DAVIS-BESSE NUCLEAR POWER STATION UNIT NUMBER 1 TECHNICAL REQUIREMENTS MANUAL INTRODUCTION a

Based on the NRC's Final Policy Statement on Technical Specification Improvements for nuclear power plants, and 10 CFR 50.36 as amended in Final Rule published in the Federal Register dated July 13, I

1995, certain requirements may be relocated from the Operating License Technical Specifications to other licensee controlled documents. In an effort to centralize the requirements relocated from the Technical Specifications and to ensure the necessary administrative controls are applied to these 4

requirements, the Davis-Besse Technical Requirements Manual (TRM) has been developed.

The TRM provides one location for relocated items in a consistent format. The TRM retains the current Technical Specification numbering for relocated items with one exception. This exception is for the i

BASES section. Instead of being in a separate section, the BASES immediately follows the LIMITING CONDITION FOR OPERATION (LCO) and SURVEILLANCE REQUIREMENTS. 'Ihe TRM contains its own DEFINITIONS which may not be the same as the Operating License Technical Specification i

DEFINITIONS.

REGULATORY STATUS /REOUIREMENTS 2

Although the TRM itselfis not legally binding like the Operating License Technical Specifications, the requirements in the TRM are part of the licensing basis. Furthermore, the TRM is incorporated by i

reference in the Updated Safety Analysis Report (USAR) and is considered to be part of the USAR.

Violations of the TRM requirements should be documented by the PCAQ process.

These controls are in place because the purpose of relocating the requirements for Technical Specifications is not to reduce the level of control on the items but to provide flexibility for change under the 10CFR50.59, Safety Review / Evaluation, process.

Deviations from the TRM will be screened for reportability in accordance with the PCAQ pro.:ess.

l CHANGES TO THE TRM Design modifications, procedure changes, license amendments, etc. have the potential to affect the TRM. If this occurs, the initiating department must follow the administrative controls in NG-NS-00806, 2

/*

1.1 Definitions The defined terms of this section appear in capitalized type and are applicable throughout the Technical l

Requirements Manual.

Ican Definition e

ACTIONS ACTIONS shall be those additional requirements specified as corollary statements to each principal requirement I

and shall be part of the requirements.

CHANNEL CALIBRATION A CHANNEL CALIBRATION shall be the adjustment,

[

as necessary, of the channel output such that it responds with necessary range and accuracy to known values of the

]

parameter which the channel monitors. The CHANNEL CALIBRATION shall encompass the entire channel including the sensor and alarm and/or trip functions, and l

shall include the CHANNEL FUNCTIONAL TEST.

l CHANNEL CALIBRATION may be performed by any l

series of sequential, overlapping or total channel steps such that the entire channel is calibrated.

O CIIANNEL CHECK A CHANNEL CHECK shall be the qualitative assessment of channel behavior during operation by observation. This l

determination shall include, where possible, comparison of j

the channel indication and/or status with other indications j

and/or status derived from independent instrument channels measuring the same parameter.

CHANNEL FUNCTIONAL TEST A CHANNEL FUNCTIONAL TEST shall be:

a.

Analog channels - the injection of a simulated signal into the channel as close to the primary sensor as practicable to verify OPERABILITY including alarm and/or trip functions.

1 l

b. Bistable channels - the injection of a simulated 4

signal into the channel sensor to verify OPERABILITY including alarm and/or trip functions.

1-1 REV.1 02/21/96 i

CORE ALTERATION CORE ALTERATION shall be the movement of any l

fuel, sources, or reactivity control components, within I

i the reactor vessel with the vessel head removed and I7 j

fuel in the vessel. Suspension of CORE I

ALTERATIONS shall not preclude completion of I

movement of a component to a safe position.

OPERABLE - OPERABILITY A system, subsystem, train, component or device shall be l

OPERABLE or have OPERABILITY when it is capable

definition shall be the assumption that all necessary attendant instrumentation, controls, normal and emergency electrical power sources, cooling or seal water, lubrication or other auxiliary equipment, that are required for the system, subsystem, train, component or device to perform its function (s), are also capable of performing their related support function (s).

OPERATIONAL MODE An OPERATIONAL MODE shall correspond to any one inclusive combination of core reactivity condition, power level and average reactor coolant temperature as specified below.

JASES i

4.0.2 The provisions of this requirement provide allowable tolerances for performing surveillance i

activities beyond those specified in the nominal surveillance interval. These tolerances are necessary to provide operational flexibility because of scheduling and performance considerations. The phrase "at least" associated with a surveillance frequency does not negate this allowable tolerance value and permits the performance of more frequent surveillance activities.

'Ihe allowab'. tolerance for performing surveillance activities is sufficiently restrictive to ensure that the reliability associated with the surveillance activity is not significantly degraded beyond that obtained from the nominal specified interval. It is not intended that the allowable tolerance be used as a convenience to repeatedly schedule the performance of surveillances at the allowable tolerance limit.

The allowable tolerance for prforming surveillance activities also provides flexibility to accommodate the length of a fuel cycle for surveillances that are specified to be performed 18 at least once each REFUELING INTERVAL. It is the intent that REFUELING INTERVAL surveillances be performed in an OPERATIONAL MODE consistent with safe plant operation.
