10 CFR 50.59, " Changes, tests and experiments," permits the licensee to make changes to the facility and procedures as described in the safety analysis report and conduct tests or experiments not described in the safety analysis report without.

prior Commission approval provided the change does not involve a change in the technical specifications or an Unteviewed Safety Question (USO). The licensee shall maintain records of changes in the facility and these records must include a written safety evaluation which provides the bases for the determination that the change does not involve a USQ.

10 CFR 50.9(a) requires, in part, that information provided to the NRC by a licer'see or information required by regulation to be maintained by a licensee shall be complete and accurate in all material respects.-

UFSAR Section 5.2.5.1, " Reactor Cavity and Containment Floor Drain Sumps,"

Figure 5.2 3 specified that a vendor bar grate of approximately 5 inches was to be installed over each of the containment floor drains.

Contrary to the above, as of March 14,1997, the facility was not as described in the UFSAR in that the grates described in UFSAR Figure 5.2 3 covering the containment floor drains leading to the containment floor drain leak detection system were not installed. The drains were either covered with a different grate or screen, or were not covered at all resulting in the potential that foreign material could enter the drain system and adversely affect the leak detection system. A written safety evaluation was not performed to make a determination that the change did not involve an unroviewed safety question in addition, the updated FSAR was not complete and accurate in all material respects in that it did not reflect this change.

This is a Severity Level IV violation (Supplement 1).

Pursuant to the provisions of 10 CFR 2.201; Commonwealth Edison Company (Licensee) is hereby required to submit a written statement or explanation tn the U.S. Nuclear Regulatory Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a copy to the Regional Administrator, Region Ill, and a copy to the NRC Resident inspector at
