  • APPLICANTS' SECOND SET OF INTERROGATORIE /

ACORN AND REQUESTS TO PRODUCE %g Pursuant to 10 C.F.R. $$2.740b and 2.741, Texas Utilities Generating Company, et al. (" Applicants") hereby

, serve Applicants' Second Set of Interrogatories and Requests to Produce upon Texas Association of Community Organizations for Reform Now (" ACORN"). Each interrogatory shall be answered fully in writing, under oath or affirmation, and include all pertinent information known to ACORN, its offi-cers, directors os; members as well as any pertinent in forma-tion known to its employees, advisors or ::ounsel. Each request to produce applies to pertinent documents which are in the possession, custody or control of ACORN, its officers, directors or members as well as its employees, advisors or counsel. In answering each interrogatory and in responding b 5033 to each request, please recite the interrogatory or request I

8.103050 M 6 -

preceeding each answer or response. Also, please identify the person providing each answer or response.1!

These interrogatories and requests shall be continuing in nature. Thus, any time ACORN obtains information which renders any previous response in* correct or indicates that a response was incorrect when made, ACORN should supplement its previous response to the appropriate interrogatory or request to produce. ACORN should also supplement its responses as necessary with respect to identification of each person expected to be called at the hearing as an expert witness, the subject matter of his or her testimony, and the substance of that testimony. The term " documents" shall include any writ-ings, drawings, graphs, charts, photographs, and other data compila-icns from which information can be obtained. We request that at a date or dates to be agreed upon, ACORN make available for inspection and copying, all documents subject to the requests set for ch celow.

APPLICANTS' INTERROGATORIES AND REQUEST TO PRODUCE Contention 10: The CPSES design fails to adequately account for the effect of asymmetric loading resulting from a pipe break in the areas between the reactor vessel and the shield wall.

-1/ The instant discovery requests directed to ACORN concern Contentions 10, 12 and 14 for which ACORN is lead-party Intervenor. If, however, any other Intervenor possesses information or documents requested herein which ACORN intends to use in support of its position on these con-tentions, such information or documents should be provided in response to these interrogatories and requests to produce.
