Subject:
Three Mile Island Short Term Lessons Learned Show Cause Order R.E. Ginna Nuclear Power Plant Docket 50-244
Dear Mr. Denton:
An order dated January 2,
1980 required, in effect, that we show cause why we should not. by January 31, 1980 implement. all "Category A" short term lessons learned requirements except, those for which necessary equipment is unavailable, or maintain Ginna in a cold shutdown or refueling mode of operation.
We hive previously submitted the required information and conversations with you and members of your staff have indicated that our imple-mentation of the requirements is acceptable.
The information specifically required to address the Show Cause Order is repeated here.
Our letters of October 17,'979, November 19,
- 1979, December 13, 1979 and December 28, 1979 described our intentions to comply with the short term lessons learned requirements and documented our methods of compliance.
All of the category A
requirements except item 2.1.4, Containment Isolation, have been implemented.
The existing containment. isolation system conforms with the diversity requirements of the staff position and automatically isolates all non'essential systems not, already isolated.
There are some valves,
- however, which could reopen upon reset of the containment isolation or containment ventilation isolation signals if their controllers were set for the open position.
A system modification has been designed which will provide for individual resetting of all isolation valves to eliminate the possibility of an inadvertent opening following reset.
Until this modification is installed, the reopening of the valves is precluded and an equivalent level of safety is provided by alternative means.
First,RD~~
the operator has been directed to place all isolation valve posi-tion controllers in the closed position so that no valve will open ]/y H. QFhfT~ ) 0 SOOZSOO
ROCHESTER GAS AND ELECTRIC COR QATE January 16, 1980 To Mr. Harold R. Denton, Director SHEET HO.
on initiation of reset.
Reset of containment ventilation isola-tion and containment isolation can be actuated only through the use of key switches.
Keys are under the control of the Shift Supervisor.
Therefore, no single operator error can result in improper use of the reset. function.
The modification requires installation of four relay cabinets containing over 190 relays and two panels with 50 pushbuttons each.
The equipment is being manufactured by Electro-Mechanics, Incorporated of New Britain, Connecticut.
Our order (N-EZ-03445) was placed with them on November 26,
- 1979, however, work was formally initiated on the modification by Rochester Gas and Electric Corporation on August.24, 1979 with the issuance of an Engineering Work Request.
Work that was performed between August and November included systems analysis to define and scope the modification, conceptual
- design, design review and choice of system
- approach, basic system design, review of vendor capabilities, equipment description and specification preparation, proposal preparation and review and vendor selection.
Electro-Mechanics is performing some of the detailed design and the fabrication of the equipment.
Delivery of the equipment has been quoted as twenty-two weeks after receipt of order.
We are attempting to expedite the delivery wherever possible, however receipt of materials from subvendors largely determines the delivery date.
Electro-Mechanics has been instructed to use premium time whenever it will result in a schedule improvement.
Equipment delivery from Electro-Mechanics is expected in early May, 1980.
We plan to install the equipment within 30 days of receipt, but no later than June 1,
1980.
Installation of the equipment requires a plant outage and is estimated to take approximately three weeks.
Some of the work can be performed prior to equipment delivery to prepare for the'abinet installa-tion and testing if the plant is shutdown.
The above information plus the address and telephone number of Electro-Mechanics were provided to a member of your staff on January 8,
1980.
This letter, provides appropriate and timely justification for continued operation of the R.E. Ginna Nuclear Power Plant.
Equipment necessary for mechanical modifications to meet the
