- Technical Specification Change Request No.101 The licensee requests that the attached changed pages replace pages 4-7, 4-8, 4-39, 4-41, 4-42, 4-44, 4-46, 4-48, 4-55 and 4-55b of the existing technical specifications. Each change is to become null and void and the specification shall revert to its prior state upon completion of that specific surveillance modified by'that change. All surveillances modified herein shall be performed prior to full power operation.

Reasons for Changa Request These changes modify the surveillance requirements to allow the refueling interval to be extended to restart of TMI-1. These surveillances would exceed the time limit in August 1981 should this change not be approved.

Further reasoning for requesting these extensions are discussed with each specific change.

Safety Evaluation Justifying Changes It has been determined that these changes do not pose a threat to the health and safety of the public, in that, all postponed surveillances will be per-formed prior to full power operations. Further safety evaluations are included with each specific change.

License Amendment Fee (10CFR 170.22)-

This change does not involve any Unreviewed Safety Questions, therefore, the licensee has enclosed the required remittance of $1200.00.

Technical Specification- Change Request No. 101.1-Safety Evaluation Justifying Change Specification 4.12.2 " Reactor Building Purge Air Treatment System" requires operability of that system be ensured at least once per refueling.

This surveillance is required to be current whenever the reactor building purge air treatment system is required to be operable. However, this system is only required to be operable when containment integrity is required.

To ensure that this condition does not occur when this surveillance is not current, the applicable operating procedures are being revised to include verification that this surveillance is current as a prerequisite for establishing containment integrity.

In addition, this surveillance is scheduled to be performed af ter completion of the system modifications. These modifications are tentatively scheduled for completion in April 1981. Since plant heatup for Restart requires containment integrity to be set, this surveillance must be performed prior to Restart.

It is therefore conditionally concluded that the postponement of the performance of this surveillance will not endanger the health or safet:f of the public, is not a safety hazard and does not constitute an Unreviewed Jafety Question.

The condition on which this conclusion is based prohibits the establishment of plant operating conditions which require containment integrity.

! initially and after any maintenance or testing that could affect the air distribution within the system. The air distribution across the HEPA filter bank shall be uniform within 20%. The test shall be performed at 25,000 cfm ( 10%) flow rate.

  • Surveillance to be performed prior to Cycle 5 criticality. l l

Bases Pressure drop across the combined HEPA filters and charcoal adsorbers of less than 6 inches of water at the system design flow rate will indicate tha the filters and adsorbers are not clogged by excessive amounts of foreign matter.

Pressure drop should be determined at least once every refueling interval to show system performance capability.

Technical Specification Change Request No. 101.2 Reasons for Change Request Specification 4.12.l'" Emergency Control Room Air Treatment System" requires operability of that system be verified at least once per refueling.

This surveillance is required to be current whenever the control building emergency recirculation system is required to be operable. However, this system is only required to be operable when containment integrity is required and when irradiated fuel handling operations are in progress.

Safety Evaluation Justifying Change To ensure that these conditions do not occur when this surveillance is not current, the applicable operating and refueling procedures are being revised to include verification that this surveillance is current as a prerequisite

~

for establishing containment integrity and for the moving of irradiated fuel.

In addition, this surveillance is scheduled to be performed upon completion of the HVAC system balancing, tentatively scheduled for June 1981. Since plant heatup for Restart requires containment integrity to be set, this surveillance must be performed prior to Restart.

It is therefore conditionally concluded that the postponement of the per-formance of this surveillance will not endanger the health and safety of the public, is not a safety hazard and does not constitute an Unreviewed Safety Question. The conditions on which this conclusion is based prohibit the movement of irradiated fuel and the establishment of plant operating conditions requiring containment' integrity.

Technical Specification Change Request No. 101.3 Reasons for Change Request Technical Specification Table 4.1-2 Item 4 requires the main steam safety valves be operable prior to the reactor coolant system reaching 250 degrees Farenheit.

