DECADE'S ANSWER TO LICENSEE'S MOTION FOR INTERIM OPERATION OF UNIT 1 WITH STEAM GENERATOR TUBES JLEEVED RATHER THAN PLUGGED Intervenor Wisconsin's Environmental Decade, Inc.(" Decade")
makes this answer, pursuant to 10 C.F.R. 5 2.7 3 0 (c),
to the Licensee's Motion f or Authorization f or Interim Operation of Unit 1 With Steam Generator Tubes Sleeved Rather Than Plugged,"
dated September 28, 1981(" Motion").
The Decade is it: opposition to the Motion for the reasons set forth herein.
It has been established by reputable, independent scientists that the rupture of between one and ten steam generator tubes in the course of a loss of coolant accident could cause esscatially uncoolable conditions in tiie reactor.
Report to the American Physical Society by the Study Group on. Light Water Reactor Saf ety, 47 RevieH Rf Modern Physics, Supp.1, Summer 1975, at S85 - S91.
It is also known that controlled laboratory tests of the j
sleeving process reduces the'ctrength of the original tube by approximately 10% it the point where the top of the sleeve is 8110070313 011004 09 PDR ADOCK 05000266 99 9 0\\

+t i
T welded or brazed to the inside of the tube.
Obviously, field experience with sleeving may result in significantly greater reductions.
At this juncture, unfortunately, the record does not contain suff>cient information to make any determination on the extent of this reduction in strength in the field.
This means that, were Unit 1 permitted to return to service following the " demonstration" sleeving of "up to 12 tubes" a serious without a f ull hearing on the issues in contention, safety pr.oblem may be created.
That is to say, the fact the only a few tubes are alleged to be the subject of the " demonstration" program does not in any way imply that major issues are not at issue, because the inopportune rupture of only one tube weakened by the welding or brazing process brings the APS conces.,n into play.
At the same time that premature approval based upon incomplete information raises grave safety issues, virtually no reasons have been given by the Licensee why 12 sleeved tubes must be returned to service without plugs prior to completion of this proceeding.
. For the foregoing reasons, the Motion should be denied.
