not been demon'stratedithat 4

the maintenance program will function to-the degree and I

i in the manner relied'upon in the application to. maintain L

the plant within its current licensing basis in the l

extended period.

To the extent that this question 9

4

.c

4 o

t requests a legal opinion of what constitutes this reasonable assurance, Vermont objects,'since-this will'be~

determined by the Board at the end of the hearing.

Notwithstanding: and without-waiving: the objection, Vermont states that facts indicating; maintenance. program aspects which'do'not demonstrate reasonable assurance, are provided'in response to question 44'.-

Q.15 Does.Sov contend-that'the VYNPS surveillance. program is-not in compliance with any applicable NRC: requirement?;

A.15 To the extent that the surveillance ~ program ~is one aspect of the maintenance' program which. we ' contend 'does not meet'NRC requirement (s)- (refer to-the responses to j

questions 13 and 14), we respondfyes.

Q.16 If your response to the foregoing interrogatory is-anything other than an unqualified-negative,.please identify, by citation to or identification of a document,.

each and every such requirement.withLwhich SOV1 contends the VYNPS surveillance program is-not~in compliance, _ and, -

for each such requirement, each and every reason why SOV-contends that the VYNPS surveillance; program. is ~ not irr compliance with it.

A.16 Refer to the response to question 14. : Fact 7, in response to question 44, specifically relates to surveillance.

t Q.17 Please describe what SOV means by the phrase "no closure' showing improvement" as used by it in sub-paragraph "b."

of its Contention 7.

A.17 By "no closure showing improvement", we, meant that at the time of the filing'of the contention, the'NRC l

10 s

+

i Maintenance Team had notireinspc *.ed and' issued a-followup inspection report indicatingLthat corrective action had been.taken forLall of the listed weakness.

In addition, as noted in response 18, once weaknesses:are identified, two distinct meanings of " closure" come'into being:

closure by thelNRC-Maintenance Team,fand closure; by Vermont.

Q.18 Please describe the set of items, events or circumstances-that would constitute'" closure showing improvement">

within-the meaning of sub-paragraph "b." of. Contention 7 such that, were any'such-item,-event or circumstance to:

occur or, exist, sub-paragraph "b." would no longer be.

true.-

A.18 To the extent this question calls for-a legal opinion of what would' constitute 1 reasonable-assurance' that the listed weaknesses were1 corrected,.it'is objected to,.and is a matter which.willlbe decided by the Boardfat the end of the hearing.

Notwithstanding'and:without

.i waiving the objection, Vermont. states,;that once weaknesses are identified, two distinct' meanings of

- j

" closure" come into being.

In the one sense, closure will occur when the NRC Maintenance Team:reinspects, and issues an inspection report indicating the weaknesses;

~

have been corrected.

However,'once the weakness-is=

identified, attention is focused.on'it. -Vermont reviews 1

the circumstances surrounding the weakness-and independently determines the extent and nature of the i

l 11 i

I

b

+

-c 6L weakness and its-solution.

Closure ~ay Vermont'is, therefore, independently-evaluated-and determined..

Q.19 If the-NRC Staff-were to publisN aLdocument or'make.a finding to the effect that any item' described by it'in;an Inspection Report _("IR") is now closed,;would.SOV acknowledge:that-such-publication or. finding constitutes'

" closure" asithat term is used by SOV'in;sub-paragraph:

"b." of its' Contention 7 of the_ item in~ respect of which' the publication or finding _ were made?:

i A.19 ReferLto the previous response.

Q.20 If your response to the-foregoing interrogatory is anything other than an unqualified affirmative, please>

describe all of the reasons why such a1 publication'or finding would not constitute " closure."-

A.20 Refer to the response to question 118.

1 Q.21 Please identify each-of the-issues _ adverted 1tolin Contention 7, including sub-paragraphs "b.",

"c.",~"d.",1 "e.", "g.",

"h. (1) ",

"h. (2) ", "j.",

"k.";

"m.",.and "n."

thereof and sub-paragraphs "1.", "n." and-"o." of-Contention 8, that Sov acknowledges have'been_" closed" as of the date on which your answers:toithese interrogatories are filed.

