OMAHA PU3LIC POWER DISTRICT Fort Calhoun Station Unit No. 1 March 1980 Monthly Operations Report b I. OPERATIONS SU'UARY Fort Calhoun re=ained in a refueling configuration during the month of March.

Maintenance of systems is continuing. Several refueling surveillance tests were ec=pleted during March. The plant is being placed in a startup configuration while avaiting completion of the I.E. Bulletin 79-02 and 79-lh work.

The special Nuclear Regulatory Com=ission task force on the i=ple=enta-tion of NUP.EG-0578 short ter reco==endations visited the site in early March. No significant proble=s were uncover ed and efforts are continu-ing to co=plete the changes.

One new e=ployee was added to the Operations Department in the position of au: ciliary operator (nuclear) .

The Supervisor-Operations attended a meeting in Windsor, Connecticut to review the E=ergency Procedure guidelines to be sub=itted to the NRC staff frc= the Combustion Engineering owners group.

Other operations duties were performed as scheduled.

A. FIRFORMANCE CHARACTERISTICS LER Nu=ber Deficiency LER-005 An inadvertent radi-active gas release to the atmosphere occurred due to failure of the rupture disk used to protect the reactor con-tain=ent from overpressurization during the Contain=ent Integrated Leak Rate Tes (ILET).

The release was within Technical Specification Limits.

LER-005, Rev. 1 An inadvertent radioactive gas release to the atmosphere occurred due to failure of the rupture disk used to protect the reactor con-tainment frc= overpressurization during the Contain=ent Integrated Leak Rate Test (IIST).

The release was within Technical Specification Limits.

LER-007, Rev. 1 During the review required by I.E. Bulletin (1979)79-013, the ste= =ounted limit switches on-HCV-86h and ECV-865 (charcoal filter spray supply) were found to not be environmentally qualified. The li=it switches provide pcsition indication ouly and vill not jeopardize valve control or cparability.
