(La Crosse Boiling Water Reactor) )

l TNTERVRNGR'S RESP 0i;3R TO APPLTCANT'S TNTRRROGATORTES Pursuant to 10 CPR 2 740(b), the Coulee Region Energy Coalition, Intervenor in Dairyland Power Cooperative's application for an Amendment to Provisional Operating Licence DPR-45, hereby submits the following answers in response to Applicant Dairyland Power Cooperative's Interrrogatories:

1.

Individuals who contributed to the answering of these interrogatories have submitted affidavits which are enclosed.

2 We have at present no expert witnesses who have agreed to testify at the hearings.

3 CREC cons tders Applicant's discussion of the spen t fuel storage pool components listed in Intervonor's interrogatories P

r.;

be highly deficient.

CREC lacks at present the professional back-V; g(

ground necessary to describe specific mechanisms or proc sses by

>a.,

?,, which this component would experience degradation.

CREC maintnins i

$"i that it is Applicant's responsibility to research and present a well-

[i formulated discussion of this topic.

j, 4.

CREC feels that Applicant has satis factorily answc red

]

p interrogatories 2-1 and 2-2 with regard to structural, mechanical,

<. '. physical and other impacts.

5 CREC is not sufficiently conversant with specific monito'r,

ing methods to identify defective fuel elements.

CREC presumes fu ture.., -

monitoring methods will not substantially differ from those now e

employed f,r 'the reactor.

Due to the fact that the periods of time for storagage are to be considerably longer than.those for which industry experience has provided no evidence of "significant" s.

degradation, CREC questions whether " general monitoring techniques will prove to be sufficient.

6.

It is CREC's belief that Applicant should visually l

monitor failed fuel assemblies on a periodic, known schedule, and that regular "crosscheck" monitoring of all assemblies by' independent, E recognized experts be established as routine procedure.

7.

CREC has no information on methods for encapsulating

,'f defective spent fuel assemblies, other than a reference to "a special container", provided on page 8 of the Answers to Interrogatory 2-6.

CREC requests further information on these heretofore unmenti oned "special containers", including purchasing and installation costs.

8.

CREC has no information at this time from which to develop a clear correlation between crud and corrosion.

Applicant's answer of 2-11 (a) seems, however, to support CRE",'s belief that crud does increase the corrosion rate.

Crec requests fiCures to substantiate Applicant's answer that this increase is " negligible".

9.

According to Dairyland power documents presented in ACRS f

hearings of January,,1978, pieces of fuel rod were lost during transfer.

Applicant has neither satisfactorily discussed the prospects for similar incidents in the future, nor discussed the ramifications of repeated incidents such as these. CREC requests further information of this topic.