However, this surveillance cannot be performed due to present plant conditions because the plant must be at power and main steam pressure at approximately 885 psig. Therefore, we are requesting an exemption from specification 3.4.6

- to allow heatup to at least 532 degrees F. for. testing of the steam. valves during the startup and test period.

Safety Evaluation Justifying Change All the main steam valves are technically operable because exceeding the 24 months between tests has not degraded the valves. Since the shutdown, these valves have not been challenged and have been kept in conditions which should not promote corrosion. In addition,'since the last previous surveillance test, the valves have not been subject to maintenance that would change the setpoints.

4.7 REACTOR CONTROL ROD SYSTEM TESTS 1

- 4.7.1 CONTROL R0D DRIVE SYSTEM FUNCTIONAL TESTS Applicability Applies to the surveillance of the control rod system.

Objective To assure operability of the control rod system.

Specification 4'.7.1.1 The control rod trip insertion time shall be measured for each control rod at either full flow or no flow conditions following each refueling outage prior to return to power.* The maximum l control rod trip insertion time for an operable control rod i

drive mechanism, except for the axial power shapping rods (APSRs),

from the fully withdrawn position to 3/4 insertion (104 inches travel) shall not exceed 1.66 seconds at hot reactor coolant full flow conditions or 1.40 seconds for the hot no flow conditions.

For the APSRs it shall be demonstrated that loss of power will not cause rod movement. If the trip insertion time above is not met, the rod shall be declared inoperable. .

4.7.1.2 If a control rod is misaligned with its group average by more than an indicated nine inches, the rod shall be declared inoperable and the limits of Specification 3.5.2.2 shall apply. The rod with the greatest misalignment shall be evaluated first. The position of a rod declared inoperable due to misalignment shall not be included in computing the average position of the group for determining the operability of rods with lesser misalignments.

4.7.1.3 If a control rod cannot be exercised, or if it cannot be located with absolute or relative position indications or in or out limit lights, the rod shall be declared to be inoperable.

  • The control rod trip insertion times shall be verified prior to Cycle 5 criticality.

Bases The control rod trip insertion time is the total elapsed time from power inter-ruption at the control rod drive breakers until the control rod has actuated the 25% withdrawn reference switch during insertion from the fully withdrawn position. The specified trip time is based upon the safety analysis in FSAR, Section 14.

Each control rod drive mechanism shall be exercised by a movement of approxi-mately two inches of travel every two weeks. This requirement shall apply to either a partial or fully withdrawn control rod at reactor operating conditions.

Exercising the drive mechanisms in this manner provides assurance of reliability of the mechanisms.

Technical Specification Change Request No. 101.5 Reasons for Change Request Specifications 4.5.2.1 and 4.5.2.2 "High Pressure Injection" and " Low Pressure Injection" require system tests be performed on at least a refueling interval basis. The HPI test must be done when the Reactor Coolant System Temperature is

>3200F. The LPI test could be performed at this time except that modifications are being performed on the ESAS.

Safety Evaluation Justifying Change The tests will be completed prior to criticality, and in the present mode neither system is required operable. Therefore, it has been determined that the postponement of these surveillances to prior to criticality will not endanger

, the health or safety of the public, is not a safety hazard, and does not constitute an Unreviewed Safety Question.

Technical Specification Change Request No. 101.6 Reasons for Change Request Specification 4.5.2.3 " Core Flooding" requires a system test be performed on a refueling interval basis to ensure the check and isolation valves operate properly. This test is normally done while at a Reactor Coolant System pressure of approximately 530 psig.

Safety Analysis Justifying Change i

No credible accident can be proposed that would require the operation of the Core 11ooding System while in the present plant condition. The test will be performed prior to Cycle 5 criticality. It has been determined that the postponement of this surveillance will not adversely affect the health and safety of the public, is not a safety hazard, and does not constitute an Unreviewed Safety Question.

I 4.5.2 EMERGENCY CORE COOLING SYSTEM Applicability Applies to periodic testing requirement for emergency core cooling systems.

Obj ective To verify that the emergency core cooling systems are operable.