A.21 Vermont is not aware, and does not consider,'that any of the items have been " closed" as of=the:date of these answers.

Q.22 Does SOV contend that all vendor-recommended preventative maintenance must be performed in order for.the VYNPS'-

l maintenance program:to be adequate to prevent aging failures?

Please give all the reasons for your answer and, if your answer is qualified, all of the qualifications applicable to VYNPS and the reasons for l

them.

A.22 No.

and/or' concurrence by the vendor.J 'The types of-analyses and testing required-vary according to the type of component, the' environment,-the operating mode, the current licensing basis, and the specificLvendor-recommended' preventive maintenance item.

Q.23 Please-describe exactly how'SOV contends that post' maintenance testing must be' incorporated?into'the.

maintenance procedures in order;for the procedures-to be) i adequate..

A.23 To the extent.thatsthis question callscfor a legal' definition of what'would constitute reasonable' assurance 3-that the lack of post maintenance testing 1 requirements 11n?

maintenance procedures was' corrected, itcis objected to, and is a matter which will'be decided by,the Board at the

.end of the hearing.

Notwithstanding;and.without: waiving-this objection, Vermont statesLthat proceduralizationD of?

these requirements-is necessary to assure consistent application of post maintenance' testing, rather than depending of the random skills of,the individual preparer or reviewer in the maintenance or operations department.

Vermont notes, from section 4'.7 of Draft. Regulatory" Guide) l DG-1001, that:

1

'"The work control process'should be based on j

procedures that provide for... post maintenance-

~

testing, return-to-service procedures..."

1 Such procedures'should provide systematic guidance to:the-craftsman, should-be technically correct,' complete and' up-to-date; and should be. presented using sound human.

factors principles.

Q.24 If SOV rentends that post maintenance testing;mus: oc.

procedural 1L?dnin order for the maintenance prog;am-to-be, adequate, plu3nc describe the steps that SOV= contends must be included in ths procedures for insuring that-post maintenance testing is_comprahensive-enough for a givenL

. maintenance task.

A.24 To the extent that "ccaprehensive enough" in this:

question calls for a legal defin',. tion of: what would' constitute reasonable assurance that theLlack'of post

'I i

maintenance testing requirements'in maintenance procedures was corrected,.it is objectedito, and isfa-

1 matter which_will be decided by the board atithe end'of.

i the hearing.

Notwithstanding andjwithout' waiving this objection, Vermont states that we are unable to) identify 4

specific procedural stepsLwithout a'cesstto'the c

maintenance procedures, which.we have not beenigranted.

Q.25 Please describe what SOV means by its assertion that-"PRAL concept not incorporated into Vermont Yankee maintenance-program" at page 43 of its contentions.

1 A.25 By the use of this statement, "PRA concept not i

incorporated into Vermont Yankee maintenance program >a l

which is quoted from IR 89-80, Vermont means that thn PRA concepts of reliability-centered-maintenance, along.with 1l other industry initiatives, should be employed to provide 14 1

l

.l

assurance in the' areas' identified-by; Facts-2 andi 13:in response to question 44.

c Q.26 Please. describe in detail' exactly how SOV' contends that "PRA concept" should be " incorporated" into-the VYNPS:

maintenance program.

A.26~

To'the. extent that this question calls for aJlegal defin(tion of what would constitute reasonable assurance--

that the lack of. incorporation of PRA: concepts-into the-t maintenance program was corrected, it is objected-to, and is a matter which.will be decided by the Board at.the'end-of the hearing.,.Notwithstanding.and without waivingithis objection, Vermont states that~ practices"which contribute to an effective maintenance program are.proactive'as opposed to reactive, that' preventive maintenance is emphasized over corrective maintenance. JVermont. Yankee's' maintenance program has been characterized as a program!

j with weak preventive maintenance, needingLa more l

~

proactive posture, and with naintenance. activities heavily oriented to corrective maintenance.

