$'cM D Intervenor contends Applicant's main generator turbine is not designed sufficiently to prevent turbine missiles O  %

(bl l 125 from damaging critical components of the system. Further,

( that stoppage or vibration of the turbine following missile thrust will create. dangerous halting and" damage to the tur-bine5and main steam power train of the plant.

That one turbine has indeed e:cpelled a portion oft alttirbine disic is shown by Board Motification SN 80-8, which sites a ore-liminary report of a portion of a disc hurled during;turbi'ne synch-ronization at (800 rpm on Feb. 14, 1980, at the Yankee Ryge, nuclear plant in Massachusetsa. Crac'cing of turbine disks is the subject of Board IIotification BU 80-4, which indicates "the cracking may be core widesfWdad than previously reported" and that one manufacturer, Westinghouse,is, " (ij n the process of elevating some of their previously estimated turbine missile onergies". ( BU 80-4; Janury '6,1980). The largest cracks d.e-tected to date were found at Zion Station. Unit 1 , and re7arted _

Suo'orting Statenent for Contention #47 This Intervanor believes, the above Contention should be admitted to the proceedings because

a. There was far less basis to argue the Contrations admissibility at the original deadline, because the Yankee Rowe incident had not occured. In~short the Contention is currently based on new evidence.

b. No other party has raised the issue. There are no current plans to consider the issue at this moment within the NRC.

c. Consideration of the issue in regard to the large turbine to be used at ACNGS will develope an important part of the record. At this moment, it appears most of the turbines involved in the ordered inspections and incidents such as Shioningoort, 1974, are much smaller than AC:!GS.

d. No e::isting '2rty has indicated an interest in this issue to date.

g

e. It does not appear the issue will unreasonably delay thes e oroceedings. The issue is a well focused one which is unlikel7 to broaden the proceedings greatly.
