Operational Safety Verification (71707, 92700)
i The inspectors conducted routine plant tours during this inspection period i
to verify that the licensee's requirements and commitments were being
implemented. These tours were performed to verify that: systems, valves, and breakers required for safe plant operations were in their correct
,
position; fire protection equipment, spare equipment and materials were
being maintained and stored properly; plant operators were aware of the current plant status; plant operations personnel were documenting the status of out-of-service equipment; security and health physics controls were being implemented as required by procedures; there were no undocumented cases of unusual fluid leaks, piping vibration, abnormal hanger or seismic restraint movements; all reviewed equioment requiring calibration was current; and general housekeeping was satisfactory.

Tours of the plant included review of site documentation and interviews with plant personnel. The inspectors reviewed the control room operators'
logs, tag out logs, chemistry and health physics logs, and c:ntrol board:
and panels.
During these tours the inspectors noted that the operators
<
ar9 eared to be alert, aware of changing plant conditions and manipulated piant controls properly.
The inspectors evaluated operations shift
,
turnovers and attended shift briefings. They observed that the briefings
and turnovers provided sufficient detail for the next shift crew and verified that the staffing met the TS requirements.
i Sito security was evaluated by observing personnel in the protected and vital areas to ensure that these persons had the proper authorization to be in the respective areas. The inspectors also verified that vital area portals were kept locked and alarmed. The security personnel appeared to be alert and attentive to their duties and those efficers performing
'
personnel and vehicular searches were thorough and systematic. Resperses to security alarm conditions appeared to be prompt and adequate.

Selected activities of the licensee's Radiological Protection Program
)
were reviewed by the inspectors to verify conformance with plant procedures and NRC regulatory requirement.
The areas reviewed included:
operation and management of the plant's health physics staff, "ALARA" l
implementation, Radiation Work Permits (RWPs) for compliance to plant
'
procedures, personnel exposure records, observation of work and personnel in radiation areas to verify compliance to radiation protection procedures, and control of radioactive materials.
No discrepancies were

noten.
On October 21 while operating at 100% reactor power a Unit 1 reactor trip occurred.
The trip was reported to the NRC in accordan:e with 10 CFR 50.72, 10 CFR 50.73 and site administrative procedure FNP-0-AP-16 Conduct of Operation. The licensee has documented the event and is evaluating the facts and circumstances surrounding the trip.
The inspectcrs reviewed the preliminary Licensee Event Report data, interviewed responsible operations and maintenance personnel and noted the following:
Reactor trip occurred after the main turbine throttle valves closed.

i Throttle valves closed while maintenance personnel were conducting
maintenance activities on the main turbine over-speed protection

computer circuit.
!
Maintenance activities were non-safety related and were authorized by maintenance work request MWR 186751.
'
Authorized maintenance activities required a test card to be inserted
,
i into the turbine speed control card rack. Records indicate that when
'
l this occurred a voltage drop or erroneous data was injected into the

l
computer's universal input output buss.
This resulted in a signal being generated to cause the turbine main throttle valves to close.
When maintenance personnel re-enacted the work functions which preceded the turbine trip, they discovered that the test card had a switch located near the outer front edge of the card.
If the card was grasped in the mid front position while inserting, it is likely that the test switch could have been momentarily re positioned. An analysis of the speed control circuitry indicates that momentarily flipping this test switch to the "simulate" position while pushing the card into place could cause a false trip signal to be injected into the speed control circuit.
Following the reactor trip all of the required equipment started and the plant was maintained in a safe shutdown condition until the cause of the trip was 6.sessed by operations personnel.
The plant was returned to power operation on October 22.
The inspectors have reviewed the licensee's evaluation of this trip and have no further questions at this time.
The inspectors reviewed the medical records of two shift supervisors and four reactor operators which have an NRC senior reactor operator or reactor operator license. The scope of this audit was to verify that the medical examinations satisfied the requirement of 10 CFR 55 and that each operator's medical records were up to date. Of the records reviewed no discrepancies were identified.
On October 19 Unit 2 experienced excessive vibration on the butterfly valve which is used for isolating the service water flow through the 2C component cooling water heat exchanger. A maintenance work request
'MWR-185161) was initiated to authorize the necessary maintenance to repair the valve.
Maintenance personnel inspected the operator on the valve (Q2p16V0007C) and found the lever to be worn and the pin located in the thrust collar was sheared. Authorized repairs were made, the valve operator was tested and the valve was returned to service.
3.
Monthly Surveillance Observation (61726)
The inspectors witnessed the licensee conducting maintenance surveillance test activities on safety related systems and components to verify that the licensee performed the activities in accordance with TS and licensee requirements. Those observations included witnessing selected portions of each surveillance, review of the surveillance procedures to ensure that administrative controls and tagging procedures were in force, determining that approval was obtained prior to conducting the surveillance test and the individuals conducting the test were qualified in accordance with plant-approved procedures. Other observations included ascertaining that test instrumentation used was calibrated, data collected was within the

Information Meeting With Local Officials (94600)
On October 14 the inspectors visited and met the staff of the Houston County Emergency Management Ager.cy in Dothan, Alabama.
A brief description of the NRC organization and its relationship to the operation of the Farley Plant was given to the Emergency Management Agency staff.
The inspectors also toured the Emergency Operations Complex.
The meeting was beneficial in that the resident inspectors learned more about the organization and function of the Emergency Management Agency and were able to provide information about the NRC's normal responsibilities and duties in the event of an emergency.

Emergency Exercise of 1988 (82301)
The resident inspectors participated as team members in the NRC evaluation of the Farley Emergency Exercise which was conducted on November 2,1988.
The 1988 Emergency Exercise consisted of a simulated seismic event which caused a loss of the
"A" train emergency 4160V buses.
The loss of electrical power in conjunction with initial charging pump and CCW pump configuration resulted in a loss of RCP seal cooling.
Fif teen minutes
!
after the seismic event, the RCP seals failed causing a loss of reactor l
coolant accident and an Alert classification. An aftershock at 9:15 a.m.
t resulted in a CROM rupture and subsequent declaration of a Site Area Emergency.
At 10:30 a.m. another af tershock lead to the failure of the personnel hatch and leakage from containment to the environment.
On November 2 at approximately 2:50 p.m. during the annual emergency drill the off-site emergency notification sirens at Ashford, Columbia and Gordon were found to be inoperative.
Investigation by the Houston (Alabama)
Emergency Management Agency found that the main actuation panel would not actuate the sirens by using the normal actuation devise.
Temporary
,
repairs were made to the system at 4:45 p.m. on November 2 which permitted I
the system to be operational. Final repairs were completed on November 3 at 11:00 a.m, and the system was fully restored and returned to service.
The system was subsequently tested satisfactorily on November 9.