In a proactive program, PRA concepts are usedito provide a systematic consideration of~ system' functions.and the ways in which functions can fail, leading'to the-

.1 identification of applicable and effective preventive maintenance tasks with consideration of safety and economics.

15 t

,1 i

Q.27 Please state,your basis <for,'and each authority on which' you rely.in' support of,.-your response'to the foregoing i

interrogatory.

j.

A.27 Characterization of Vermont Yankee's maintenance f

program'is drawn from-the: safety system functional inspection (SSFI): conclusions! Presented at the NRC Regioni I meeting of January 26, 1989.

PRA concepts are employed ~

by reliability-centered maintenance. techniques,: which are discussed in EPRI NP-6152, Volume 1, January 11989,

" Demonstration of'Reliabilityacentered Maintenance,-

i l

Volume 1: Project Description."

l l

Q.28 Please identify-each and every benefit thatLSOV contends A

~

would result from the." incorporation" of "PRA concepto:

4 into the VYNPS maintenance program,~ and please state each~

and every reason'whycSOV contends that such benefit would.

1 result.

A.28 EPRI NP-6152 identifies " realignment'of maintenance-

-i resources to improve.overall plant availability;and i

safety," and " producing a more favorable preventive' maintenance to corrective: maintenance ratio," as objectives of reliability-centered maintenance.

l f,

Q.29 Does SOV contend-that its asserted non-incorporation'of "PRA concept" renders the VYNPS maintenance program,,or.

-the operation of VYNPS, in any respect:not in compliance with any regulatory requirement of the Commission?

A.29 Vermont objects to this question 1to theuextentothat' it asks for a legal. opinion of whether non-incorporation of "PRA concept" defeats a demonstration of reasonable 1 a

assurance.

This will be decided by the. Board as a result of the hearing.

Notwithstanding and without waiving this 16 l

+

objection, Vermont states'that in response to question 44.

we have identified _ facts-relatingLto a failure'to-demonstrate reasonable assurance.-- Facts 2 and 13Lrelate to non-incorporation of "PRA concepts." ! Incorporation'of "PRA concepts" would assist toward demonstrating reasonable assurance that the maintenance program would' function as claimed in the application.

Q 30

'If your answer to Interrogatory No. 29 is anything other than an' unqualified negative, please state'each and:every-regulatory requirement of the commission with which SOV contends VYNPS is not-in' compliance on account of!the non-incorporation lof "PRALeoncept"'into the VYNPS maintenance program.

A.30 Refer to the previous response.

Q.31 What significance,cif_any, to the; question of whetherithe

" incorporation" of "PRA concept"-into a maintenance program is necessary to the permissibility of plant-3 operation does SOV. attribute to the fact that the commission has-declined.to impose 1such-a requirement through the promulgation ofca regulation? :Please state in detail the bases for your-response.

A.31 Vermont objects to this questionson the basis that it asks for a legal opinion, and'that the Commission's 1

1 decision not to the promulgate a regulation, assuming the activity is not prohibited, is not a matter of substance in this proceeding.

Q.32 How, if at all,,does SOV contend that the " incorporation" of "PRA concept" into the VYNPS maintenance program-would modify the safety margins established by the existing!

Rather than agree with this statement, Vermont l

asserts Contention VII.

Vermont has not been granted' access to much of licensee's maintenance internation, and, therefore, feels it is not able to. identify each and every fact in disagreement with this statement until it fully reviews with its technical consultant material

)

which is sought from discovery.

Nevertheless, at this point we have determined the following facts, with their H

stated bases:

-t 1.

Implementation of the maintenance program has relied too much on worker skills rather than on consistent, well developed procedures.

This is based'on

^

evidence from the report of the NRC Maintenance Team t

review (IR 89-80), "NRC Maintenance Team Report," and the summary of Westec Incorporated safety system functional inspection (SSFI) provided at the NRC Eegion I meeting of.

