In the Matter of CENEEAL RJBLIC UTILITIES Locket No. 50-289 (Three Mile Island Nuclear (Steam Generator i epars)

licensee to proceed with pre-critical (non-nuclear hot functional testin6),
is unacceptable and threatens the health and safety of the public.
In view of the testimony rendered by the Commissioners before the Committee on Interior & Insular Affairs, House of I epresentatives (4-26-83 Pg. 35) Carefull attention should be applied to this subject.
Seiberling.
How did sulfur get in the system?
Palladino.
Well, the spray system has sodium thiosulphate in it.
The punps used in that system are also used to mix the borated water systen.
Somehow there was leakage fior.e one system to another that got into the borated water tank and some of that was inadvertently introduced into the systern somewhere along the line.

"his could happen to E&W reactors?
palladino.
Yes I think there were three reactors that used sodium thiosulphate Palladino.
GPU has investigatalall the parts of this system incluling lifting the head and making examinations en other inte;;.11 parts that might have been sindlarly affected, and to the b+.g3; cf my knowledge, no impact on other compenentn was noted.
In view of the Commissioner's uncertain testimony about the introduction of thiosulphate into the coolant systen(how & why) and the dependence on GFU's veracity on the investigation about the int:eGrity of the metal-lurgical chatacteristic of internals parts contaminated by thiosulphate, a vigorous objection is made to het f unctional testing prior to a hearin6 After all, does the aviation industry attempt to put winrr on a plane while it's in fli ht?
6 Licensee's arguments to pursue hot functional testing obscures the seriousness of the expansion tube process, which is in doubt and denies standard engineerin6 procedures.
Because of earlier radioactive contamination to the coolant system and a threat to additional fracturing when pressure is applied, the need for indepth analysis by outside professionals is absolutely essential to protect the health and safety of off site residents.
Without safe reassurances, via a public hearing, to establish engineering compliance procedures, a real threat remains that detrite laboratory pipe-section testing by GPU, Unit 1 could encounter seve c damage alon6 with substantial off-site radioactive releases.
The Commission should keep in mind that discovery of past indiscretions conmittted by GPU were brought to light by the public hearing process nct by GFU's voluntary endeavors.

i For the reasort set forth we request that the Board weigh the safety issues involved a6ainst GPU's mana6ement intregrity, CPU's mnacenent responsibility for introducing thicculphate into the primazj system (inadvertently or not) and management's past performance before allowing hot functiowl.. testing.
A reasonable and " safe" alternative is to requi:e total replace-hent of the steam generaf.or tubes and all vital functioning
