Licensee Actien en Previous Inspe_ction Finding _s.
(Clesed)
Unreselved item (254/78-24-03; 265/78-25-03) - Chanping the lubricant used in the limit switch gear assembly to Mebil Grease No. 28.
There was ne documentary evidence that the grease is environmentally qualified. The RIII inspector reviewed a letter from Limitorque to Commonwealth Edison dated February 7, 1976. based cn the test data defined in che Lititerque " Nuclear Qualification Data Sheet" dated Nevember 15, 1977, the inspecter has ne further questiens on this matter.
(Clesed)
Nencompliance (IE Rpts 254/77-31; 265/77-31) - Failure to perfer adequate tests to determine that replacement compenente meet the design specifications of the original plant compenents.
The inspecter found that the licensee had initiated action ite:
4-78-2 to increase surveillance testing cf the temperature switches. Results of this test will determine the quality of the new switches.
(Closed)
Noncompliance (IE Rpts 254/78-11; 265/78-13) - High Radiatien gate open with ne positive centrol ever entry. The inspector verified that the fellowing corrective actions had been taken:
Signs have been posted en all high radiation doers; Orders have been placed in the Night Order Book requiring that operators check high radiation doors and gates once per shift; Station Construction Department supervisors have instructed their-2-

.
.
't personnel about the importance of r cess control; and a fact sheet has been develeped en radiation regulations for usc during erfentation of contractors.
(Closed) Noncempliance (IE hpts 254/78-14; 265/78-15) - Startup precedures were net adhered to.
The inspecter confirmed that orange colored plastic rings have been provided to use when placing a pump inte pull-to-lock. The licensee also reviewec precedures QOS 6500-1, QTS 110-1 and QTS 110-3 to assure thet ECCS pumps are returned to an operabic status fellowing test completien.
(Clesed) Noncompliance (1E Rpts 254/78-14; 265/78-15) -
Imp 1cmentation of procedures prier te being authorized by the Station Superintendent. The inspecter confirmed that t ht.
methed of issuin; temporary precedures and temperary chanres te precedures has been changed. Precedures QAP 1100-7 anc QM 1100-T1 and the Temperary Procedure Request Fern have beet.
revised to require that temporary procedures and changes to precedures which change the intent of the procedure Le reviewc b; the On-Site Feview Group and approved by the Statico Superinte:, dent prior te implementation.
(Closed) Open Item (IE Kpts 254/77-12; 265/77-12) - Cable penetratien seul material documentatien not availatle at site.
The inspecter confirt:.ed that the documentation was new en sit <.
(Closed) Open Item (LER 254/77-30) - Modification te prevent bulb-secket sherts. The inspecter neted that the licensee har develeped a test circuit and is testing it in the recirculatic:
MG set lubc oil pump system.
(Closed) Open Item (LER 254/77-34) - Replacenent of reacter building te terus pressure switcher. The licensee has completec installatien of new pressure switches for Units 1 and 2.
(Closed) Open Item (LER 254/77-20, 77-33) - The inspecter noted that the turbine 1st stage pressure switch drift probler is being reselved. The new switch setting appears to be adequate.
No items of noncempliance or deviations were identified.

were made using proper procedures, codes, and functiencl testin1 Design change er modificatien packages for each of the follewin, areas were reviewed:
Control rod drive thernal sleeve removal (MOD 2-75-1) ESS MG set under frequency /over frequency receva.
(MOD 2-78-3) torus level sight glass (MOD l-74-42) RCIC turbinc exhaust check valve disc (MOD l-74-56) isolation of ECCS valves (MOD 2-72-6) dryvell/terus delta P instrumentation (MOD 2-77-13).
The inspection established that all design changes er medificaticas are initially assigned an identification nunber and fret thc:
peint on the design change er tedificatien is controlled by adherence to a review and apnroval precedure and check sheet.
This control requires the re 4;wers te take detercinations suct as:
Is the work safety related, is a 50.59 review required; is a special cede work required; what special procedures arc required; what final verificatien testinE is requirec.
In additien to the individucl files, a master status boek is mcintained such that the status of each item can be readily determined.
Ne itets of nencompliance er deviations were identified.
Review of Plant Operationf
_
The inspector reviewed the plant operations including examinatiens of centrol rect leg books, reutine patrol sheets, shift engineer leg books, equiptent cutage legs, special eperating orders, j u=per and tagcut legs, for the period of August 21, 197c threugt Nevenber 7, 1978, and records pertaining te reacter coolant quality for August, September, and Octobet. The inspector noted that leg boek reviews were being conducted by management, and that canning of the centrel reet was in conformance with the requirements of the Technical Specifications. The inspecter alsc cade visuel observations of the routine surveillance and functiensi tests in progress.
5.
Plant Tour Tours of the plant were made during each inspection day te determine that monitoring instrumentation is recording as required, radiatien controls are properly established, the adequacy of housekeeping, the existence of fluid leaks and pipe vibrations are minimal, equipment cautisn or lockout tag information corresponds to that identified in the control rect, and selected valve positions are correct. Discussions were conoucted with the control room operators relating to the reasons for selected lighted annunciators.

Office Review of Licensee Event _Regern The inspector reviewed licensee's event reports to ascertain whether corrective actions described in the reporte mppear appropriate end whether information reported to the NRC satisfies reporting requirceents. The following event reperts were reviewed and are considered closed:
a.
Ro 50-254/78-25/03L, dated August 29,1978, "liPCI lurbint Area High Temperature Switch Instrument Drift."
b.
RO 50-254/78-27/03L, dated Octeber 5, 1976, "Diesc1 Fuel Transfer Line Out of Serv.cc."
c.
RO 50-265/78-28/03L, dated August 16, 197E, "Pressurc Suppression Chamber to Reacter Building Vacuur Breaker Instrurent Drift."
Ne itens of noncompliance er deviatiens were identifir_.

Site Review cf Licer.see Event Rep e_r_t2 c
Licensee Event Reperts were reviewed te verify that details were accurately reported; that the cause was identified; that the ;"ent was reviewed and evaluated in accordance with Technical Specificatiens; and that corrective action was taken as described in the repert. The following LER's were reviewc;.
RO 265/76-19/03L, dated May 4, 1976, "Rlik Piping Pressure a.
Less tnan Required." During steady state operatien it was discovered that the discharge piping pressure in "i/
LPCi icop was less than 40 psig. Cause of the occurrence was failure of a flew centrol valve to allew fill water te enter the LPCI discharge piping. The inspecter verified that repairs were cade and the systet was returned te normal.
b.
R0 265/78-26/01T, dated June 28, 197S, " Failure of HPCI Governer Valve." b'hile performing the menthly HPCI pure operability surveillance, the required HPCI turbine speed ceuld not be obtained. Cause of the event was a disconnected linkage which caused the turbine control valve te go closed. The inspecter verified that the linkage was repaired.

R0 265/78-30/03L, dated September 26, 1978, " Pain Steam Line Radiation Moniter Failed Downscale." On August 31, 1978, the MSL Rad Monitor failed downscale. The devnscale failure was enhanced by higher than normal ambient tenperatures due to work being done on the service building ventilation system. The inspecter determined that the corrective actions taken were adequate.
Ne items of noncompliance or deviations were identified.
