I Work continued.on improvement modifications to the Plant Security and Fire Protection Systens.

Work continued <nt modifications to the Control / Auxiliary Building walls i

to improve seismic integrity.

s Work continued on TMI-related modification work.

}

Work' completed on the 2 and 5 yr. maintenance' and inspection of the diesel fire pump and driver.
