MISSED TECHNICAL SPECIFICATION (TS) REQUIRED SURVEILLANCE
Following a reactor shutdown for a planned outage, a TS required surveillance was not met, and an evaluation is being made to determine the reason. Following taking the unit to Hot Shutdown, technical specifications require that procedure SP-2035D, Reactor Protection Logic Testing, be completed prior to making the control rod drive system capable of rod withdrawal. In this case, however, the shutdown reactor trip breakers were closed and the shutdown rods withdrawn. Upon discovery of the missed TS required surveillance, the shutdown rods were inserted, and the trip breakers opened. The required surveillance will be completed prior to re-closing the trip breakers.
The NRC resident inspector will be informed by the licensee.

EMERGENCY SIRENS WERE INADVERTENTLY ACTIVATED DURING TESTING.
AT APPROXIMATELY 2226 MST ON 02/06/99, THE MARICOPA COUNTY SHERIFF'S OFFICE REPORTED TO THE LICENSEE THAT THEIR WEEKLY SILENT TEST OF THE SIREN SYSTEM SHOWED THE SIRENS NOT TO BE FUNCTIONAL. THE LICENSEE, THEREFORE, NOTIFIED THE DEPARTMENT OF PUBLIC SAFETY TO REQUEST THAT THEY TEST THE SIREN SYSTEM FROM THEIR ALTERNATE LOCATION. DUE TO A COMMUNICATIONS MISUNDERSTANDING, THE DEPARTMENT OF PUBLIC SAFETY TESTED THE SIRENS BY ACTUALLY RUNNING THEM FOR APPROXIMATELY 77 SECONDS. ALL 39 SIRENS WERE DEMONSTRATED TO BE FUNCTIONAL. AS A RESULT OF THE SIREN ACTUATION, THE LICENSEE HAS HAD FOLLOW-UP COMMUNICATIONS WITH MARICOPA COUNTY DEPARTMENT OF EMERGENCY MANAGEMENT. ALTHOUGH THERE WERE SOME CONCERNS FROM RESIDENTS IN THE AREA, NO PRESS RELEASE IS PLANNED.
THE NRC RESIDENT INSPECTOR WAS NOTIFIED ALONG WITH STATE AND OTHER GOVERNMENT AGENCIES.
