SUMMARY Scope:
The resident inspectors conducted a routine inspection in the following areas:
operational safety verification; maintenance observation; surveillance observation; refueling activities; action on previous inspection findings; and reportable occurrences. The inspectors conducted t ackshift inspections on :'
October 29 and 30, and November 11, and 22. 199 Results:
A new type of recirculation system jet pump holddown beam failure was identifie Intergrannular stress corrosion cracking initiated failure in a new beam location caused plant management to conservatively extend the outag .
'
'
to replace all twenty four beams (paragraph 6.).
During the restart-from the outage, a resin intrusion from the condensate i storage tank to the' vessel during a reactor core isolation cooling (RCIC)
system test lead to a shutdown based upon the Electric Power Research Institute reactor water chemistry guidelines. The shutdown was delayed for i several hours due to poor communications between the chemistry personnel and j the operations staff (paragraph 3.c.).

'
A Unresolved Item from last month's report (93-15) became a violation when personnel error was determined to be the cause of a loss.of shutdown cooling-(paragraph 8.b.).
One con-cited violation was identified for failure to meet requirements of an LC0 prior to entering a higher operational condition. The Operations staff :
did not place RCIC in an operable condition prior to allowing the reactor to exceed 135 pounds. This event was easily avoidable (paragraph 7.). .

last paragrap ' Plant Status j The Unit was in a refueling outage for the inspection period. The .;
outage was extended for a complete replacement of the recirculation system's jet pump holddown beams. Plant startup was in progress at the end of the perio Duringt@eweekofOctober 25, 1993, Region 11 personnel from the Division of Radiation Safety and Safeguards conducted an inspection in .I the areas of occupational . radiation safety and radiation controls'(NRC j Inspection Report 50-416/93-20). i During the week of November 22, 1993, Region 11 personnel from the Division of- Radiation Safety and' Safeguards conducted a'special inspection-in_the area of radioactive wastes transportation (NRC Inspection Report 50-416/93-22). Operational Safety (71707 and 93702) Daily discussions were held with plant management and various members of the plant operating staff. The inspectors made frequent visits to the control room to review the status of q

equipment, alarms, effective LCOs, temporary alterations, instrument readings, and staffing. Discussions were held as appropriate to understand the significance of conditions observe Plant tours were routinely conducted and included portions of the control building, turbine building, auxiliary building, radwaste building and outside areas. These observations included safety >
related tagout verifications, shift turnovers, sampling programs, housekeeping and general plant conditions. Additionally, the .
'
inspectors observed the status of fire protection equipment, the control of activities in progress, the problem identification systems, and the readiness of the onsite emergency response facilitie No deficiencies were identifie b. The inspectors performed observation of control room activities -
during the startup performed at the end of the period. The reactor mode switch was placed in startup on November 26, 1993, at 7:32 am. Rod movement started about a half hour later. Rod movement was performed with much attention to detail. Personnel'
were rotated pe'iodically to avoid fatigue. Rod control movement 4 was performed in accordance with 17-S-02-400, Revision 5, Control Rod Sequences and Movement Control, and Attachment 1-07-000CO-A2-01. The inspector reviewed the new limits on core operations with ,
respect to core instability with the on shift personnel. The new
'
core power / flow map was finalized November 8,1993. The new map
-
includes a " Region III, Controlled Entry", that requires fraction of Core Boillag Boundary to be calculated. The current computer display has this value. Also,'" Region II, Exit", has.been enlarged. The on shift staff was knowledgeable of the change ;
c. On November 27, 1993, during a reactor startup from the refueling l outage, Grand Gulf's reactor coolant sulfate concentrations !
exceeded the EPRI action level 3 recommendations of 200 pp Concentrations reached 391 ppb for. sulfates and conductivity reached 3.8 mho/cm. Administrative procedures written to enforce the EPRI guidelines required an immediate orderly shutdown of Mr.: ,
plant. About sixteen hours af ter commencing shutdown, sulfate concentrations and conductivity were brought back into l
'
specifications and the unit was scheduled for--restart on November 28, 1993. The licensee suspected that a resin intrusion .
occurred during operational surveillance' testing of the RCIC l system at 150 psi. Resin fines were apparently agitated.from the-
'
bottom cf the CST when the RCIC pump was pumping CST to CS :
After about one hour.of recirculation, RCIC was lined up to the vessel and injected'for about 2 minutes at 800 gpm. Vessel water- jl chemistry samples drawn after the injection showed abnormal ;
readings. RWCU was not available for clean up of the reactor- i coolant during a large portion of the event, due tc an P_WCU isolation and normal system realignments during startu During a review of the sequence of events, the inspectors noted that greater than two hours passed between the availability of the I