January 26, 1989, "Westec SSFI Summary."

\\

t 2.

The program has relied on program elements which were established at startup rather than-on i

27 l

a

I l

requirements'which have been comprehensively reviewed and i

updated to latest methods.

There has been a reluctance j

to modify the maintenance program to' meet industry l

t standards.

This is based on evidence from the NRC

'?

Maintenance Team' Report, the Westec SSFI' Summary, and LRS-F Incorporated, Reports #3-88'and #2-89.

[

3.

. Updated recommendations from vendors have not'

~

been controlled.

This is based on evidence from the NRC r

Maintenance Team Report, the Westec SSFI Summary, and'LRS I

Incorporated, Report #2-89.

4.

The program has not included a requirement for management review and evaluation of trends.

This is f

based on evidence from-the NRC Maintenance Team Report.

5.

The program has not included a long term plan to reverse degrading trends.

This is based on evidence from the NRC Maintenance Team Report.

6.

Sufficient engineering resources'have not-been allocated to complete the review of maintenance l

l requests promptly.

This is based on evidence from the n

NRC Maintenance Team Report, the Westec SSFI Summary, and 3

LRS Report #3-88.

7.

The maintenance program has not provided the control to avoid missed surveillances and preventive maintenance.

This is based on evidence from the Westec SSFI Summary and LERs 88-03, 88-13, 88-14, 89-10, 89-23, and 89-24.

r 28 ii

'i r

I

8.

The maintenance program has not detected, or has left undetected for long periods, degraded components.

This is based on evidence related to flaws in the feedwater check valves, incorrect wiring and post modification testing of the " squib" valves, and inoperability of service water check valves (LER 89-17).

9.

The maintenance program has had maintenance errors or omissions which have caused failures, or has allowed actions which could have led to failures or the inability of components to perform ~their safety function.

This is based on evidence from LER 89-14, LER 88-09,-and the Westec SSFI Summary.

10.

Control and evaluation of equipment has relied on worker skills rather than on a comprehensive and all-inclusive master equipment list.

This is based on evidence from the NRC Maintenance Team Report and LRS Report #2-89.

11.

The maintenance program'has failed to I

identify reliability problems and/or obsolete equipment and take prompt action.

This is based on evidence from the NRC Maintenance Team Report, LRS Report #3-88.

12.

Instances have occurred in which the maintenance program has been unable to determine and replace aging components.

This is based on evidence from the NRC Maintenance Team Report and LERs 89-07, 87-07, k

85-07, 84-11, 89-03, 89-04, 89-19,,and 89-21.

t 13.

The maintenance program has'been characterized by weak preventive maintenance, with activities heavily oriented to corrective maintenance.

This is based on evidence from the Westec SSFI Summary.

The evidence described above is supplemented by the expertise of Mr. H. Shannon Phillips, whose I

qualifications have been provided in-response _to licensee's interrogatories, Set No. 1.

Q.45 Please define the term " age-related problem" as it_is used by SOV in sub-paragraph "d." of Contention 7.

A.45 By " age-related problem," we mean any action or lack-of action which causes or allows structures, systems and components to age to a point where they no longer meet the safety standards applicable to the plant.

Q.46 Please define the term " timely fashion" as it is used by SOV in sub-paragraph "d." of contention 7.

A.46 The term, " timely fashion," is quoted from IR 89-80.

To the extent this question asks what the author i

meant by this statement, it is unanswerable, since-the author's meaning is unknown to Vermont.- Vermont's meaning in quoting the term is that it is an aspect of a weakness in the Vermont Yankee program identified by a respectable author.

Q.47 Does SOV contend that there is an applicable NRC requirement specifying the maximum amount of time within which VYNPC must perform a " review (of) the 30 l

q 1

I

. __ __u

I k

appropriateness and technical adequacy of completed-l maintenance activities?"

If so, please identify, by citation to or identification of a document, each and j

every such requirement.

