Enclosure to TXX-99564 August 25, 1989 Pg. 5 of 13 14 INITIAL TEST PROGRAM The testing activities to be performed on safety-related systems at Comanche Peak are divided into three major phases:
prerequisite testing, preoperati:nal testing, and initial startop testing.
Prerequisite testing will be conducted to verify the integrity, proper installa-tion, cleanliness, and functional operability of the system components.
Preoperational testing will be performed to demonstrate the capability of systems, structures, and components to meet safety-related performance require-ments. These tests will be performed on plant systems, structures, and compo-nents that are designed to perform a nuclear safety-related function.
Preopera-tional testing will be completed before fuel loading with certain limited exceptions where tests or parts of tests will be deferred until the core has been loaded.
In such cases, sufficient testing will be performed before fuel loading to provide reasonable assurance that the postloading tests will be successful.
Initial startup tests will be performed beginning with fuel loading and ending with commercial operation.
The intent of these tests is to ensure that fuel loading is effected in a safe manner; that the plant is safely brought to rated capacity; that plant performance is satisfactory in terms of established design criteria; and to demonstrate, where practical, that the plant is capable of withstanding anticipated transients and postulated accidents.
The staff review concentrated on the administration of the test program and the complete-ness of the prerequisite, preoperational, and startop tests.
For example, the staff's Safety Evaluation Report issued at completion of the Construction Permit review (CP SER) was re-examined to determine the principal design criteria for the plant and to identify any specific concerns or unique design features that would warrant special test consideration.
Cha?ters 1 through 12 of the FSAR were reviewed for familiarization with the facility design and nomenclature.
Chapters 13 and 17 were reviewed for familiarization with the applicant's organizational structure, qualifications, administrative controls, and quality assurance program as they apply to or impact the initial test program.
Chapter 15 was reviewed to identify assumptions pertaining to perform-ance characteristics that should be verified by testing and to identify all structures, systems, components, and design features that were assumed to function (either explicitly or implicitly) in the accident analysis.
Licensee Event Reports for operating reactors of similar design were reviewed to identify potentially serious events and chronic or generic problems that might warrant special test consideration.
Standard Technical Specifications for Westinghouse PWRs were reviewed to identify all structures, systems, and components that would be relied upon for establishing conformance with safety limits or limiting conditions for operations.
Finally, the Startup Test Reports for other PWR plants were reviewed to identify problem areas that should be emphasized in the Comanche Peak initial test program.
The object of the staff review of FSAR Chapter 14 is to determine whether the acceptance criteria stated in the Standard Review Plan are met.
The staff review covered several aspects of the initial test program including the following major considerations:

structures, systems, components, and design features that:

(8) The test objective, prerequisites, test methods, and acceptance criteria for each test abstract were reviewed in sufficient detail to establish that the functional adequacy of the structures, systems, components, and design features will be demonstrated.
(9) The test program's'conformance with applicable Regulatory Guides was reviewed.
The review included:
Regulatory Guides 1.20, 1.41, 1.52, 1.68, 1.68.2, 1.79, 1.80, and 1.108.
The applicant made a number of changes to the initial te.st program because of the staff's comments.
Examples of these changes include (1) Administrative controls were added to ensure that all test procedure modifications that alter the acceptance criteria or test intent would be appropriately reviewed.
(2) Additional (five consecutive, cold quick starts) testing of the steam-driven auxiliary feedwater pumps was added to further demonstrate system reliability.
(3) Testing to verify that the reactor cooled pipe penetration cooling system will maintain the pipe tunnel concrete temperature within design limits was added.
(4) The acceptance criteria for certain preoperational and startup tests involving reactor protection system hardware instrumentation delay time, remote plant shutdown validation, diesel generator starting requirements, snubber inspection, battery charger capacity, containment spray flowpath verification, sampling system flowpath and holdup, and power-operated relief valve capacities were modified.
Modified acceptance criteria were required to more accurately reflect the actual test conditions and to provide assurance that system performance will be in conformance with design predictions.
(5) The minimum qualifications for personnel who direct or supervise the conduct of testing were upgraded to conform with acceptable industry standards.
(6) Certain system tests were expanded to ensure that comprehensive system and component testing was scheduled.
Example systems included station service water, component cooling water, vent and drain, spent fuel pool cooling, residual heat removal, chemical and velume control, safety injection, containment ventilation, diesel generator compartment ventila-tion, ac and de power distribution, reactor protection, rod control, steam generator safety and relief valves, main steam and feedwater isolation valves, auxiliary feedwater, pressurizer safety and relief valves, and engineered safety features.
