I TMIA'S RESPONSE TO LICENSEE'S SECOND SET OF INTERROGATORIES AND REQUEST FOR PRODUCTION OF DOCUMENTS Three Mile Island Alert (TMIA) hereby submits its responses to General Public Utilities' (Licensee ' .;) reque.:t for production of documents and interrogatories.

from the out.:e t it is crucial to note and the Board is well aware that requests for technical assistance are before the Board and are necessary to insure fairness and discovery of the absolute truth in redard to the steam tube integrity.

Furthermore, the intervenor is severly hampered by the action of the licensee which serves to limit the response which intervenor can forward. For example on February 16, 1984 fifteen documents were delivered to TMIA and as late as February 17, 1984 another document was delivered. These documents are crucial and necessary for the development of TMIA's response, but due to lack of qualified experts and the fashion in which the documents arrived TMIA's response is brief.1

l. (See TMIA Motion for Appointment of Special Panel, January 25, 1984) TMIA currently has a motion before the ASLB that requests a panel of experts be appointed that would insure a competent and expeditious evaluation of the safety of the steam tube repairs.

I nterroga t or ios i. .--

II-1.a-l. For each " post repair and plant performing testing and analysis" which you have identified as inadequate in your response to Interrogatory 1.a-1 under Part I of this document, do you allege that such test or analysis was inade-quate in its assessment of:

(a) The fatigue life of the TMI-1 steam generator tubes before kinetic expansion repairs were performed and/or after kinetic expansion repairs were performed; (b) The stress levels on the TMI-1 steam generator 1

tubes before kinetic expansion repairs were performed and/or j after kinetic expar-sion repairs were performed; (c) the effects of the corrosive contaminant on the

. stress le"als on the TMI-3 steam generator tubes, and the fa-i tigue life of TMI-1 steam generator tubes; (d) the effects of changed strength and dimensions of tubes which have been kinetically expanded on the stress levels on the TMI-1 steam generator tubes and the fatigue life of the TMI-l steam generators; _ _ _ _ , , _ _ _ _ _ _ _ _ _

(e)~~The crack size, for purposes of determining the stress levels on the TMI-1 steam generator tubes, in particular the effects of thermal stress, and the fatigue life of TMI-1 steam generator tubes; and (f) The crack location, for purposes of determining the stress levels on the TMI-1 steam generator tubes and the fatigue life of TMI-l steam generator tubes?

Responses At this time TMIA does not have access to the technical expertise which would allow TMIA to assess the adequtcy of licensee's testing and analysis.

II-1.a-6. If your answer to Interrogatory II-1.a-5 above is other than an unqualified "no", explain why it was improper to use that axial l_oad during the corrosion tests.

II-1.a-7. State in detail each and every fact upon which you base your allegations in your answer to Interrogatory II-1.a-6.

II-1.a-8. Explain in detail how each fact stated in your answer to Interrogatory II-1.a-7 supports your allegations in Interrogatory II-1.a-6.

II-1.a-9. Identify each and every document which you claim supports each fact set forth in your answer to Interrogatories II-1.a-5 through II-1.a-8 above, and correlate i' each such document as specifically as possible (page and para-graph number) with each such fact.

Response to II-l.a-2 through II-1.a-9:

At this time TMIA does not have access to the technical expertise which would allow TMIA to identify the inadequacies of Licensee's testing and analysis.

II-1.b-1. Explain how the alleged " history of affecting other primary pressure boundary materials" of the corrosion damage affects the likelihood of a simultaneous tube rupture in both steam generators.

II-1.b-2. State in detail each and every fact upon which you base your allegatione in your response to Interrogatory II-1.b-1, and explain in detail how each such fact supports the allegation.

II-1.b-3. Identify each and every document which you claim supports each fact set forth in your answers to C

Interrogatories II-1.b-1 and II-1.b-2, and correlate each such document as specifically as possible (page and paragraph number) with each such fact.

Response to II-1.b-1 throuqh II-1.b-3:

At this time TMIA does not have access to the technical expertise which would allow TMIA to identify how the history of affecting i

other primary pressure boundary materials of the corrosion damage will affect the likelihood of a simultaneous tube rupture in both steam generators.

II-1.b-4. Explain how the alleged " uniqueness and 1

! deforming character of the repair method'used" affects the I

likelihood of a simultaneous tube rupture in both steam genera-tors.

l-l II-1.b-5. State in detail each and every fact upon which I

you base your allegations in your response to Interrogatory II-1.b-4, and explain in detail how each such fact supports your allegation,

5.

II-1.b-6. Identify each and every document which you claim supports each fact set forth in your answers to Interrogatories II-1.b-4 and II-1.b-5, and correlate each such document as specifically as possible (page and paragraph number) with each such fact.

Response to 1I-1.b-4. through 11-1.b-6 Page 15 of TPR states: "The explosive expansion of the tubes could affect the stress levels if the process would change the strength or some dimension of the tubes." Since all of the tubes in both S .G 's uriderwent the expansion repinir process, there is a greater probability of simultaneous tube rupture at TMI-1.

II-1.b-7. Explain how the "large number of tubes which were repaired" affects the likelihood of a simultaneous tube rupture in both steam generators.