A.47 Vermont is unaware of'each and every NRC requirement t

~

for maintenance programs.

However, licensee claims, as a f

basis for-the proposed life extension, that mechanical components are periodically inspected and maintained, and t

that age-related degradation will be identified and corrected, and component functional capability maintained.

Yet, IR 89-80 reports weakness with regard I

i to the review of maintenance activities for i

appropriateness and technical adequacy.

Thus, the applicable requirement is the. reasonable assurance 9

requirement of 10 CFR 50.57(a) (3), which Vermont contends y

has not been demonstrated.

t b

Q.48 Does SOV contend that, without regard to any applicable NRC requirement, there is a maximum amount of time within which VYNPC must perform a " review (of) the appropriateness and technical adequacy of completed maintenance activities?"

l A.48 Yes.

Q.49 Unless your answer to the foregoing interrogatory'is an unqualified negative, please identify what SOV contends is such a maximum amount of time and provide each and every reason why SOV contends that its time is the j

maximum allowable.

A.49 To the extent that this question requests the maximum time which would provide reasonable assurance that the procedural step was effective, it calls for a 31 o

I

legal conclusion and is objected to,'and is a

'j i

determination.which will be made by the' Board at the end 1

of the' hearing.

Notwithstanding and without waiving this 1

objection, we offer that we are not able, at this time, i

l to supply quantitative values for these attributes which i

demonstrate any. effective program.

Measurable attributes upon which to judge the effectiveness of the procedural' l

j step, " review (of) the appropriateness and technical j

i adequacy of completed _ maintenance-activities," are l

backlog and maximum amount of time elapsed since j

completion of the activities; Additionally, an effective 1

program will set priorities in the review of the 1

appropriateness and technical adequacy of completed l

maintenance activities, such that activities involving critical structures, systems, and components will be given a higher priority for review than will non-critical structures, systems, and components. -Vermont Yankee has not demonstrated that it has set such priorities for its t

process of reviewing completed' maintenance activities.

Q.50 Please identify each and every instance'of which SOV is aware in which, after the maintenance or repair of-a I

component, the lack or untimeliness of a " review (of) the j

l appropriateness and technical adequacy of completed r

maintenance activities" subsequently led to "a failure before correction."

A.50 Vermont is aware of the failure of the RCIC-21 valve as a result of maintenance activities (LER 89-14), and j

the maintenance related failure in the turbine pressure i

32

~.-..

l l

I control system (for example, LER 88-09).

While it is i

(

possible that untimeliness of the " review (of) the l

l appropriateness and technical adequacy of completed l

maintenance activities" played a part in'these failures, i

Vermont has not been granted access to the review records-of maintenance activities for these, or any other events,

(

upon which to base a response to this question.

Q.51 For each instance identified in response to the foregoing j

interrogatory, please provide each and-every reason why SOV believes (if it does) that the event in question was related to aging.

A.51 LER 89-14 states, "the root cause of this event is I

~

believed to be premature end of life [ sic) failure."

LER 88-09 states, "the suspected root cause of this event is the malfunction of the MHC control oil system...it is.

[

suspected that the MHC control oil system may have operated improperly due to dirt / grit lodging in the oil pressure control valves."

The~ buildup of dirt and grit;

{

is an aging phenomenon.

Q.52 Please define the term " timely updating" as-it is used by SOV in sub-paragraph "e." of contention 7.-

A.52

" Lack of timely updating" refers to,-and is considered equivalent to, the NRC Maintenance-Team statement of program weakness in that same sub-part e.

{

l Q.53 Please describe the types of circumstances under which SOV understand VYNPC vendor-manuals to be updated.

For each such type of circumstance, please explain the mechanisms by which, as SOV contends is the case, t

33 i

a i

s.

a

~

l' l

"information on aging equipment from the vendors will be-critical to prevent failure of safety equipment."

i A.53

. Vermont has not been granted access to. vendor manuals er vendor manual updates, nor has it reviewed this material.

