The Comission also requested that the Comittee provide its views on the staff's proposal for the use of NUREG-1150 during the period while the report is undergoing peer review.
The Committee prepared a report on the second draft of NUREG-1150 during the Ma 3-6, 1989 ACRS meeting (see report to Chairman Zech referenced above)ybased on a limited review of this draft and plans to continue its review of this draft.
The Comittee discussed a proposed report to the Comission regarding the status of the NRC staff's implementation of the ATWS rule.          The Committee did not complete its deliberations and plans further consideration of this report during its June 8-10, 1989 meeting.
The Committee agreed to attend the second international meeting of nuclear reactor safety committees which has been proposed by the GPR and RSK. The meeting is to be held in Strasbourg, France sometime during the period of April-June 1990. The last meeting between these groups was held in Racine, Wisconsin during October 1986.
Since the last report of ACRS activities, the following subcommittee meetings have been held:
Improved Light Water Reactors, April 11-12, 1989 - The Subcommittee continued its review of the EPRI ALWR Requirements Document.
Containment Systems and Structural Engineering, April 18, 1989 -
The combined Subcommittees discussed current containment design and performance criteria and proposals for containment design and performance criteria for future plants.
Human Factors, April 19, 1989 - The Subcommittee reviewed the Human Factors Research Progrc.m Plan and NRC human factors initiatives,     j Occupational and Environmental Protection Systems, April 20, 1989 -
The Subcommittee discussed proposed interim standards for occupa-tional exposure of the skin to beta radiation from small particles (hot particles).
Instrument and Control Systems April 21, 1989 - The Subcommittee      l discussed the status of the implementation of the ATWS rule.
Limerick Unit 2, April 25,1989 - The Subcommittee reviewed the        l application of Philadelphia Electric Company for a license to operate Limerick Unit 2.                                              ;