II-1.b-8. State in detail each and every fact upon which you base your allegations in your response

  • o Interrogatory II-1.b-7, and explain in detail how each such fact supports your allegation.

II-1.b-9. Identify each and every document which you claim supports each fact set forth in your answers to Interrogatories II-1.b-7 and II-1.b-8, and correlate each such document as specifically as possible (page and paragraph number) with each such fact.

See response to II-1.b-4 through II-1.b-6.

h, II-1.b-lO. Explain your understanding of the Commission's May 5, 1983 response to Congressman Markey discussing the Shewmon Memor andum, and how that May5, 1983 response affects your contention that the Shewmon Memorandum supports Contention 1.b.

R es ponse : The Commission's May 5, 1983 response to Congressman Markey appears to assure Congressman Markey that a simultaneous tube rupture in both S.G 's is unlikely. However these assurances are not supported with any data and in some instances contradict the position of the Staff in other documents, i.e. at page 2 the response relies on ECT as a method of early detection of leaks, but in a May 19, 1982 memorandum, the Staff indicates that ECT is unpredictable as a method of detecting and quantifying the type of corrosion found in TMI-1 OSTG.

II-1.b.11 Explain how Licensee's TDR-406 section 2.1.3.1 provides support for the possibility of simultaneous tube rupture in both steam generators.

Res ponse: TDR-406 deals with technical guidelines for dealing with tube ruptures. Section 3.1.1 has a provision to deal with tube leaks in both OSTG's. The " Comments" at p.21 of the TDR indicate that operators who were being trained on the use of the revised guidelines found the training to be of " dubious value" and that B&W would not endorse the material.

II-1.bl2 State in detail each and every fact upon which you base your allegations in your response to Interrogatory II-1.b.11 and explain in detail how each fact supports your allegations.

Ihsponse See response to interrogatory II-1.b.11.

II-1.b-14. State in detail each and every fact upon which you base your allegations in your response to Interrogatory II-1.b-13, and explain in detail how each such fact supports your allegations.

. . '7, gesponse to II- 1.b-13 and II-1.b-14:

Page 4 of the TPR indicates that to ensure the safety of the plant it is necessary to canplete an analysis of the contingency of multiple tube rupture and to translate that analysis into useable plant guidance, 1

procedures and training. However the "Coments" at page 21 of TDR-406 indicate that the information has not been translated into useable

plant guidance.

II-1.b-15. Explain how SECY-82-72 dated February 18, I

1982, pages 2 to 3, supports Contention 1.b.

II-1.b-16. State in detail each and every fact upon which you base your allegations in response to Interrogatory II-1.b-15, and explain in detail how each such fact supports 1'

your allegation.

II-1.b-17. Identify each and every document which you claim supports each fact set forth in your answers to R es ponse SECY-82-72 discusses the overall steam generator problem and points out a concern with simultaneous steam generator rupture.

Page 2 of the document in particular, discusses the continuing loss of core cooling ability and the significant challenge to plant operators and sa(ety systems.

II-1.c-1. Do you allege that the kinetic expansion repair weakened the tubes such that plugs will not be able to hold and give a good seal?

II-1.c-2. If the answer to the preceding Interrogatory is other than an unqualified "no": .

(a) Identify each type of plug which you allege will not be able to hold and give a good seal; (b) State in detail each and every fact upon which you base your allegation that each such type of plug will not be able to hold and give a good seal; and i

II-1.c-3. Identify each and every document which you claim supports each fact set forth in your answers to Interrogatories II-1.c-1 and II-1.c-2 above, and correlate each such document as specifically as possible (page and paragraph number) with each such fact.

II-1.c-4. Define and explain the extent to which you allege a plug must be able to " hold."

II-1.c-5. Define and explain the extent to which you allege a plug must be able to "give a good seal." Include in your answer your definition of a " good seal."

II-1.c-6. Provide the factual, legal, and regulatory basis for your responses to Interrogatories II-1.c-4 and II-].c-5 above.

II-1.c-7. Identify each and every document which you claim supports each fact set forth in your answers to Interrogatories II-1.c-4 through II-1.c-6 above, and correlate each such document as specifically as possible (page and para-graph number) with each such fact.

Response to II-1.c-1 through II-1.c-7:

At this time TMIA does not have access to the technical expertise which would allow TMIA to recognise the degree to which the expanded tubes have lost their plug holding capability.

II-1.d-1. What do you mean by "any independent anal: sis" which you allege appears not to have been done by either the Yhird Party Review Group or the NRC Staf f?

Response: Independant analysis means in this instance analysis other than that performed by GPU or its consultants. Both the SER and the TPR rely on GPU testing and analysis in reaching their conclusions.

'\ .

II-1.d-2. If no independent analyses (as defined in your answer to Interrogatory.II-1.d-1) was performed by either the Third Party Review Group or the NRC Staff, do you allege that this fact renders the " Report of Third Party Review of Three Mile Island, Unit 1, Steam Generator Repair ("TPR") or the Staff's Safety Evaluation Report ("SER") incredible documents in their evaluation of "the kinetic expansion repair technique including leak tightness and load carrying capabilities"?