It is conceivable that a vendor manual update could incorporate safety-significant changes to i

recommendations as a result of operating experience, which, if not incorporated into the vendor manual, would l

l be ignored by the maintenance program, and-thus result.in' i

1 failure of the equipment.

[

Q.54 Please identify each and every. instance of which SOV is l

aware in which an " update" of a vendor manual contained

(

information not previously available that was " critical l

to prevent failure of. safety equipment"-in which the l

criticality was directly related to aging.

l A.54 Vermont has not been granted access to vendor manuals and vendor manual updates, and has not completed

.i its evaluations in this area.

However,-Vermont offers,:

for example, that 1) vendor or EPRI/NMAC information may have been available to prevent the burn out of the RCIC-21 motor (LER 89-14), and 2) that the safety evaluation.

may be incomplete in that it neither proved nor considered whether the valve would have prerformed its function in the accident environment, nov did'it evaluate the consequences of being unable to close the RCIC-21 valve once it was opened.

The RCIC-21 valve is safety equipment, and LER 89-14 identifies the root cause as j

premature end of life failure.

Q.55 Does SOV contend that there is an applicable NRC requirement specifying the nature and content of trend analysis programs applicable to the VYNPS maintenance program?

If so, please identify, by_ citation to or.

identification of a document, each and every such requirement.

A.55 Vermont is unaware of each and every NRC requirement for' maintenance programs.

However, as stated in sub-part g. to Contention VII, licensee-relies on trend analysis to indicate decreased equipment reliability and expected life in the extended period.

Yet, IR 89-80 reports weakness in the evaluation of adverse trends.

Thus, the applicable requirement is the reasonable assurance requirement of 10- CFR 50.57(a) (3), which Vermont contends has not been demonstrated.

Q.56 Please define the term " Reliability-Centered Maintenance-(RCM) program" as used by SOV' in sub-paragraph "h. (1)"

(hereinafter used to refer to the'first of the two sub-paragraphs labelled by SOV "h ") of'its contention 7.

A.56 A reliability-centered maintenance program is a systematic consideration of system functions and the ways in which functions can fail, leading to the identification of applicable and effective preventive maintenance tasks with consideration of; safety'and-economics.

Q.57 Please define the term " life-extension" as used by SOV in.

sub-paragraphs "h. (1)" of its Contention 7.

A.57 Vermont uses the word, extension, as used on page 1 of Attachment 1 to the application:

35

.i

.- - - ~

I L

l 1

l "This extension is within the range permissible...."

In the context above, " extension," refers.to "a change to

>j the expiration date of the current license."1 Vermont equates "a change to the expiration date of the current license" to " plant life," or simply to " life."

Therefore, the proposed amendment constitutes " life X

p extension."

Vermont further uses the term " life L

extension" to refer to the extended service lives of the l

l I

structures, systems and components of the plant which result from " plant life extension."

\\

Q.58 Would SOV acknowledge that, if what the authors of.EPRI NP-6152, (January, 1989) meant by the term " life.

extension" does not include the authorization sought by this operating license amendment, then sub-paragraph I

"h. (1)" of Contention 7 is without basis?

A.58 Vermont objects on the basis that this question is a i

hypothetical question with no foundation in facts which are of record.

Q.59 If your response to the foregoing. interrogatory is other-l than an unqualified affirmative, please state each and every fact or circumstance that SOV contends provides a basis for sub-paragraph "h. (1)" of contention 7.

t A.59 The concepts of reliability-centered maintenance apply to the life extension proposed by this amendment, whether or not the authors of EPRI NP-6152 had the life extension of this proposed amendment in mind.

36 y

i Q.60 Please describe what SOV understands to be the special effectiveness of RCM for " life-extension."

J A.60 Reliability-centered maintenance can result in realignment of maintenance resources-to improve overall plant availability.and safety, and a more favorable preventive maintenance to corrective maintenance ratio.

