The Power Authority will survey the capability of the existing IP3 fixed and portable instrumentation to Inonitor the course of accidents that extend beyond conditions asstrned in the design of the plant. This survey will be provided to the NRC by July 9, 1979.

4. Audit of the plant's capability for safe shut-down and residual heat renoval, using only safety grade equipnent.

'Ihe Power Authority will participate in the NRC's Overall Plant Heat Removal Capability Survey to be conducted at the IP3 facility on November 14 15 & 16, 1978.

5. Continuing effort be made to update safety related features to the maximum degree possible.

The Power Authority will provide docunentation of the extent to which the IP3 facility satisfies the ACRS resolved generic items as delineated in their Report No. 6 to the NBC. This information will be provided to the NRC by February 19, 1979.
