2 (2) I have a Bachelor of Mechanical Engineering degree (1970) and a Master of Business Administration degree (1974).

I completed the General Electric BWR simulator program in July 1976 and obtained certification at the RO and SRO levels. In November 1982, I obtained a Senior Reactor Operator license on Shoreham.

(3) My name is William E. Gunther, Jr. and I have been the operating Engineer for Shoreham since April 1983. My du-ties and responsibilities include the direction of the day-to-day operation and shutdown of all station equipment, final ver-ification of all operating procedures, participation in initial requalification and replacement training programs for licensed and unlicensed operators and the establishment and maintenance of system operability to support fuel load.

(4) I have a Bachelor of Sciones degree in Electrical Engineering (1970) and a Master of Science degree in Electrical Engineering (1971). I earned a Senior Operator Certification from the General Electric Company on the Brunswick Unit 2 BWR in 1975 and I completed the General Physics Company BWR si-mulator program in December 1981 and obtained certification at the RO and SRO levels. In November 1982, I obtained a Senior Reactor Operator license on Shoreham.

i' (5) The purpose of this affidavit is to describe the steps involved in the following phases:

Phase I: Fuel Loading and Procriticality Testing Phase II: Cold Criticality Testing Phase III: Heatup and Low Power Testing to Rated Pressure / Temperature Conditions (approximately.1% rated power)

Phase IV: Low Power Testing (1-5% rated power) t These various phases will be described below, with a brief ex-I planation of the testing and operations to be conducted during ,

each phase.

i Phase It Fuel Loading snd Precriticality Testine

(6) Fuel loading and procriticality testing involve placing fuel in the vessel and conducting various tests of re-actor systems and support systems. Initial core loading in-volves the placement of 560 fuel bundles in specified locations within the reactor vessel. This major step requires signifi-cant testing as fuel loading progresses, and it takes at least 288 hours0.00333 days <br />0.08 hours <br />4.761905e-4 weeks <br />1.09584e-4 months <br />. The following testing is associated with initial core loading:

i-4 (A) Water chemistry surveillance l testing. This testing must be performed l'

' prior to, during and after the fuel loading operation. The purpose of water chemistry ,

surveillance testing is to ensure clarity of

the water so that the fuel loading process can proceed and to minimize the amount of the corrosion products in the primary system.

I i

l (B) Control rod drive stroke time and

' friction tests. These tests are performed during the fuel loading step to ensure that

' the reactor shutdown capability is maintained i at all times and to ensure the control rod drive mechanisms are performing as designed.

(C) Installation, calibration and

utilization of special startup neutron in-strumentation. This instrumentation is re-

! quired for core' loading activities to ensure proper monitoring of core conditions by the

' - Operating, Reactor Engineering and Instrumen-tation and control personnel. Source range j

monitor testing and alignment tests calibrate j

the neutron monitoring instrumentation and verify proper final alignment of this vital

equipment.

(D) Core verification instrument op-l

- erability check. These checks are performed to verify that the equipment utilized to de-termine that the core has been loaded cor-rectly is operable. Final core verification

checks are completed at this time.

i

' The tests listed in (A) through (D) above involve valu-able supplemental training and experience for personnel as-signed to the Reactor Engineering Section, Radiochemistry Sec-

! tion, Operating Section, Maintenance Section and The training described in Instrumentation and Control Section.

steps (B), (C) and (D) can be fully accomplished only during i the fuel load operation. f Following placement of the fuel in the vessel, a

(7) number of tests must be performed to verify the operability of This phase of systems prior to going critical in the reactor.

startup testing takes approximately 150 hours0.00174 days <br />0.0417 hours <br />2.480159e-4 weeks <br />5.7075e-5 months <br /> and includes the ,

following:

(A) Local Power Range Monitor (LPRM) sensitivity data. During this test, the 31 local power range monitor strings are cali-brated and verified to be operable. Instru-i mentation and control technicians will per- .

' form this testing, and obtain training in the use of calibration procedures and special test equipment.

l 5

(B) Zero power radiation survey for background readings. Various locations in i ,

the plant are surveyed by health physics technicians to determine background radiation l

levels with fuel in the vessel.

(C) Recirculation system instrument calibration checks. Operation of the recirculating pumps with fuel in the vessel is conducted to determine core internal pres-sure drops and to verify system performance.

Operation of the system above minimum speeds l

with the vessel internals installed can be accomplished only with fuel in the reactor.

(D) Control rod drive scram time testing. Following fuel load, each control rod drive mechanism is scrammed from its' full withdrawn position following control rod cou-pling surveillance testing to verify that rod -

insertion can be accomplished within the pre-scribed time.

criteria.

