Ms. Elinor Adensam, Director Project Directorate #3 Division of BWR Licensing Dea r Ms. Adensam:

TURBINE SYSTEM MAINTENANCE PROGRAM (LICENSE CONDITION 3)

HOPE CREEK GENERATING STATION DOCKET NO. 50-354 License Condition 3 of Facility Operating License NPF-50 requires Public Service Electric and Gas Company ( PS E&G) to submit a turbine system maintenance program based on the manufacturer's calculations of missile generation probabilities.

General Electric Company, the manufacturer of the Hope Creek turbine, has completed a probabilistic evaluation of the low l

pressure turbines at Hope Creek.

Based on the attached results and recommendations from General Electric, which are based upon the methodology of GE report, " Probability of Missile Generation in General Electric Nuclear Turbines" dated January 1984, PS E&G will inspect the low pressure turbine rotors f or the unit over a six year interval during scheduled ref ueling outages.

The revised description of the turbine in-service inspection program is attached (FSAR Section 10. 2.3. 6) and will be included in the next update to the FS AR.

In accordance with 10 CFR 170.2 1, attached is a check for S150.00.

l This submittal satisfies the provisions of License Condition (3) and PSE&G requests that the condition be removed at the time that the full-power license is issued for Hope Creek Generating l

Station.

l Sincerely, l

10.2.3.5 Preservice Inspection New The preservice inspection program is as follows:

a.

Wheel and rotor forgings are rough-machined with minimum stock allowance prior to heat treatment i

b.

Each rotor and wheel forging is subjected to a 100%

volumetric (ultrasonic) examination.

Each machine-finished rotor and wheel is subjected to a surface magnetic particle and visual examination.

Results of this examination are evaluated by use of General Electric (GE) acceptance criteria.

These criteria are

[

more restrictive than those specified for Class 1 i

components in the ASME B&PV Code, Sections III and V, and include the requirement that subsurface sonic indications are either removed or evaluated to ensure that they do not grow to a size that compromises the integrity of the unit during the service life of the unit.

l c.

All machine-finished surfaces are subjected to a l

magnetic-particle examination.

No magnetic-particle l

flaw indications are permissible in bores, holes, l

keyways, and other high stressed regions.

l d.

Each fully bucketed turbine rotor assembly is spin-tested at or above the maximum speed anticipated following a load rejection from full load.

b.

The main stop valves, control valves, and combined intermediate valves are inspected and nondestruc',ively tested at a frequency based upon their operation, operational tests, industry experience, and good industry practices.

Critical areas such as the valve stem, seats, valves, bushings, and casings receive an ultrasonic test, liquid penetrant test, or magnetic-particle test, and a thorough visual inspection.

At least one valve of each type will be dismantled for inspection at approximately 3-1/3-year intervals.

If unacceptable flaws or excessive corrosion are found in a valve, all valves of its type are inspected.

Valve bushings are inspected and cleaned, and bore diameters are checked for. proper clearance.

c.

Main stop and combined intermediate valves are exercised at least once a week by closing each valve and observing by the valve position indicator that it moves smoothly to a fully closed position.

High INSERT B - pressure turbine control valves are exercised at least once a month through at least one complete cycle from the running position.

Proper valve motion is verified by observing the valve position indicator.

-o-10.2.4 SAFETY EVALUATION The turbine-generator has no safety-related function.

Failure of the system does not compromise any safety-related system or component or prevent a safe shutdown of the plant.

10.2-13 Amendment 15

HCGS FSAR INSERT A to FSAR Section 10.2.3.6 The following turbine system maintenance program is based upon the manuf ac t ure r' s recommendations and calculations of missils generation probabilities, a.

The i n-s e r vi c e inspection program for the turbine assembly includes disassembly of the turbine in stages over a six year interval during plant shutdowns such that the turbine is inspected within six years.

This includes complete inspection of all normally inaccessible parts, such as couplings, coupling bolts, turbine shafts, low pressure turbine buckets, and low pressure wheels.

This inspection consists of visual, surface, and volumetric examinations, as indicated below:

1.

A thorough volumetric examination of all low pressure wheels, including areas immediately adjacent to keyways and bores, is conducted.

2.

Visual examination of all accessible surfaces of rotors and wheels.

3.

Visual and surface examination of all low pressure buckets.

4.

100% surface examination of couplings and j

coupling bolts.

INSERT B to FSAR Section 10.2.3.6 d.

The extraction check valves will be tested weekly with the turbine on-line and loaded to assure that each valve is capable of being actuated by its l

power cylinder, and to exercise the mechanism so as to keep it free to move.
