ANSWER: Except as otherwise noted', Illinois Power has no computer codes relevant to Interrogatories 1, 2, 3, 5 and 6.

8 INTERROGATORIES

[1. Describe and provide IP's, BWR Owners.

Group's, and any other research and studies pertaining to the CPS central water level monitoring system.]

ANSWER: The primary studies prepared by the BWR Owners' Group. ("BWROG") on the BWR water level measurement system g - ( "WLMS " ) are contained in the two proprietary reports:

O

L f

Iz SLI-8211; " Review of BWR Reactor Vessel Water

' Level Measurement Systems," prepared by S. Levy, Inc., July 1982.

.SLI-8218; " Inadequate Core' Cooling Detection in Dolling Water-Reactors," prepared by

,j S.: Levy,LInc., November 1982.

'The first report is an in-depth evaluation offthe WLMS used for BWR/2 through BWR/6 product lines. This report g identifies several potential concerns.related to WLMS indica-tion accuracy 1during_ severe accident / transient' conditions and recommends modifications to enhance _ system capability.

g It further recommends that a plant; specific evaluation of the WLMS be performed to evaluate-the possible effect of each recommendation on each plant.

g. The second' report evaluates the ability of the WLMS to detect inadequate core cooling ("ICC"), discusses alternative ICC detection devices, and provides a risk assess-g ment comparison of_the effectiveness of reducing core melt frequency for~ alternate ICC devices and the modified WLMS.

This report concludes that if the appropriate recommenda-

, tions of SLI-8211 are incorporated into the WLMS, following a-plant specific evaluation, then there is no significant additional risk reduction achieved by providing additional y and diverse ICC detection devices. .

The Nuclear Regulatory Commission ("NRC") has sponsored evaluations of the WLMS. One report, NUREG/CR-3652,

-s D

3

" Eval'uation of Instrumentation for Detection of Inadequate-Core Cooling in Bolling ~ Water Reactors," Oak Ridge National.

Laboratory - April 1984, concludes that_use of multiple, redundant cooling level measurements, with' overlapping ranges, can- be a ~ reliable basis ' for indication of approach' to an ICC condition when considered in correlation with the other l '. -

_ control and safety systems. The_NRC referred to another report, EGG-REP-6396 (proprietary) prepared under NRC contract by EG&G/ITI in'its evaluation of SLI-8211'and'SLI-8218.

.IP is currently finalizing its Clinton-specific evaluation of the WLMS. The Clinton WLMS design, as. modi-fled by the rerouting of sensing lines and relocation of  ;

flow orifices, satisfies the recommendations of SLI-8211.

An interim report on the,Clinton-specific WLMS evaluation was issued to the NRC via the letter U-0749, dated October 10, l 1984.

[2. What has IP done to address the need for level monitoring to the dome in BWRs?

Provide relevant documents.]

ANSWER: The present CPS WLMS shutdown range monitoring devices i are capable of measuring reactor water level up to the dome of the reactor vessel.

[3.a. What instrumentation is proposed for 3 detecting inadequate core cooling in case of an abnormal occurrence? Provide relevant documents.]

b I -

S

q;

^

c ANSWER: IP' intends to utilize the reactor vessel WLMS, as described in CPS FSAR Sections 7.4 and~7.5, to determine the adequacy'of core cooling. The appropriateness of using,this system to detect inadequate core cooling is discussed-in the BWROG: Sponsored Report SLI-8218, " Inadequate Core Cooling Detection in. Boiling Water Reactors," prepared by S. Levy, Inc., November 1982.

[3.b. Has this instrumentation been tested?]

ANSWER: The WLMS to be used at CPS was developed by GE and.

, is typical of that used in currently operating BWRs. Operat--

ing experience and: testing demonstrated the instrumentation performance to be proper, accurate, and reliable.

[3.c. If so, describe and provide the test and 9 studies which have been conducted per-taining to the efficiency of this in-strumentation.]

ANSWER: Generic studies of the WLMS are described in response 9 to Interrogatory No. 1 related to this contention. A Clinton -

specific evaluation is also discussed in that response. The GE tests and studies concerning water level instrumentation 9 are not in the possession, custody, or control of Illinois ..