Again, the testing and activities described in (A) through (D) above can be accomplished only after fuel has been placed in the vessel. The experience and training gained from 3

these activities will be an invaluable Shoreham-specific aug-mentation to the years of extensive preoperational training that the reactor operators have previously undergone.

Phase II: Cold Criticality Testing (8) This phase involves a specified contro1 rod with-drawal sequence that results in achieving reactor criticality at extremely low power levels ( .0001% to .001% of rated thermal power). In addition, this step involves shutdown of the reac-I ter by inserting all control rods in reverse order. While withdrawing each rod, reactor operators monitor the effect of its withdrawal in terms of neutron flux. By analysis and cal-culation, Reactor Engineering personnel are able to assign a

- " worth" to each control rod, i.e., the effectiveness of each rod in controlling reactivity. Important operator hands-on ex-l perience is gained during this step. Reactor operators must annually perform a minimum of ten reactivity control

F .

manipulations. This experience provides additional training 2 for reactor operators in the use of apprcpriate instrumentation and equipment to determine when criticality is achieved during' the withdrawal of control rods. This important experience on the Shoreham reactor can be gained only after fuel has been placed in the vessel. Similarly, Reactor Engineering personnel obtain valuable training and experience during this closely monitored activity. LILCO plans to repeat the operations dur-ing this phase of low power testing to offer each operating shift crew this valuable BWR experience.

(9) Cold criticality testing requires plant mainte-nance personnel to install vessel internals in accordance with station procedures and with all refuel floor constraints in place. Maintenance personnel gain experience with the op-eration of the refuel bridge and reactor building crane.

(10) Also performed at this time is the installation of the expansion and vibration instrumentation. Cold baseline data are obtained at this point to determine pipe movement as heatup occurs later in the low power test program. The data i

provide a benchmark against which subsequent test results can j be assessed.

The operation of these systems provides valuable training and experience to operating plant personnel, including

- licensed operators. LILCO plans to repeat certain of the ac-tivities in this phase of low power testing to provide addi-tional, valuable BWR operating experience. It 12' estimated that I

there will be 5000 total manhours of training accomplished and achieved during fuel loading, precriticality tacting, and cold criticality testing described above.

Phase III: Heatup and Low Power Testing to Rated Pressure / Temperature Conditions (Approximately 1% Rated Power)

! (12) During this phase of low power testing, reactor heatup and pressurization commences and the power level is taken in progressive steps to 1% of rated power. Along the i

way, the heatup and pressurization of the reactor vessel and associated piping systems enables the plant staff to perform important tests relating to thermal expansion of piping and in-tegrated system operation under actual operating conditions.

The principal steps associated with this phase of low power testing are described below.

(17)- With the reactor coolant system pressure between 550 psig and 800 psig, the following testing is performed: .

(A) Conduct a drywell temperature in-spection and gather data for system thermal expansion tests; (B) Obtain Reactor Building Closed Loop t

Cooling Water System (RBCLCW) performance data; (C) Scram selected control rods to ob-tain scram time data.

(18) With the reactor coolant system pressure at 800 the following occurs:

psig and heatup to'920 psig, (A) Scram selected control rods for scram time data; (B) obtain system thermal expansion data for nuclear steam supply systems and balance of plant systems.

Phase IV: Low Power Testing (1-5%)

(19) During this phase of low power testing, the power level is taken in progressive steps from 1% to 5% of rated thermal power. With the reactor coolant system at rated tem-perature and pressure, the operator will withdraw rods and open one Main Turbine bypass valve to establish a steam flow such that core thermal power is less than 5% rated thermal power.

Once this condition is established, the following tests are performed:

During this heatup, the key activities include:

(A) Demonstration of the source range and intermediate range monitor response to control rod withdrawal; (B) Gathering of system thermal expan-sion data; (C) Calibration of the average power range monitors.

(22) When the plant is at rated temperature and pres-sure, the plant staff verifies that core thermal power is less than 5% rated thermal power by performing a heat balance.

a After the verification of core thermal power is complete, RCIC cold quickstart and endurance run are performed.

(23) Subsequent to the completion of the second test period at 920 psig, the plant will be. cooled down to ambient conditions. During this cooldown, the plant will obtain nuclear steam supply system thermal expansion data for the sec-ond time. When ambient conditions are reached, the icw power tests are concluded. Repeated startups and heatups to rated conditions will be performed at Shoreham, however, so that each operating crew can be given the opportunity to experience plant response to the tests and activities presented above.