As part of the reliability-centered maintenance program,.

controlling degradation mechanisms can be identified, important predictive and preventive maintenance program 3

features can be determined, and plant data and record-

-i keeping requirements to minimize-the potential for 3

unanticipated failures can be established.

Data can be collected and evaluated to determine specific evaluation documentation requirements for aging mechanisms that have been identified as potentially limiting to.the life-of i

critical components.

Recommendations can be developed to modify data and records requirements to support component reliability assessments.

One task of: the reliability--

3 centered maintenance program can be to reduce the rate of life-limiting degradation mechanisms and to monitor the L

4 rate of degradation in order to avoid failure or I

I expiration of qualified design life.

Vermont notes that all of the above-is essentially l

l the expectation that the licensee places on the maintenance program in its application for the operating 4

l license extension.

Q.61 Does SOV contend that there is an applicable NRC requirement VYNPS have in place, or have made a i

commitment to, an RCM maintenance program?

If so, please identify, by citation to or identification of a document, each and every such requirement.

g A.61 Vermont is unaware of each and every NRC requirement for maintenance programs.

However, as stated in

.i responses to the previous question, the licensee relies l

)

t on its maintenance program to serve the functions, in the

[

extended period, which could be provided by a reliability-centered' maintenance program.

Yet licensee has not described the use of reliability-centered maintenance techniques and the NRC Maintenance Team has l

identified the lack lof the use of PRA concepts as a weakness.

Thus, the applicable requirement is the reasonable assurance requiremont of 10 CFR 50.57(a) (3),

which Vermont contends has not been demonstrated.

[

Q.62 Does SOV contend that, without regard to any NRC l

requirement, RCM is the only way that a maintenance program can be effective to combat the effects of aging?

l A.62 Vermont objects to this question to the extent that i

l it requests a legal opinion of whether a reliability-l l

centered maintenance program is'the only way to provide reasonable assurance in the context of 10 CFR 50.57 (a) (3).

This is a matter which will be decided by the Board at the end of the hearing.

Notwithstanding and without waiving our objection, we respond, no.

i Q.63 If your response to the foregoing interrogatory is anything other than an unqualified negative, please-state each and every reason.why SOV contends that RCN is the only way that a maintenance program can be effective to r

ccabat the effects of aging.

A.63 Refer to the previous response.

j Q.64 Please state each and every alternative method to RCM that SOV is aware of and, for each such alternative, state whether SOV contends that the alternative is superior to, equal to, or substantially inferior to RCM for correcting the deficiencies alleged by SOV in its contention-7, and state each and overy reason why SOV so r

contends.

A.64 Vermont objects to this question to the extent that

(

it requests a legal opinion concerning reasonable

[

assurance.

This is a matter which will be determined by the board at the end of the hearing.

Notwithstanding and without waiving this objection, we offer'that we have not performed any evaluation to determine, and therefore are unaware of, alternate methods to reliability-centered 1

maintenance which would accomplish the same function.

l Q.65 Does SOV agree without qualification with the'following statement" "RCM is primarily a means of decreasing maintenance costs and increasing plant' economics, accomplished.by eliminating

-i unnecessary preventative-maintenance and prioritizing the rest toward those systems and components with.the greatest-impact on megawatt-hours produced?"

qualification is based.

information which SOV contends establishes the qualifications of the person), of any person on whose expertise Sov relies for the qualification or state that SOV does not rely upon'the expertise-of any person for the qualification.

A.71 Vermont contends that was true in October 1988, at-the time of the LRS Incorporated Report.

Vermont is not 45

?

s

i o

o aware of the extent to which the licensee has acted on this LRS recommendation.

But Vermont further contends that management has been reluctant to meet new industry l

standards and had not established a policy for reviewing the maintenance policy and program for current trends.

These are shown by facts, along with evidence and j

i expertise relied upon, provided in response to question 44.

