Subject:
System 80+5 Intersystem Loss of Coolant Accident (ISLOCA)
Dear Sirs:
r Attached is the ABB-CE report presenting the evaluation of the System 80+ design in response to ISLOCA events.
There were some improvements identified to the 1
System 80+ design as a result of this evaluation. The improvements to the System 80+ design include:
3j ll' 1.
Increasing the design pressure of some equipment and some systems, 2.
Adding equipment and instrumentation which terminate and limit the scope of-an ISLOCA, and 3,
Changing system interface' locations.
The System 80+ design with the improvements stated in the' report complies with,
[
~
the SECY-90-016 recommendations.
The evaluation was conducted by. ' defining an ISLOCA as an event, which occurs outside containment in a system connected to the t
RCS and results in a loss of primary system inventory. The event is assumed to l
be caused by the inadvertent opening of RC's isolation valves or the failure to close of RCS isolation check valves. This assumption was made because various studies have indicated that the more likely ISLOCA precursors would be initiated
{
by human errors or procedural deficiencies.
The acceptance criteria were established to demonstrate that:
1.
The system retains its structural integrity throughout the event, 2.
Any leakage caused by the event would be limited tio the makeup system capabilities, and 3.
Offsite doses are limited to a small fraction of those in 10 CFR100.

3 In conclusion, the design pressure for systems interfacing with the RCS was generally shown to be at least 40% of normal RCS operating pressure.
Where it was impractical to increase the design of the interfacing systems, a
justification for - alternate solutions was made.
The justification included complexity issues, use of first of a kind systems, hardware and installation, and the need for additional unproven systems.