Specification 4.5.2.1 High Pressure Injection

a. During each refueling interval and following maintenance or modification that affects system flow characteristics, system pumps and system high point vents shall be vented, and a system test shall be conducted to demonstrate that the system is operable.* l After a satisfactory test of the emergency loading sequence (4.5.1),

b. The test will be considered satisfactory if the pumps and fans have been successfully started'and the valves have completed their travel

! as evidenced by the control board component operating lights, and either the station computer or pressure / flow indication.

' Bases The emergency core coo' .ry; systems are the principal reactor safety features in the event of a los of coolant accident. The removal of heat from the core provided by these syteems is designed to limit core damage.

i The low pressure injectiu tmips are tested singularly for operability by i

opening the borated water rage tank outlet valves and the bypass valves in j the borated water storage tm i fill line. This allows water to be pumped from the borated water storage tank through each of the injection lines and back to the tank.

The minimum acceptable HPI/LPI flow assures proper flow and flow split between injection legs.

l <

l With the reactor shutdown, the valves in each core flooding lines are checked for operability by reducing the reactor coolant system pressure until the indicated level in the core flood tanks verify that the check and isolation valves have opened.

Technical Specification Change Request No. 101.7 Reasons for Change Request Specification 4.5.3.1.b " Reactor Building Cooling and Isolation System" requires on a refueling internal bases the cooling water valves be opened using an ES test signal. The Engineered Safeguards System is currently disabled for modification preventing performance of the test.

Safety Analysis Justifying Change The reactor building emergency coolers are required when the reactor is critical to. remove heat from the reactor building during a postulated high energy pipe break. The unit is currently restricted to a cold shutdown 3

condition, therefore, the potential for a high energy pipe break does not exist. The test will be completed prior to startup, therefore, there is no adverse effects upon the health and safety of the public, it is not a safety hazard, and does not constitute an Unreviewed Safety Question.

b. Reactor Building Cooling and Isolation System
1. During each refueling period, a system test shall be conducted to demonstrate proper operation of the system.* After a l satisfactory test of the emergency loading sequence, a test signal will actuate the R. B. emergency cooling system valves to demonstrate operability of the coolers.
2. The test will be considered satisfactory if the valves have completed their expected travel as evidenced by the control board component operating lights, and either the station computer or local verification.
  • The system test shall be conducted prior to Cycle 5 criticality.

4.5.3.2 Component Tests

a. At intervals not to exceed three months, the components required'for reactor building cooling and isolation will be tested,
b. The test will be considered satisfactory if the valves have completed their expected travel as evidenced by the control board component operating lights, and either the station computer or local verification.

Bases

  • The reactor building cooling and isolation systems and reactor building spray system are designed to remove the heat in the containment atmosphere to prevent the building pressure from exceeding the design pressure.

The delivery capability of one reactor building spray pump at a time can be tested by opening the valve in the line from the borated water storage tank, opening the corresponding valve in the test line, and starting the corresponding pump.

With the pumps shut down and the borated water storage tank outlet closed, the reactor building spray

  • injection valves can each be opened and closed by the operator action. With the reactor building spray inlet valves closed, low pressure air can be blown through the test connections of the reactor building spray nozzles to demonstrate that the flow paths are open.

The equipment, piping, valves and instrumentation of the reactor building cooling system are arranged so that they can be visually inspected. The cooling units and associated piping are located outside the secondary concrete shield. Personnel can enter the reactor. building during power operations to inspect and maintain this equipment.

The reactor building fans are normally operating periodically, constituting the test that these fans are operable.

normal A-C station service power supply together with a simulated engineered safeguards actuation signal. This is required each refueling interval.

The engineered safeguards actuation system is currently disabled for modifi-cations thus preventing performance of this test.

Safety Analysis Justifying Review The test will be conducted prior to startup. High and low pressure injection systems are not required to be operable in a cold shutdown condition. 'The emergency power system is being tested monthly, thereby assur!ng that the onsite source of power is operable. Since the high and low pressure injection systems are not required to be operable during cold shutdown, there is no adverse effect upon the health and safety of the public, it is not a safety hazard, and it does not constitute an Unreviewed Safety Question.