Power. They are in the possession of GE.

[3.d. Does IP plan on following the NRC's recom-mendation of further instrumentation, 9 specifically incorporation of core-exit thermocouples for BWRs? If so, provide l

the plan. If not, provide the documents and studies justifying IP's position, and all other relevant documents and

, studies.]

9:

i

)I ANSWER: IP~ understands that the NRC is still reviewing'the question'of core-exit thermocouplesDfor BWRs. In January of.

'1982, the BWROG agreed.to sponsor programmatic evaluations.

h .of BWR WLMS designs and-ICC detection and hardware. 'In July _ .

of 1982, the BWROG submitted the results of_its evaluation of BWR WLMS designs to the NRC in SLI-8211, entitled " Review i.

) of BWR Reactor Vessel Water? Level Measurement.Sirstems", which -

is' discussed in the Answer to Interrogatory No. l'above.

( The BWROG also_ sponsored preparation of'SLI-8218, f "

D' entitled " Inadequate Core Cooling Detection in Boiling Water Reactors", which is also discussed ~in the' Answer to Interro-gatory No. 1. SLI-8218 concluded that if_.the improvements D= to the WLMS identified in SLI-8211 were made and if adequate Emergency Procedures were provided to plant operators, then additional instrumentation to monitor for ICC would not be D warranted. ~

The NRC Staff has designated these issues as Unre-solved Safety Issue A-50, " Reactor Vessel Level Instrumenta-D- tion in BWRs". On October 26, 1984, the NRC issued a Generic Letter .(84-23) to all BWR licensees, which indicated the requirements for resolving this issue. IP fully satisfies D all requirements expressed in this letter.

[4.a. Will an accoustical monitoring system be used at CPS, pursuant to NUREG 0737 II.D.3?

g . .

p

=

[4.b. If so, how will this qualify as a direct

=

monitoring instrument? Provide docu-ments explaining the accoustical monitor-ing system and how it qualifies as a direct monitoring system, if it does.

[4.c. Have any studies been made to assure that reliability and accuracy can be maintained, given specific conditions of BWR, for instance, core vibration that could result in deterioration of devices and/or spurious signals? If so, describe and provide such studies. If not, ex-plain why not.]

n ANSWER: Since the portion of Contention III (formerly Con-tention 6) relating to acoustical monitoring has been with-drawn, Illinois Power will not update its response to this Interrogatory.

T5.a. What plans, if any, exist for providing a safety parameter display system for use in the main control room? Describe

, and explain any such plans.]

ANSWER: A Safety Parameter Display System ("SPDS") is planned for the CPS Control Room. The SPDS requirements, design and funct onal description are contained in the following docu-ments:

Safety Parameter Display System Requirements Document;

Safety Parameter Display System Functional Description; and Safety Parameter Display Design Document (cur-rently being revised).

' iip

The SPDS is befng implemented as a part of the Display Control and Performance Monitoring Systems ("DCS/PMS ")

-11_

m

__ . ,. . ~ , . . . . . . . . . . . . . . . _ . . . . , . -. . . . . ., . , . . . . . -

currently installed in the main control room. The DCS/PMS is the plant processing computer system. The Number 5 cathode ray tube in the NUCLENET (principal plant console) has been designated as the SPDS display.

Implementation of the SPDS display will be accom-plished by the installation of a permanent display in the DCS and an Alarm Initiated Display (" AID"), which will be _

automatically displayed on all nine NUCLENET DCS displays .

when an alarm of any AID parameter occurs. Radioactivity alert is indicated on the Number 5 cathode ray tube with the secondary information available from the Area Radiation Monitor / Process Radiation Monitoring System.

g The SPDS code, which is not complete, will be part of the DCS/PMS software. Detail programming is scheduled _

4 for completion by January '085, with testing and system inte-gration to follow. Flow diagrams for the SPDS modules are g  ;

available in rough draft form for inspection.

[5.b. Provide a list of all meetings of BWR .

Owner's TMI Group and industry contrac-tors where control room design and in- '

O strumentation for CPS was discussed.

Provide the agendas for these meetings, ,

and the documents produced from these meetings.]
