MODIFICATION TO THE RELAP5 CODE MAINTENANCE 3ROGRAM CONTRACT NUMBER NRC 04-97-039 Replace Item C.I.3, TASK AREA,2 of the contract Dy the. following:

TASK AREA 2:

Perform code maintenance and improvements as detailed in the following subtasks with strict adherence to ANSI standards so as to assure code portability. code accuracy by quality assurance testing. documentation of code improvementJ,. and code integrity and traceability procedures.

The work is to be performed in a Quality Assurance (OA) environment.

Subtasks:

1.

Perform engineering analyses of user-reparted errors and document those analyses. +.he safety significance of the problem and their priority.

Correct the errors based on the priority assigned by the NRC Project Of ficer.

If any error requires a significant resource (more than one o

staff-month) to correct. the contractor shail provide to the NRC Project Officer a written evaluation and proceed with the error correction only after written approval from the NRC Project Officer. Should there be a cost impact. the contractor shall not proceed without written Contracting Of ficer approval.

Conduct all code configuration controls according to applicable IEEE GA standards, or equal.

Define OA for error corrections and code improvements and submit a report describing these procedures (see Section F).

2.

Incorporate the following user convenience features into the existing Symbolic Nuclear Ana.jsis Package (SNAP). and update the design document and user's manual:

(a)

The data dialogs for hydrodynamic components snglvol, tmdpvol.

sngljun, tmdpjun pipe. annulus. branch. separatr. valve. accum, and prizer that reflect the state of the code upon importing an input deck. and allow a user to change the values for future exporting of an input deck.

(b)

The ability to import RELAP5 decks and display the hydrodynamic volumes on the screen and provide a degree of untangling.

The ability to handle all RELAPS input cards either through parsing or copying, will be tested through a matrix of integral and separate effects input decks.

r

(c)

A save function which a: U c. '

( f)

The ability to launch a RELAPS calculatt w 3.

Perform the fol1owing code improvements.

Testu.g and documentat1on of the modification and test results shall be in conf m mance with the accepted QA requirements:

(a)

Support the NRC in diagnosing reported non condensible gas problems. develop a robust numerical model of non-condens10le gas.

Implement the model in the RELAP5 code. test and modify as needed.

and document the modification and results of testing.

(b)

Implement the three-dimensional (30) kinetics model and the general interfacing sofhare, that are developed elsewhere. In the RELAP5 code. test and verify thc modification, and document the modification as well as the results of verification.

(c)

Review the wall friction model for the annular flow in the RELAP5 code for the reflood case and develop a modification as necessary implement. assess, and document the improvement " wellas the results of the assessment.

(d)

RELAP5 15 known to have mass conservaticn anomalies that are believed to be a cause for code failures lhe contractor shall review user results containing significant mass errors and develop a set of simplified test problems to capture the mass error in more complex systems simulations, Identify the root cause of the mass error and develop a correction.

l' a ement the correction to RELAPS and assess the modified code. Document the code modification and the results of the assessment.

(e)

Take advantage of advances in computer capabilities to modernize RELAP5 for easier maintenance and future modification.

Specifir work to be performed under this task are: (1) Remove the blt packing and convert the logical bits into logical words. (TT) Re-engineering large subroutines. and (111) modernize the input I

processing subroutines. Source code modification and results

The process shall be structured mc wtomated in the extent practical and shall contain assessment cabn suf f1cient to test and verify the code capabilities and the impact of the code ch3nges.

Prior to release of new versions of tne codes. the contractor snail 6

perform a comprehensive developmental assessment. using a v.10e range o:

The developmental assessment comparisons shall ne automated to ensure that each new version of the code has gone tnrough all previous development assessments.

The assessment data case stW ~ r=

expanded with applicable test cases as appropriate.

6.

Existing code manuals shall be maintained and updated when improvements error corrections are made and concurrent with the release of a new er version of the code.

The manuals shall be maintained in an electronic format as well as submitted to the NRC Project Officer for publication as NUREG/CR reports.

ESTIMATED LEVEL OF EFFORT The estimated level of effort for the performance of task area 2 is 6,700 bcurs.

PERIOD OF PERFORMANCE The period of performance for the performance of task area 2 is November 18, 1997 through April 23, 1998.