Q.72 Please state each and every' reason Soy contends (if it does) that'a " review (of) the industry practice in maintenance planning to determine if the industry trend in establishing formal maintenance planning groups would aid in increasing productivity in the maintenance area"-

would materially impact safety through the balance of the extended VYNPS license term, j

A.72 Formal maintenance-planning groups can take the form of planning groups for such areas as maintenance policy, i

program specifics, professionalism, outage management

'i assistance, and human performance evaluation.

While we are aware that licensee-has taken some initiatives in the area of maintenance planning, we are similarly aware of.

the Westec Incorporated SSFI general conclusion that licensee is reluctant to modify maintenance programs to j

meet industry standards.

We are also awsre of the NRC-Maintenance Team identified weakness of the lack of q

comprehensive and structured review for adequacy and' applicability of the plant's maintenance requirements.

In sum, we believe the lack of " review,(of) the industry 46 a

practice in maintenance planning (which) would aid in increasing productivity in the maintenance area" can i

contribute to the lack of demonstration of reasonable j

assurance that the proposed action will protect the 1

k sub-paragraph "j" of its Contention 7.

i 1

t i

A.73 Vermont quotes the phrase, "better computerization of the MR system" from LRS Report, #3-88,'because-we I

agree that.better computerization is needed.

The Vermont Yankee "Visicard" system is a manual system which was established before the development of personal computer technology, and is outdated. -Computerization would allow

{

the creation and use of a master equipment list, and will allow tracking of maintenance activities.

Q.74 Please state each and every reason SOV contends (if it does) that "better computerization of the MR system" d

would materially impact safety through the balance of the extended VYNPS license term.

A.74 Better computerization of the MR system would allow f

better tracking of maintenance activities.- This could lead to reducing the number of missed surveillance and maintenance activities which could have safety significance.

Better computerization would also provide a master equipment list which would assist in tracking i

its Contention 7.

A.75 Vermont quotes the phrase, "bester utilization of l

the Assistant to the operations Supervisor" from LRS i

l Report, #3-88, because we agree that it would be desirable to reduce or eliminate shift supervisor review time.

Q.76 Please st. ate each and every reason SOV contends-(if it i

does) that "better utilization of the Assistant to the operations Supervisor" would materially impact safety through the balance of the extended VYNPS license tera..

A.76 The LRS Report gives the impression that review of I

i maintenance requests place a significant burden on the shift supervisor.

Safety is impacted by either 1) diverting shift supervisor from other shift monitoring I

duties, or 2) delaying completion of maintenance requests.

Q.79 please state each and every reason why SOV contendsL(if it does) that. " pay ing) sufficient heed to- [the operators) desires [for hardware repair and replacement" would materially impact safety through the balance of the extended VYNPS license term.

A.79 The policy, practice or occurrence of-not " pay (ing) sufficient heed to (the operators) desires for hardware repair and replacement" is an apparent weakness in the maintenance program.

The maintenance program is offered as a basis for the assurance that the proposed amendment-will protect public health and safety.

This identified weakness contributes to the lack of assurance that the-maintenance program will perform as claimed'in the application.

" Failure to maintain:the:Uninterruptible Power Supply (UPS)... to' meet reliability standards" refers to

^

the fact that the existing UPS is a reliability outlier,,

which licensee has committed to replace during the next' refueling outage.1 Q.103 Please set forth'each and every~ reason.why SOV contends that what is referred to by Sov in sub-paragraph 1"m." of its Contention 7 as "the failure to maintain the a

Uninterruptible' Power Supply" demonstrates "a history'of:

Q.104 Please set forth each-'and every reason.why SOV contends the.t.what is referred.to by SOV in.sub-paragraph "m." of l

its Contention 7 as "the failure to maintain...the toxic L

I Q.105 Please define what~is. meant'by SOV by the term ~

" reliability standards" as it is used by.SOV in sub-paragraph "m" of'its contention 7.

A.105 Vermont is aware that INPO-uses the' Nuclear Plant.

Reliability Data System (NPRDS) and the Component Failure Analysis Report (CFAR) to identify and report significant component failure rate problems.