chemistry results from the 4:00 a.m. samples and the chemistry department notifying operations of the results. This resulted in an unnecessary delay while reactor coolant chemistry sulfate concentrations were well in excess of EPR:/ Administrative procedural guidelines requiring plant shutoewn. Further investigation by the inspectors revealed weaknesses in the chemistry procedures regarding notification of the control room when chemistry results require operator actions. The licensee initiated a quality deficiency report to further address these concern d. The inspectors observed a simulator training session on the new digital feedwater control system. The session consisted of'a lecture on the updated System Operating Instruction 04-1-01-N21-1, Feedwater System, and hands-on training with the new feedwater controls. Emphasis was placed on the lowered response time (60 seconds to 15 seconds) for full travel of the turbine governor valve, startup and shutdown of the pumps, and startup of a second feed pump. Comments were received from students for procedural enhancements. The session was comprehensive, informative and well presente e. Prior to startup after the outage the inspectors reviewed the status of items committed to be closed prior to the end of RF0 A summary follows: The response to LER 91-005-00, LER 91-005-01 commits to inspect, maintain and test 500kv switchyard breakers on a routine basis, including gas compressor oil analyse The licensee has replaced breaker J5232 and plans to replace breaker J5228 during the next refueling outage. These are tha only Siemens breakers of this type tied to the main generator, and are the only ones scheduled for replacement at this time. -The replacement breakers are Mitsubishi designed breakers. Oil samples were taken from J5228 and other similar Siemens breakers and were sent to an MP&L contractor for analysi . Lic. Cond. 2.C(26) requires that the licensee ultrasonically inspect bores and keyways of LP turbines prior to exceeding 50,000 hrs, of operatio The UT inspection of the No. 3 LP turbine was completed during RF06. Indications were observed on both No. 4 rotor discs but the vendor.has released the rotor for. unrestricted operatio (See Inspection Report 50-416/93-15) In response to IN 93-70 the licensee agreed to load freshly discharged spent fuel in Boraflex surveillance are .

reference leg without the normal pressure equalization. A change of indicated level of six to seven inches was observed. The system was ,
stable for CRD movement and SRV lifting. The residents will review high power test results in a future repor No violations or deviations were identified. The results of the observations in this area indicated that maintenance activities were effectiv . Surveillance Observation (61726)
The inspectors observed the performance of portions of the surveillance listed below. The observations included a review of the procedure for technical adequacy, conformance to Technical Specifications and LCOs; .
verification of test instrument calibration; observation of all or part of the actual surveillance; removal and return to service of the system or component; and review of the data for acceptability based upon the acceptance criteri P-1C71-V-0002, Rev 29 Refueling Interlock Check One-Rod- l Out Interlock '
No violations or deviations were identified. The observed surveillance test was performed in a satisfactory manner and met the requirements of the Technical Specification . Refueling Activities (60710)
During the last inspection period (see IR 50-416/93-15) the jet pump
'
holddown beam from the number ten jet pump had not been located. A '
review was made of the video tapes taken during the prior searches for the beam, and a systematic search found the beam near the number six jet
_
pump. The beam was retrieved, and after an on site visual examination, sent to General Electric's hot cell for examinatio Initial results -
'
indicated the failure mechanism was IGSCC crack initiation and
,
propagation with possibly some fatigue contribution through the last 20%
of the crack. Due to the reduced cross section in the vicinity of the crack, the licensee could not prove that from the time the crack was of detectable size by UT or VT, that failure of the beam would not occur by the next outage. The plant management conservatively chose to perform a complete jet pump beam replacement. As found measurements were taken of ,
the replacement beams and a considerable amount of variance was found in !
some dimensions. Beams with thicker cross sections were use ,
The crack location on the number ten beam was in an area not previously '
found to crack. The inspectors reviewed videos from RF05 and indications of a crack on the beam were not visibl ,

