Rules For Highlighting Of OLRFD Drawings Oconee license renewal flow diagrams (OLRFD) are flagged and highlighted to establish the license renewal system evaluation boundaries of the mechanical systems identified in Sections 2.4 and 2.5 of OLRP-1001. The system intended functions required during and after a design basis event, identified as "DBE", are highlighted on flow diagrams to associate specific mechanical flow paths with the performance of the system intended functions. The methodology and criteria used to determine the mechanical flow paths supporting DBE mitigation and for flagging and highlighting the drawings includes the following:
Identify all mechanical flow paths which are relied upon to remain functional during and following design basis events on mechanical flow diagrams by identifying on the drawings all of the flow paths necessary for the system intended functions to be accomplished, as well as those that may functionally prevent those systems from performing their intended function.
This identification may include SSCs that have been traditionally identified as being non safety-related at Oconee.
Identify the non-safety-related flow paths whose failure may adversely affect essential systems or equipment by highlighting all the Duke Class D piping on mechanical flow diagrams. Duke Pipe Class D piping systems require both piping pressure boundary and structural integrity under seismic conditions.
Identify all interfacing flow paths which share a common pressure boundary with the flow paths identified above. Examples of this include branch lines and instrument lines off of highlighted mechanical flow paths.
Identify mechanical safety-related piping which is defined with Duke Class A, B, C, or F piping classifications. These Duke pipe classes indicate that the piping is QA-1 and corresponds to Safety Class I, II, or III of ANSI N18.2-1973. To ensure completeness in mechanical component screening, flow paths within the boundaries of piping systems containing these piping classifications are included in the scope of License Renewal.
Differentiate between Class 1 and Non-Class 1 piping and components. Class I piping and components are defined as those located within ISI Class A piping and are highlighted in yellow. Non class 1 portions are highlighted in blue.
Systems which are relied upon to perform or support performance of a function that demonstrates compliance with the NRC regulations described in paragraph 54.4(a)(3) are within the scope of license renewal. All mechanical flow paths which are necessary to allow the system to perform or support a required system intended function for the regulated events are flagged and highlighted.
The result of this methodology is a set of flagged and highlighted flow diagrams which identifies the license renewal evaluation boundaries corresponding to the scoping criteria in 10CFR54.4(a)(1) through 54.4(a)(3).
Additional guidelines used in flagging and highlighting the OLRFD drawings are:
On vents, drains and test connections, line is only highlighted to outlet of valve.
To keep "Clutter" of drawings to a minimum, no LR flags are placed on Vents, drains and test connections. LR boundary is always at the discharge of the valve.
All instrumentation lines normally open to the process system through, but not including the instrument, are included in License Renewal. These lines are not highlighted except for containment penetrations.
