20555 SHOREHAM NUCLEAR POWER STATION - UNIT 1 Construction Permit No. CPPh-95
Dear Mr. Denton:
Pursuant to 10 CFR 5 50.55(b), Long Island Lighting Company requests that the Nuclear Regulatory Commission extend the date for completion of the Shoreham Nuclear Power Station, Unit 1, from December 31, 1980*/to March 31, 1983.
The extension is needed for a number of reasons which include:
1.
New Regulatory Requirements 2.
Evolving Interpretation of Existing Regulatory Requirements 3.
Late Delivery of Equipment 4.
Unexpected Difficulties in Completion of Required Plant Modifications These factors are discussed below:
1.
New Regulatory Requirements
(
As a result of the accident at Three Mile Island and the subsequent investigation of that accident, a significant number of new regulatory requirements have been adopted or are in the process of being adopted.
Accordingly, LILCO has had to factor additional tims into the construction schedule to accommodate:
A.
the time required for the promulgation of final regulatory requirements; B.
the reworking of systems where existing equipment i
must be modified and/or replaced; and l
C.
the design, procurement and installation of new systems and equipment.

Mr. Harold R. Denton November 26, 1980 Re.
Construction Permit No. CPPR-95 Page 2 Significant new requirements include the Technical Support Center (TSC), Post Accident Sampling Facility, and the Emergency Operations Facility (EOF).
Each of these necessitates the modification of existing buildings or the construction of new buildings.
Additional sampling capability and instrumentation are also being developed to meet the functional requirements of these facilities.
- Moreover, these regulatory requirements are still in various stages of development.
2.
Evolving Interpretation of Existing Regulatory Requirements NRC regulations are primarily stated in general terms.
Using all available guidance, LILCO and its contractors designed Shoreham such that, in their judgment, compliance with these general requirements was achieved.
In exercising its review responsibilities the Staff, on occasion, has questioned compliance with the general Commission regulations.
In most instances, LILCO had been able to present sufficient information to resolve these Staff concerns.
In a number of cases, however, LILCO has elected to incorporate modifications requested by the Staff.
An example of such modifications is the addition of a new system for loose parts monitoring.
3.
Late Delivery of Equipment Late delivery of components has continued to cause delays in the completion of Shoreham.
A significant example is the delivery date for the 480 volt LPCI motor generator (MG) sets.
To address the Staff's concerns raised during preparation of the Shoreham SER, MG sets were incorporated in the design of the LPCI system power supplies.
Difficulties in meeting the specifications have caused the vendor's expected delivery date to be delayed from December 1979 until March 1981.
The unavailability of small bore piping valves, orifices, and hanger materials has slowed the completion of piping work in the Main Steam Tunnel.
The absence of this equipment not only delayed completion of the systems for which it is needed, but it also had an adverse impact on the completion of other efforts in the area.
4.
Unexpected Difficulties in Completing Plant Modifications There have been unexpected difficulties in modifying systems to meet regulatory requirements.
For example, system designs within the Main Steam Tunnel were modified to meet NRC pipe whip, jet impingement, and separation criteria which evolved subsequent to the original design effort.
This work has proceeded more slowly than anticipated because of space constraints in the tunnel.
Additionally, the delays in completing the piping systems have resulted in secondary delays in electrical conduit and instrumentation installation as noted above.

o Mr. Harold R. Denton November 26, 1980 Re:
Construction Permit No. CPPR-95 Page 3 Another example of the unexpected difficulties in completing the construction effort is reflected in the motor control centers /
cable / conduit design and installation difficulties resulting from the imposition of final pipe break analysis criteria.
LILCO has, wherever possible, made scheduling and administrative changes to compensate for the unanticipated delays described above.
The net result, however, has been to extend the expected fuel load date.
We reported to the NRC Caseload Forecast Panel in May 1980 that the plant would be ready to load fuel between June and September 1982.
Our current project plans establish a May 31, 1982 fuel load.
Accordingly, and in order to provide a suitable margin for the completion of Shoreham, it is requested that the latest completion date be extended from December 31, 1980 to March 31, 1983.
Very *ruly yours,
