1.0 Summary of Operating Experience Low Power (.001%) Operating License NPF-19 was issued to the Shoreham Nuclear Power Station by the U. S. Nuclear Regula-tory Commission on December 7, 1984. Following receipt of this license, the operational sources were loaded into the reactor vessel on December 17. Fuel loading commenced on December 21, and was completed on January 19, 1985. Initial reactor criticality occurred at 6:25 P.M. on February 15, which was followed by two days of core physics testing. The core reactivity was found to be within .06% of its design value, well within the acceptance criteria.
All testing that could be performed under the license limi-tation of low power testing at atmospheric pressure was completed on February 17. For the next four and a half months Shoreham was maintained in cold shutdown pending receipt of an operating license that would authorize Phase III and ,IV activities as described in several licensing submittals before the Low Power Atomic Safety and Licensing Board. During this outage a vessel leak test was performed and the Control Rod Drive mechanism cooling water orifices were cleaned and replaced to correct a low flow problem caused by spalling of scram inlet valve seats which were made of Teflon.
Following the issuance of the Partial Initial Decision on emergency diesel generators LBP-85-18, operating license NPF-36 was issued on July 3, 1985, enabling low power testing at power levels not to exceed 5% of rated power.
Plant heatup commenced on July 7 and continued for three months. On July 14 the first reactor scram occurred (one of only four to occur during the year) . Rated reactor pressure was reached on August 7, followed by a gradual heatup.
Testing was performed at intervals during this and subse-quent heatups to ensure that all systems were operating correctly. The events comprising initial criticality and low power testing are described in the Startup Test Report (Reference SNRC-1216).
Repeated problems were experienced with the reactor level instrumentation, the most serious of which resulted in an Unusual Event being declared on September 8 and the fourth reactor scram on September 12. The root cause was traced to inadequate slope for portions of the reference legs of both loops. Interim corrective action was taken and a permanent modification is now complete.
On September 27 an alert was declared, in accordance with Emergency Planning Procedure EPIP l-0, when the eye of Hurricane Gloria approached to within 10 miles of the plant.
The reactor had been shut down in anticipation of this occurrence. No damage occurred to the plant.

On October 6 the main turbine generator was rolled to rated I speed, but was not synchronized to the grid. On October 8 1 essentially all testing possible under the existing low power testing license had been completed. The reactor was shut down on that date, and remained shut down through the end of the year. Major activities during this outage in-cluded replacement of the neutron sources and implementation of the remaining Environmental Qualification Modifications (Reference SNRC-1235) .
At the years end the reactor was in Cold Shutdown, with the t vessel head removed and the reactor cavity fully flooded while plant modifications were being performed.
t 2.0 Summary of Operating Experience Relating to Safety-Related .
I Non-Corrective Maintenance N During 1985, Safety Related Maintenance performed during non-outage periods consisted primarily of Preventive Maintenance Program implementation and minor corrective Maintenance tasks in support of the Power Ascension Test Program. Preventive Maintenance has been classified into two major categories, Mechanical / Electrical, and Instrument and Controls (I&C).
1 In the category of Mechanical / Electrical, 924 preventive I tasks were completed and in the I&C category, 413 tasks were completed.
Additionally, LILCO continues to perform surveillances and preventive maintenance activities as suggested by the engine manufacturer on the Transamerica DeLaval, Incorporated emergency diesel generators. The specific preventive maintenance activity which began in the November - December 1985 time period fulfills the eighteen month surveillance requirement contained in Section 4.8.1.1.2, paragraph e, item 1, and is expected to be complete by mid-April 1986.

3.0 Summary of Events Conducted During Outage Between February 17 and July 7, 1985, Shoreham was shut down pending issuance of the low power testing license NPF-36.
During this outage a vessel leak test was performed and the control rod drive mechanism cooling water orifices were cleaned and replaced. There were no reportable occurrences pertaining to this outage.
On October 8, 1985 Shoreham's heatup. testing under the existing low power testing license NPF-36 was completed except for the synchronization of the main turbine generator to the grid. The reactor was placed in Cold Shutdown to replace the neutron sources and to perform several plant modifications. LILCO installed various pieces of equipment necessary to satisfy the - Commission regulation concerning environmental qualification of electrical equipment, 10 CFR 50.49; increased the number. of fire detectors and relocated others to enhance the fire protection program; made necessary changes to the post-accident sampling facility; and performed other minor modifications.
3.1 Reportable Occurrences Licensee Event Reports (LER)85-006, 85-017,85-020, 85-038,85-042 and 85-043 prompted an engineering evaluation for modifications to the "A" and "B" water level instrumentation reference legs. Materials were ordered in December for these modifications and work is now complete. LER 85-055 reports on the completion of replacement of electrical equipment that was not environmentally qualified per 10CFR50.49 and license condition 2.C.8 of NPF-36.

3.3 ECC Systems Outage From December 7, 1984 to December 31, 1985 there were 65 limiting conditions for operations (LCO's) for the ECC Systems. 32 of the 65 LCO's were actual require-ments per Technical Specifications. The remaining 29 were for tracking. At Shoreham, an LCO is categorized as a " tracking LCO" if the technical specification LCO occurred while the reactor was in an operational mode other than that for which the LCO is applicable. It is for this reason that the HPCI inoperability due to the turbine exhaust check valve problem is not included in the table describing the thirty-two (32) LCOs.
Tracking LCOs are none-the-less important because they provide assurance that operability will be restored prior to entering the applicable ope, rational mode. Of the 32 actual LCO's the breakdown is as follows.
16 are for Ell, Residual Heat Removal (RHR) 6 are for E21, Core Spray (CS) 9 are for E41, High Pressure Coolant Injection (HPCI) 1 is for all the ECC systems l
These 32 actual LCO's are detailed in Table 3.3-1 indicating for each component by system the outage dates, duration, and the reason for the outage. 24 of the 32 actual LCO's placed the system inoperable due to surveillance testing. 8 were due to equipment failure.
The corrective action for these are described below.
LCO 85-325 Problem description: Panel lH21-PNL-103B power supply inverter IB21-INV-625D output failed low-no power light on.
Corrective Action: Replaced with new inverter.

LCO 85-350 Problem description: Thermal blew as valve lE41*320MOV-041 went shut. Valve was found fully shut when thermal was reset.
Corrective action: Found valve operator torqueing too
- hard into seat. Torque currents were 70-118 amps.
Lowered torque switch to 1.0 from 1.5 and torque currents dropped to 15.8 - 24.9 amps.
LCO 85-442 Problem description: With flow on RHR "A" Loop, valve
. Ell *MOV-42A did not open when closed down.
Corrective action: Replaced two broken electrical terminal connection lugs for this valve.
LCO 85-453 Problem description: Water level indicators for the "B" reference leg read high and diverged from the water indicators for the "A" reference leg due to excess condensate accumulation in the steam line leading to the condensing chamber.
Corrective action: Added additional insulation and installed a hanger on the line to assure that line slope remains constant.
LCO 85-476 Problem description: Locking screw broke on flow switch making the switch repeatedly inaccurate.
Corrective action: Replaced flow switch with new one.
LCO 85-482 and 85-483 Problem description: Leak discovered at pipe weld test connection near MOV-40A.
Corrective action: Repaiaed leak in weld pipe to coupling connection.
LCO 85-487 Problem description: HPCI suction relief valve lE41*320RY-145 leaks. Found disc and seat pitted.
Corrective action: Repaired valve: machined and lapped seat and disc.
