An Act establishing a special legislative commission to study small modular reactors

Maddy summaryThis bill establishes a legislative commission to study small modular reactors (SMRs) as a potential baseload power source. The commission will specifically examine how SMRs can work with renewable energy to improve grid stability, and evaluate non-light water coolants for safety and operational effects. The commission includes key energy committee chairs, legislative leaders, and state agency heads, and must submit a report within one year of the bill's passage. The bill itself creates no new regulations or funding but directs a formal study to inform future energy policy decisions.

The change directly affects deer hunters who can now legally hunt deer on Sundays when the season is open. This is a straightforward policy adjustment to the existing hunting regulations, clarifying that deer hunting during season is permitted on Sundays.

An Act helping employees after a relative’s tragedy

Maddy summaryThis bill establishes a new bereavement leave policy for employees in the Commonwealth, allowing workers to take up to 10 business days of paid leave when a family member dies. The law defines family members broadly to include children, parents, spouses, domestic partners, and others with significant personal bonds, and permits leave to be used for funeral arrangements, attending services, or grieving. Employers must pay employees at their regular rate during this leave, maintain their benefits, and restore their position upon return, though businesses with fewer than 25 employees are exempt. The legislation also requires employers to notify staff of these rights and allows for reasonable documentation of the death, with the law taking effect on January 1, 2027.
