| 2. Division II Diesel Generator Operability Failure Review
| |
| This inspection was conducted by the SRI to review the conditions and
| |
| actions which led to a Division II diesel generator operability failure on
| |
| March 17, 1986, and to review the planned corrective actions. During
| |
| l performance of Surveillance Test STP-309-0202, " Division II Diesel
| |
| Operability Test," on March 17, 1986, the diesel started and came up to
| |
| speed, frequency, and voltage within the required time, but about one
| |
| minute later it began to coast down and stopped because of loss of fuel
| |
| ;
| |
| oil flow. River Bend Technical Specifications requires the diesel to
| |
| operate loaded for at least 60 minutes for demonstration of operability

| |
| and requires three separate and independent diesel generators (1A,1B, and
| |
| IC) to be "0PERABLE" in "0PERATIONAL CONDITIONS 1, 2, and 3." The plant
| |
| was in operational Condition 1 on March 17, 1986. The licensee
| |
| immediately initiated a condition report (86-0311) for investigation,
| |
| analysis and corrective action on the ailed operability test.
| |
| The SRI review of the licensee's investigation of this incident revealed
| |
| the following:
| |
| a. Inadequate Corrective Action: A similar event occurred on February
| |
| 14, 1986, when the Division I diesel generator (1A) failed the
| |
| surveillance operability test. The condition report (86-0179)
| |
| investigation for this failure revealed that the fuel oil strainer
| |
| valve handle was missing and that the strainer valve was misaligned
| |
| causing a loss of fuel oil flow to the diesel generator. The Nuclear
| |
| Plant Engineering (HUPE) documented corrective action on February 15,
| |
| 1986, only required that the fuel oil strainer valve be realigned and
| |
| that successful operation of the diesel be demonstrated. No ger.eric
| |
| action to prevent recurrence was documented, and no remedial or
| |
| generic corrective action was specified to be implemented by any.
| |
| Other section or department. No reason was determined for the
| |
| missing handle or for the misalignment of the fuel strainer. Also,
| |
| the investigation did not determine the duration of time that the
| |
| fuel strainer had been misaligned. The analysis and understanding of
| |
| the adverse condition does not appear to have been thorough enough to
| |
| identify and correct the root cause of the problem. This is
| |
| evidenced by a reoccurrent.e of the fuel strainer misalignment problem
| |
| on the Division II diesel generator, which resulted in the Division
| |
| II diesel generator operability failure on March 17, 1986. This
| |
| inadequate corrective action for the diesel generator operability
| |
| failure on February 14, 1986, was identified by the SRI as an
| |
| apparent violation (458/8614-01).
| |
| b. Performance of Maintenance: As a result of the February 14, 1986,
| |
| Division I diesel generator operability failure, the fuel oil
| |
| strainer valve handle was removed from the Division II diesel and
| |
| installed on the Division I diesel. It was also used as a pattern
| |
| for the maintenance shop to fabricate a new handle for the Division
| |
| II diesel.
| |
| This new handle was apparently fabricated through use of a shop work
| |
| order (SWO), but the maintenance department could not locate the SWO.
| |
| The new handle was installed February 17, 1986, on the Division II
| |
| diesel generator fuel oil strainer, but no maintenance work request
| |
| (MWR) was initiated to provide documentation of work performance or
| |
| to provide for retesting as appropriate. A SWO should not be used to
| |
| work on permanent plant equipment by licensee procedure. This
| |
| failure to initiate a HWR for performance of maintenance on permanent
| |
| plant equipment was identified by the SRI as an apparent violation
| |
| (458/8614-02).

| c.- Inoperable Division II Diesel Generator: 'The Division II diesel '
| |
| ,
| |
| - generator was proved operable on February 15, 1986, by surveillance
| |
| e, ,test, and the new fuel oil strainer valve handle was apparently
| |
| . installed on February 17, 1986. No testing was performed af ter the
| |
| >
| |
| m
| |
| '
| |
| ' handle was~ installed until the March ~17, 1986, surveillance test, ,
| |
| J _ which failed because of the' improper alignment of the fuel oil
| |
| -
| |
| strainer valve. On March 17, 1986, the valve handle was found to be
| |
| improperly posi_tioned on the fuel oil strainer, and the valve was
| |
| misaligned, causing a loss of fuel oil flow to the diesel. There was
| |
| no evidence found of any other maintenance work on the fuel oil
| |
| strainer between February 17, 1986, and March 17, 1986. Also, there
| |
| , was no' evidence ~ found of operational realignment of the fuel oil
| |
| strainer.
| |
| - With the_ plant in Operational Condition I on March 17, 1986, the
| |
| Division II diesel was discovered to be inoperable during
| |
| surveillance testing. .The diesel had apparently been inoperable for
| |
| -
| |
| an undetermined length of time between February 15, 1986, and March
| |
| 17, 1986. This failure to have three separate and independent diesel
| |
| generators "0PERABLE" in "0PERATIONAL CONDITION 1" was identified by
| |
| the SRI as-an apparent Technical Specification violation
| |
| (458/8614-03).
| |
| d. Licensee Investigation and Corrective Actions
| |
| The SRI found that the licensee was continuing his investigation of
| |
| this occurrence, and the following corrective actions were being
| |
| implemented:
| |
| . .The licensee has scribed all three diesel generator fuel oil
| |
| strainer valves so that proper valve positioning is identified
| |
| with or without the handle being installed. Diesel operabi.11ty
| |
| has been verified for three diesels.
| |
| . Maintenance personnel have been instructed on the proper
| |
| alignment of the fuel oil strainer handle and valve.
| |
| . The plant operators are verifying proper position of the fuel oil
| |
| strainers during normal rounds (at least once per shift).
| |
| . The plant manager has added a compliance inspector analyst to
| |
| his staff to assure procedure adherence for conduct of
| |
| maintenance. This person is charged with the responsibility
| |
| ,
| |
| for. compliance to procedures within the maintenance department.
| |
| .
| |
| . The use of shop work orders has been eliminated.
| |
| i
| |
| :
| |
| The SRI will c.ontinue to nonitor licensee actions in this area.
