is able to accurately identify zones

requiring improvement for fire prevention

or for other safety concerns. Previous

regulatory evaluations determined

only the degree of compliance;

i.e., they gave no indication of whether

a safe shutdown could actually be

achieved. The proposed method helps

to ensure that safe shutdown can be

achieved, based on the safety requirements

stipulated in existing regulations.

Safe shutdown capability can

be used as a criterion by which to

identify the elements that cannot

feasibly conform to regulations, such

as areas where automatic fire detection

and extinguishing systems cannot

be installed. TRIZ is an innovative

approach to problem-solving. It provides

a range of possibilities by which

to solve problems and the results are

easily compiled to facilitate training

procedures. Few existing studies on

nuclear power plants apply directly to

real-world cases. Knowledge management

methods enable the construction

of a knowledge base, thereby providing

a means by which to integrate

implicit and explicit knowledge. Its

systematic integration of analysis and

comparison data provide valuable a

reference to practitioners in the field.

Parameter settings based on

current regulatory conditions and

the use of knowledge management

models enables quicker and more

precise identification of the improvements

required for compliance with

existing regulations. A fire prevention

database provides a valuable reference

for the assessment of fire safety.

Subsequent tasks include developing

fire models and automatic analysis

instruments based on fire dynamics,

fire load, and fire risk probability,

which all require such databases. The

basic fire prevention database in this

study meets the basic requirements

for fire analysis and can be used for

future studies of post-fire phenomena

in nuclear power plants. The procedure

outlined in this study provides a

model for safety assessment of current

nuclear power plants as well as a

complete research framework for

other fire-related research in nuclear

power plants and even other types of

safety measures. The nuclear power

plant studied in this paper features

three-loop pressurized water reactors.

Therefore the details of the research

procedure related to the water

reactors are not necessarily applicable

to other types of reactor. Data

collection, analysis, and comparison

would have to be performed anew

to confirm its applicability.