The inspectors observed the decision making process used for determining plant actions to be taken as more information became available on the ,
mode of the beam failure. The inspectors found the decision to be e conservative and based upon technical information aggressively. collected by the licensee. Independent consultants and General Electric provided inpu '
During the period, the inspectors periodically and routinely observed activities on and around the refueling floor and spent fuel pool are Fuel movements observed were conducted in a controlled and deliberate manner and were tracked and documented per P&SE Instruction 17-S-02-300, SNM Movement and Inventory Control. On duty supervisory personnel were aware of the status of ongoing activities when questioned by the inspectors. Jet pump beam replacement activities were well planned and ?
executed, and were completed well ahead of schedul Radiological controls and general housekeeping were goo In addition, the inspectors observed portions of core verification activities, non-destructive examination of the new jet pump beams, and the in-vessel visual inspection of reactor internals. No deficiencies were observe No violations or deviations were identifie . Reportable Occurrences (90712 and 92700)
The event report listed below was reviewed to determine if the information provided met the NRC reporting requirements. The determination included adequacy of. event description, the corrective i action taken or planned, the existence of potential generic problems and the relative safety significance of the event. The inspectors used the NRC enforcement guidance to determine if the event met the criterion for :
licensee identified violation '
On November 26, 1993 at 7:00 p.m., a licensee operator determined that a higher operational condition had been entered while the requirements for an LC0 had not been met and continued noncompliance with the LC0 would result in a shutdown. Technical Specification 3.7.3 requires that RCIC be operable in operational conditions 1,2, and-3 with reactor steam dome j pressure greater than 135 psig. During plant startup from RF06, reactor ;
steam dome pressure increased to 138 psig for approximately 8 minutes with the RCIC system inoperable. Licensee operators took immediate action to reduce dome pressure and declared RCIC operable within 10 minutes of decreasing dome pressure to less than 135 psi This item was licensee identified. and corrective actions were taken !
prior to the end of this report period. The safety significance of this event is low because all ECCS system were operable and would.have performed their design functions. Plant management is aware of the f inspector's concerns with the recent mistakes made by operations while performing activities. Plant management has stressed increased attention to detail in the performance of duties. This violation is not j i

In addition, a Region based specialist was scheduled for a special inspection of this modification during the week of November 29, 1993. This item is close (Closed) Unresolved Item 93-15-02, Loss of Shutdown Cooling. On -
October 4, 1993, at 4:36 p.m., an automatic isolation of the common suction piping for shutdown cooling occurred. The isolation was caused by a failed voltage regulating and current limiting card in one of the battery chargers. On October 7, 1993, :
at 3:13 p.m., operators opened the alternate supply breaker to inverters 1Y96 and 1Y87 and caused a Division I half scram, SBGT A initiation, control room standby fresh air auto start, and multiple isolations of equipment, including the closure of IE12-F009 due to a high reactor pressure signal. Closure of F009 .
caused the RHR B pump to trip, resulting in the loss of Shutdown cooling for fifteen minutes. The operators were hanging clearances and failed to properly verify all indications that the '
inverters were on their normal power supplies prior to opening the alternate supply breakers. Instructions on the tagout requested i verification of the normal power source. A URI was opened on ~
these items because the licensee had not yet verified the root '
cause of the incident An incident review board for these events met on November 3,199
